Title: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!
Post by: BlueBMW on July 23, 2011, 03:18:56 PM
Version 3 of the region mod chip is now available! This new chip does not require that you run wires to each hucard slot pin. It fits directly on the pins for easy slim installation. Installation time is around 15 minutes (compared to previous models which could easily take an hour or more)
Pricing is $18 for the mod chip and $3 for postage Switchless confirmed working. Available soon!
ARCHIVE -- Old information for the 1st and 2nd version region mod chips.
Version 2 of the region mod boards are now available and can be purchased from Turbokon directly via his website: http://www.tg16pcemods.com/ Region Mod Chip $16 + $2.50 shipping to US Switchless Control Board $4 extra
Any questions, feel free to PM either myself or Turbokon.
I wrote up an installation manual that can be downloaded here (~15mb) http://www.mediafire.com/?ad5obr3lls4usm3
As some of you know, thesteve and I have been working on making up some nice new region mod chips for these consoles. Well the boards and parts have all arrived, and I have started to assemble chips! I've tested these in a US Turbo Duo and a US Turbo Express. They work perfect!
These chips will work with a SPDT slide switch just like the other IC based region mods. These require that you cut 8 of the connections going to the hucard slot and run wires to them. If you don't feel comfortable soldering very small connections, you should probably have this done by someone experienced.
Optionally, a second control chip board can be used to run the mod 'switchless'. By 'switchless' we mean there will be no switch mounted externally on the device. This was designed for the portable systems so one doesn't have to cut up their Express or GT (or maybe even LT :shock:) to perform a region switch. In this setup, the original region is default and the second region is selected by holding the select button while powering the unit on. NOTE: This doesnt not work on console systems! It still requires a button press on boot which cannot be done on consoles like it can on portables!
The pricing on these chips will be as follows:
Region Mod Chip $18 shipped Switchless Control Board $4 extra
If you need a switch or wires with your chip, let me know!
I wrote up an installation manual that can be downloaded here (~15mb) http://www.mediafire.com/?ad5obr3lls4usm3 Please send me a PM if you are interested!
Dimensions on the chips are 0.70" x 0.850" by 0.15" for the main chip, and 0.70" x 0.65" x 0.15" for the switchless control chip.

I just successfully installed my first 'Obey' mod chip in my Turbo Grafx. The guide was easy to follow and made the installation trouble free. A bit nerve racking cutting hucard slot pins but overall a fun and rewarding experience.
The best part of the whole process is doing the end test and seeing a PC Engine game load up for the first time :dance:....woohoo, success!
Thanks guys for creating such a great product. Looking forward to the RGB amps as well.
Now that I had a warm up, on to attempting the switchless region mod on my Turbo Express.

just a 2 notes on the express. 1: solder bridge JP1 to enable mode latch. 2: the switch board install can be tested before installing the control board by connecting the control wire to +5 for original region, and Ground for swap.
corrected info

Just finished modding my Turbo Express with the switch-less region mod and it's great!
thesteve...Thanks for posting your install pics and for the tips. They helped me a great deal. I first followed the guide for the switch-less mod install and when I finished, I had major issues with PCE games freezing and glitching. I then used some slightly thicker gauge wire and re-routed the ground and power wires like the pictures and now it works perfectly.
Thanks again for creating/offering these awesome mod chips. :D

Post by: thesteve on September 02, 2011, 05:27:58 PM
that's interesting, that it solved the issues for you. the wire routing shouldn't have changed anything, however if you were having wire failures (broken/ came loose ect), then using different wire would solve it. just as a note I am using #26 wire, and it fits the holes perfect.

Post by: csgx1 on September 02, 2011, 06:39:33 PM
It's quite possible that my issue could have been caused by a damaged/broken wire. All connections were double checked and were secure.
I was thinking the glitching and freezing when booting a non-native (PCE) hucard was caused by the switch board not getting consistent power through longer and thin wire....possibly? In any case, the issue was fix after changing and re-routing the wires.
Any updates on the RGB amps?
Title: Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!
Post by: BlueBMW on September 03, 2011, 01:52:53 AM
I know the very small 30 gauge wire can easily get damaged even just by handling / bending it a few times. Going with larger wire (26 gauge) may be a better bet. A weak wire could certainly cause glitching.
If anyone else has had installation issues, please let me know!
As far as RGB amps, they're still a little ways off. I'll be working on the design for them this weekend some more. :D

edojapan's TG16 is the first US system I've ever heard of needing the pin 29 grounded on in order for the region switch to work. I'll be adding a note to the install guide. Maybe some of the very late (or very early) TG16s were a little different as far as region lockout goes.
Congrats on the great install edojapan!

