Kind of a genius idea, actually.

Interesting but ultimately pointless.  I'd much rather have a fully functional flashcart or at least a better game (I like M.C. but I'd play Soldier Blade or Bonk more).

We need to invite that guy to come here and talk about it.  See if he made the mod?

Dan suggest he added a rom cart - sonce the built in couldn't do that - and added a dip switch. simple

I predict it'll sell for over 150, which is plenty high for a tg-16 with no accessories or physical games. Anyone think it'll go for less than that?

Well, it's got a TurboBooster and a TurboPad, so those count as accessories, eh?
Title: Re: Built in Magical Chase
Post by: stockspyder on September 12, 2013, 11:11:42 AM
Didn't notice the booster at first, I still predict that price 150, 200 at the most, but I hope no one is that crazy. I had meant no accessories that weren't included with the system (power,pad, ac)

Make one with built-in Bonk, Soldier Blade, maybe Bomberman...and I'd be set.

Does he use a flashcrad or a real MC?

If it's a flashcard it's nothing else than selling roms over ebay.

I would like to know how he did this. Would be a cool mod.
Title: Re: Built in Magical Chase
Post by: Tatsujin on September 12, 2013, 03:08:00 PM
I guess, he used a simple bus switcher (few 16-bit or two 32-bit or a mixture) between the fix installed Hucard and the hucard-slot.

I would assume he used a pin-compatible eprom, mounted it on the board, and just switched the output enable line.
But that's just me.

Could you mount a flashcard and have all games play out of the box just like one of those TV plug and play games?  Would be a cool mod to have the games "built in."

Another good idea would be to add every US game individually and have 90+ unlabeled dip switches.

i seen that this morning just browsed past it thinks the wording was wrong, well interested to see how it was done.
Title: Re: Built in Magical Chase
Post by: c0ldb33r on September 13, 2013, 12:28:55 PM
This is neat but the dip switches are ugly as sin. Too bad he didn't use a nice switch.
Title: Re: Built in Magical Chase
Post by: Keith Courage on September 15, 2013, 07:13:06 PM
I think it is a stupid and pointless mod. However, if he gets a lot of money for it maybe we will start seeing these all over the place.

This is a fun little mod but could be executed a bit more elegantly I think... anyway it seems to be an attempt at making some quick and easy money in this case. yawn

I'm much more interested in this empty place on the TG motherboard for a built-in ROM. anyone has more information? Pictures?
Is this space present on PC Engines or only the Turbo Grafx? (I saw a white PCE locally for a fair price that I would happily buy if I could experiment with installing custom built-in ROM) In chat I heard it was only 128K possible...?

anyway, please share with me any more info via PM or a post! thanks! :) (sorry if the information is available and I missed it in my searching) I'm really curious

Ahh secret #22!

Quote



Secret 22: The TurboGrafx-16 had two unused IC pads for a built-in game that never happened. One was a kind of switching controller for the other, which would house the actual game. It couldn't be a very advanced game though, the largest game possible would have been a mere 128k (1Mbit). Perhaps The Nu-Kote Kiosk (See secret 23) used this capacity? /quote]

I got my TG16 open for caps, so I am gonna see how easy it will be to wire in a 32 pin JEDEC socket while I'm at it. Hopefully most of the places will line up with the 23c1000 mask rom and I will on need a few jumper wires to the cart slot header. I'm thinking a small SPST 5mm button with a pullup resistor can be used for chip enable.

I missed this thread the first time around so I'm glad to read it now.

As someone already posted, the eBay auction is just a lame attempt to exploit and profit.

HOWEVER, the IC pads and potential for a built-in game/application is AWESOME.

DOES ANYONE KNOW HOW FOLKS WOULD INSTRUCT CONSOLE TO BOOT-UP the built in game? Are there any references in the BIOS that hint at something like, "Press and hold SELECT whilst turning on console to access built-in game" sorta thing?

How did the built-in SMS snail maze game work? Any clues gleaned from internal guts of SMS?
Title: Re: Built in Magical Chase
Post by: bust3dstr8 on March 02, 2014, 03:59:40 AM
The SMS had a few different bios revisions, some included a few small games.
I'm pretty sure the included game would play when there was no game cart detected.

this sounds illegal to me. not to mention the DIP switches that he used on the side look pretty crappy.
Title: Re: Built in Magical Chase
Post by: bust3dstr8 on March 02, 2014, 05:36:04 AM
After looking this over and seeing what is needed to do...I agree, this mod is pure crap  =;