Title: Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!
Post by: allyourblood on September 14, 2011, 03:06:05 PM
A few shots of my installed chip and switch. I gave up shrinking the tubing on the wires after I kept having them come free in the process; I just slid it on there, but they're all wedged together so well that there's no fear of exposure or shorts. Darn 30 gauge wire can be touchy sometimes. The blue 26g wires connected to the switch in the first shot were just there for a quick and dirty test. I was going to replace them all with the smaller wire but the last few seemed to fit fine without bulking things up too much inside.
I'll do better with the next one. Many thanks to BlueBMW for the supplies and install tips! Wonderful service and very easy to install.
It all went together nicely, but I haven't got a US game to test properly yet. The Regular Japanese games work fine. I'll keep an eye on its function though, i'm worried i've used too thin a wire for power and GND after reading csgx1's findings. I'll post here if I do have problems to let everyone know.

By the way, I'd like to point out that when the instructions say use 26 gauge wire, don't use 24 just because that's all Radio Shack had. I had to get Beemer to fix mine... I messed up a trace probably because the 24g is hard to work with in that tiny area.
I'm going to keep an eye out for a cheap Core Grafx or white PCE so I can try it again sometime.

I have used some crazy thin wire in the past without any trouble at all. Then again those were all on 8pdt region mods and not ones that require any 5V power to be tapped. I can't remember what gauge it was exactly but I sometimes use old IDE cables for PCs that only have one strand of wire in each instead of multiple ones. It is very thin and I actually prefer this cause then it is easier to solder the wire straight through the holes on the motherboard instead of trying to solder the wire to a bent metal pin.

Post by: phipscube on October 29, 2011, 11:56:51 PM
Well, I can confidently say my GT works flawlessly with the thin power wires. The only problem I have is when my Eneloop batts start to run down if I don't turn off the system before the screen goes completely white then it seems to crash and the gfx corrupt. But thats a known issue with the mod installed. So once I notice the screen starting to brighten, I switch off...... (Off topic, but MAN those eneloops last nearly TWICE as long as regular Alkalines!!!!)

congrats phips
keith the reason the #30 wire was an issue, is it breaks easily, and doesnt solder as well as #26 multistrand

I had a hard time with my Duo R cause I'm a soldering n00b but I sent it off to TheSteve along with my GT and he fixed em up right for me. They work great and man, the GT is just so cool with the switchless region mod, just hold down select when you turn it on for the other region and it's like magic! I have a pretty random mix up of US and JP hu cards so it's totally rad to be able to just use them on my system without hassling with the region switch boards. Thanks Steve and BMW for all the hard work put into making these!

The Express/gt had an active matrix lcd that was far superior to any other console at the time. It was hard to read text in some games though and the screens a tad small. Some people dont like the idea of modding an original system, but once you see the new screen you wont go back. I dont care if the system is original, i just wanna play it as best as possible. Steves work improves the experience a ton. I like to play alien crush alot on the new screen.

Not quite, the project stalled out when I got busy working on x68000s lol. I have a nearly complete PCB design, but there were a few changes I'd still like to make to it:

Blue, I received a security bit from turbokon yesterday so I cracked open my TG-16 last night and started this mod. EXCELLENT instructions! I've only completed half the mod (started late in the evening), but it's been fun! Well, fun and stressful! Cutting those HUcard pins sent "holy shit" thoughts through my brain with each pin I cut (except pin 18 8) ). I'll take pics once I've completed the mod. Hopefully tonight.
For the TG-16 do you have any recommendations for placement of the region PCB? I would like to put the RF shields back on and I want the region chip somewhere safe.

Post by: BlueBMW on June 04, 2013, 01:35:45 PM
I usually just double-sided tape it to either the top of the hucard slot or nearby on the system board. There's so much room inside the TG16 that there shouldnt be much trouble making it fit! :D Just watch your wires and the edges of the RF shielding. At times I've cut away some of the RF shielding to make more room for wires coming and going. I always tape the edges of cut RF shielding with some felt tape to make sure it doesnt cut anyone should the unit be taken apart again.

Blue have you ever just left the thin RF shield off? I can see putting the fat RF shield back on without any issues, but the thin one won't fit without cutting it (like you said) with region chip mounted on the HUcard slot or PCB. Dat shit is tight!
I had to solder the wires for the Motherboard on the opposite side and wrap them back around. There was no way the soldering gun was going to fit under the HUcard pins without me undoing all the wire work I had done on the HU pins or melting the shit out of my shrink wrap.

The RF shielding is not critical. It was to meet FCC rf emissions rules. Note that the pc engine models dont have such shielding and operate fine without them. The one exception is the Super CDROM2 models which have grounds linked by rf shields and wont work right without them installed.
Bottom line, if you need to cut some of the shielding to make room for your mod, by all means do it! Just watch the sharp edges when you do.

I finished soldering up everything 5 minutes ago. All the connections look good. H goes to the HUcard side and P to the PCB for all the pins. I didn't have a SPDT switch so I ripped up an old clock radio and reused a switch from it. Then I carefully put the motherboard into the housing and slid the TG-16 into the expansion for my TG+CD docking base. I tossed in a spare Keith Courage and flipped the power switch. The TV screen went white. So I flipped the switch for my old clock radio. No change.
I'm thinking the switch is no good. It's a 2 position switch, but it has 6 solder connections. It was only ever meant to be temporary. I just wanted to test my install and it was the only thing I could find.

You can temporarily just connect A to B or B to C to test without a switch.

Yeah, I tried A to B and B to C, but I get the same results. Just a white TV screen.
I measured pin 38 just to make sure I was getting voltage. This is the pin I used to power the region mod chip. I'm getting 5V so power is getting to the region mod chip. I also triple checked the wiring just to make sure I didn't have pin 19 going to 20, or an H going to a P. Solder connections look good so I'm a little stumped at what to try next.
I also took a volt meter and measured A, B, and C. I get 5V on pin A, but 0 on the others. I'm going to take some isopropyl alcohol and clean everything up next, but after that I'm not sure what to do.
Any advice?
FYI, I'm confident with my solder work. I went to college for an Electrical Technician course where 50% of our grade was lab work involving soldering. I've done mods like this before, and have to work with PCB's quite frequently. I'm trying to tell you I'm competent. :)

Hmmm... It sounds like youve verified each line is correct and youve got good 5v and ground.... I can see no reason why it wouldnt work... I havent had any chips come back bad yet, though I suppose it is possible. Kf you are certain all the lines are connected correctly then I can only suspect it might be a faulty chip. I can send you another one asap if youd like. Though Id hate to make you have to solder another one.

I'll keep you posted. I plan on resoldering the entire thing this weekend so I'll find out if it's me or the chip. I would have done it tonight, but I ran out of desolder braid.
Have you ever tested the region mod chip using a TG+CD docking base? Also, I read something about grounding pin 29 back in the first few initial posts of this thread. Maybe that was for a Duo?

Pin 29 is for japanese systems to disable a hardware region lockout. Shouldnt matter if youre using the system with a cdrom base or not.

with the cart removed the mod can be tested with a meter it works just like a switch (with a few ohms in the chip) so you should be able to measure the continuity from the motherboard to the slot

Makes sense. I don't like the location so I'm going to move it to another area of the MB. This means resoldering pretty much everything, but once I'm done I'll definitely test the continuity at the HUcard slot.
Can I assume that B to C (measuring 0 volts) is for NTSC and that A to B (measuring 5V) is for Japan?

Still no luck BlueBMW, and thesteve. :(
Last night I removed the region mod chip (RMC) and every piece of wire I had used. I threw the 26 gauge wire I had used into the garbage and replaced it with some 30 gauge stuff from my workplace. The sheathing has an extremely high threshold to heat and I find it easy to work with so I figured I would try it. I replaced every single piece of wire and started soldering everything back together. When I was done I inserted a spare KC HUcard again and inserted the raw MB into the expansion bus of the TG+CD docking base (I wasn't reassembling everything again to test it out). I connected B to C with a few simple twists, powered up the docking base, and then powered up the TG-16. Same result - white TV screen. To be thorough, I removed the KC HUcard and inserted Legend of Hero Tonma (PCE) instead. Then I connected A to B and powered everything up again - same result (white TV screen).
Disheartened, I grabbed my multimeter and checked for connectivity from the "H" connections on the RMC to the HUcard slot. I used the underside of the RMC for checking connectivity. All 8 wires passed. I did not check the connectivity for the "P" connections as these 8 wires are the shorter of the runs and also much easier to solder. It was also midnight. 8) I did inspect them visually and they look perfect.
Tonight I will check the "P" side for proper connectivity and I will also install a proper SPDT.
In the past, or when you guys install the RMC, do you reassemble the entire console before testing? I don't want to put the whole thing back together without making sure it passes first, but I'm wondering if the RF shielding needs to be there for proper ground. I have my doubts. I am really just grasping at straws here.

I always test them apart... but on the tg16 I dont run it long since part of the rf shield acts as a heatsink for the voltage regulator.
If you still have no luck, Ill mail you another chip or two and some cash for your wasted time.

Don't send me any cash! If I ignore the fact that I can't get this thing working and that there's been no payoff, it's still been a fun and interesting project.
Do you really think it's the RMC? I mean there's only a single component on it.
Here are a few pictures. Maybe I'm missing something plain as day. This first pic is me unpackaging the brand new RMC from the Ziploc. I was concerned about some of the solder on the chip. In the picture you can see there is already solder filling holes 19P and 21H on the PCB.
Here's a shot of my second attempt at this installation. It's the underside of the TG-16 MB. I'll post a shot of the top side (HUcard side) tonight. I just happened to have this underside pic on my phone. On my first attempt I mounted the RMC on top of the HUcard slot as you show in the instruction manual, but I didn't like the placement (I didn't want to cut anything) so I relocated it when I had to redo all the soldering.
Do you see anything I may have missed? It's hard to tell in the pic, but who knows.

Did you run a wire for ground on the chip?
Also, you can snap off the unused switchless board part.
Title: Re: Turbo Grafx 16 / PC Engine / Express / GT Region Mod Chips for sale!
Post by: FiftyQuid on June 07, 2013, 07:59:39 AM
Yes I did. I ran it in after I took this picture. I have it soldered to the left of the "CN102" connector. Right above the number 37, and 38 on the MB. It's soldered to one of the spots the RF shield is usually soldered.
Yeah, I know I could snap the useless bit off, but it helps me whenever I'm soldering (gives me something to hold) so I just left it on.
[EDIT] I installed a proper SPDT switch today. No luck. I'll try removing everything and reconnecting the original HUcard pins this weekend. If that doesn't work then I have killed :shock: a TurboGrafx-16.

*Double post*
So tonight I removed the wiring and the RMC from my TG-16. I had a hard time believing the region mod chip was at fault so I decided to wire everything back the way it was. It wasn't easy, but I think it came out pretty nicely;
So I wired everything back to factory default and insert it into the TG-CD docking base. I flipped both power switches. Nothing. Just the same white TV screen. I check the RCA cables (again) to ensure they are plugged in correctly and are inserted into Video 1. They are. I pull out the Keith Courage HUcard and insert another one. Same result.
I'm baffled. I don't know what has happened, but it's obviously something I did while trying to mod the console. It definitely was not the region mod chip at fault. Old PCB's like this aren't exactly complicated, but I don't know what the issue is. Visually the MB looks identical to what it looked when I first cracked open the housing. The fuse is good, capacitors are good. The only visual difference is some very minor melting (visable in the pic) on the HUcard slot where I came too close with the soldering iron.
As a last ditch effort, I went ahead and soldered the RF shielding back into place. My thought process being that maybe it provided a GND that I wasn't aware of. Unfortunately, it didn't help. The result was still a white TV screen.
For anyone reading this, I would like to state whole heartedly that I do not blame the region mod chip for this failure. This is obviously a user error (the user being me). I obviously screwed something up at some point along the way.
I will remove the RF shielding later this weekend and inspection the MB closer. If anyone has any troubleshooting methods for getting my TG-16 working again I'm all ears.
I may have just killed a TG-16.
*prays to turbo gods for forgiveness*
[EDIT] BlueBMW, the reason why I mentioned pin 29 earlier was because of this post;
Quote from: BlueBMW
edojapan's TG16 is the first US system I've ever heard of needing the pin 29 grounded on in order for the region switch to work. I'll be adding a note to the install guide. Maybe some of the very late (or very early) TG16s were a little different as far as region lockout goes.
Congrats on the great install edojapan!
It's from earlier on in this thread.

So the obey chip version 2 is just about out. Fear not, we are working on a newer smaller form factor version that will cut down on installation time. The new obey chip will install and solder on the hucard slot 9 pins. Best of all, it will work on all turbografx and pce systems including the turbo express and pce gt. Unlike previous versions of the obey chip, the main and switchless chip will be on one board.

The new region boards are on its way. It should arrive this Thursday.
The new region boards are on a flex board. The way it works is that it folds 3 times like an "S". The 9 hucard slot pins are severed leaving a 1/4 from the bottom and 1/4 from hucard slot. There are soldering holes that lines up and place on the pins coming from the main pcb and soldering pads that lines up to the hucard slot pins. There are 3 soldering holes for the wires for the switch.
Assembling these will be painful because of the small sizes of the passive components (sizes 0402) but I will know for sure when I get them. Also the fab of the boards were more expensive then the last version so the new price will be $18 to $20 before shipping for the main board and still $6 additional for the switchless board option for the gt/te.

New obey region board vs old. I will do a video of an install after our little vacation sometime next week.
A little oops. Aside that how does it work compared to the old mod? About the same? I was just wonder if it'd perform better or not.
It should perform better especially with the everdrive since the data lines are a lot shorter without the use of wires.
We will get another batch run. We are double checking everything again and will go with bigger footprints for the components.

:D
Just installed the oBey mod chip into the PC Engine Duo! Even though I've done a bit of repair work on and off, I never got around to doing a mod. This bothered me so I bought a few chips from Turbokon at MGC last year and this weekend a bit of magic happened.
I cut the pins, and installed the shrink-tubing and I was thinking to myself "what the f*ck, not only is there no turning back but this shit is pink and it looks ridiculous." On top of it my Hu-Card slot was flipping me the bird.
After a snag or two I realized that there was a large blob of solder connecting pins 20 and 21, so I cleaned it up and bent the wires with a small needlenose pliers so that the chip would be level with the heatsynch. I then encased the chip and all of the wires in a bit of bubble wrap (an idea that I got from doujindance, although I have no Idea why also he has like 3 f*cking RGB boards, an elephant and the encyclopedia britannica inside the systems he resells). I then bridged pins 29 and 30 on HU6280.
The chip went in, I mounted it on the RF shield above he Hu-Card slot, and cut a hole in the back of the case for a low-profile I/O switch. I filled in the edges with clear epoxy and double-checked the connections so that they could be quickly desoldered in the event of a repair.
but here is my working install as per BMW/Turbokon's guide and help in chat from chop5 and thesteve:
It should perform better especially with the everdrive since the data lines are a lot shorter without the use of wires.
We will get another batch run. We are double checking everything again and will go with bigger footprints for the components.
I have a TED v2.4. I have not tried nor do I have a previous version. But in all the systems I have installed the Obey V2 chip in all worked fine with the TED v2.4.
I've done more than these 3 but these are the best ones I have done with a clean look.
I am sure I can do better but as they say, practice makes perfect. These 3 systems are also using Turbokons RGB amps. The black PC Engine Duo I found using a connector to be extremely helpfull in case I needed to go back into the system I also use a thin velcro to mount the chip so I can move them or remove them a lot easier than using double sided tape.

Here is the new revised version 3 obey region chip. Tested and working on a turbografx-16. We're still testing on an express using the switchless function.
Main chip is $18 plus $3 shipping, add $6 for switchless option.

So if i understand correctly, the switchless chip does not work on consoles ATM? I have a US TG16, so i would need to install a switch as well, correct?

That is correct. It require you ran a wire directly to the select button. You can't do that on the home consoles.

So the obey chip version 2 is just about out. Fear not, we are working on a newer smaller form factor version that will cut down on installation time. The new obey chip will install and solder on the hucard slot 9 pins. Best of all, it will work on all turbografx and pce systems including the turbo express and pce gt. Unlike previous versions of the obey chip, the main and switchless chip will be on one board.
Did my design influence the v3? Also did you test the TED at all? The only reason I haven't released my boards was because thesteve never figured out how to get the TED to work in the coregrafx consoles, or never told me if he did...

actually we have tested with everdrive and have yet to have an issue as far as influence this is what i was shooting for in the first place, but TurboKon wasnt comfortable with soldering such small parts tho i could say they were both influenced by me

What version of the TED are you testing with? Maybe that's the difference...

well i just tried a 2.4 in my modded express that refused to run in a DoujinDance modded DUO and it works perfect also TurboKon tested the ED2.4 on a white PCE with the flex board (ver3)

Excellent! So 2.4 is the hardware version or OS or firmware? That could be the reason mine isn't working, it's a v1.1 board! That the TED I sent you for testing with my pcb on the CG and white pce. So you didn't have to add the pull-downs or the bigger cap for it to work on the CG and white pce consoles, like you suggested on mine?

right, this is a 2.4 board everdrive (dont know what bios) didnt have to do anything to it, no pull-up/down or added caps

So I finally had the time to sit down and install the V3 Obey - man, works like a charm! :) Now I gotta pick up some PCE games!!

Hey guys, I finally updated the guide for obey version 3 region chip. It was almost two years overdue. Sorry it took so long.
