Sega Genesis power base converter question

[SNKNostalgia]

You just follow the regular old S-video Genesis/AES instructions and just only use the stuff he listed.

Edited: If I remember correctly, you really just leave out a NTE85 transistor and/or use different value resistor or two than what used to be done over the years. I guess the same applies for his Neo Geo S-video mod.

[Mathius]

@Mathius: You can actually learn how to do this stuff yourself man. No joke, there really isn't anything to it when learning how to use a solder iron and doing these mods. Just get a simple set-up and practice on a dead VCR or stereo. Once you get the hang of things and grab the concept, this is easier than changing a car tire. Reason I mention this, is due to you are really into the retro gaming hobby and I also remember you having a wavey video problem with your modded Neo Geo AES that could easily be fixed a while back.

Anywho, isn't it better to get a RGB Scart cable and convertor to component in the US? Now, that would be the best picture to go with to me. I remember something odd about the RGB color levels being different in the Genesis. Also, Xian Xi from the Neo-Geo.com forums has a slightly more correct color S-video mod than the exact Neo Geo AES mod. Here's a link to his version of the Genesis S-video mod.

edit: Look in the tutorials section/home consoles/other/Genesis 1 S-video. Notice the orange and reds being more correct on the "New S-video" mod.

The link didn't lead to where you wanted it I believe. Here is what you probably meant.

Thanks for the link but pics would have been great, and it kinda seemed like he posted it for people who weren't dumbheads like myself. What is Luma? What does Chroma mean? Where does the ribbon cable come into play?

He really laid out in detail the 1 PSU for the Model 2 Sega CD. Pics, steps, everything. I am sold on the "new" way of doing that S-vid mod as the colors are much sharper compared with the old. I just wish it was more detailed.

Look at his Neo Geo AES link which was posted earlier in this thread from SignofZeta. Those picks will be exactly the same. Turns out the mod is no different. I just never read into it until now.

Chroma is the color signal and Luma is the brightness. The ribbon cable I assume is another option by peeling each wire off it and using the wires strips individually. Better just buy rolls of 28-30 gauge wire. I suggest one red and one blue.

Here is a better link to compare the genesis s-video mod to the other.

See how the Neo Geo earlier link only uses 1 NTE 85 transistor. That is the way you want to go with. The second link (which i just posted) is to help you locate the chips and solder points used on the genesis really.

The problem with these Genesis s-video mods is that they are certainly not simple.  A circuit must be built.  Wires are going all over the place.  I don't want to send my second Genesis away to get modded because it would take forever.  And when I get it back, there's still no gauarantee that my capture card won't blow out the colors to oblivion like it does with the XMD-3 attached.  The XMD-3 is pure dogshit, by the way, unless mine is broken.

Also, am I required to install a blue LED with any mod I do to the system?  It seems like everyone who does any kind of mod has a giant hard on for blue LEDs.  Why?  They look so ghey.

I can see your point on the LEDs. But, with systems with zero power indicator lights like NEC consoles, and the Neo Geo, it's nice to be alerted to when your system is still on. I have left my Turbo on for days before I realized what I had done. My Neo would have surely suffered such a fate if it had never been modded with an LED.

[Joe Redifer]

What is the harm of leaving the system on?  I know a guy who routinely leaves his games on pause for days and days with no ill effects, even CD and DVD based systems.  You can tell when the Turbo is on because the switch reveals the bright orange when it is.  I guess you could paint one side of the Neo switch to be less tacky than an LED.  And why do they need to be blue?

[Mathius]

My gaming room has very poor lighting, so that orange doesn't pop out as well. But, every LED mod I have seen for the Turbo just doesn't look right. It's the placement I guess.

And my favorite color is blue.

This is why I prefer the solder the components onto the chips method. There is plenty of space and you don't have to build a board like the second genesis link i posted. Seriously, there are only 5 wires to fool with with the direct to chip method. You just need a wire for chroma in/out, luma in/out and ground. It really doesn't take too long and is real easy to do. The more annoying part is drilling a hole and mounting the s-video plug. I used to hate that part, but it really isn't that bad. Make sure you have a good drill bit, then use masking tape and a marker to line it up right. I suggest getting the speed and angles right with the drill by practicing on plastic junk.

This mod is really cheap in parts. I bought in small bulks to mod around 6 systems if need be. I think it came out to be like $8-$10 per system in parts. It's been a while since I fooled with all this. Hell, I haven't gotten around to the improved S-video change to my Genesis yet and my AES is NeoBitz component video modded now. I guess I will make the changes this week.

BTW, the mod should look alright using a capture card. Even the older S-video mod was used by the guy on Classic Game Room (Inecom Company) youtube channel when he does so with his genesis.

Ive noticed that most composite video cables on ebay for the genesis 1 have Only one white audio plug. Is there a composite plug for the genesis1 that offers stereo audio?

I imported one from England a few years back off of eBay I think. Try a search for "Genesis Stereo AV Cable." Most of these are custom made but shouldn't be too expensive.

[Joe Redifer]

The model 1 AV cable will only ever have mono audio as the only way to get stereo is out of the headphone jack.  For model 2s, do what Mathius suggests.

Anyway, I am trying a new version of the RGB SCART to HDMI.  Hopefully it will have fewer artifacts than the old one I tried. That way I'll be able to record the games in RGB.  I'm not sure what the Classic Game Room guy uses to record, but I have two Sony things that convert analog video into a DV stream via firewire.  I think the main problem is that the Sony just can't deal properly.  I don't want to record into MPEG 4 or any other interframe format and I can't find any DV recorders for cheap (must be DV at minimum, ProRes would be best).

As Joe Redifer mentioned, those aren't stereo cables, the cable is doing dual mono rather than stereo in that case. This is the same problem a stock Neo-Geo has, the only way to get stereo audio out is via the headphone jack or mod the system.

[Mathius]

That's why I said it's a custom cable. It has a lead running from the headphone jack back to the end of the cable. I'll take a pic and show you. It's true stereo!

This is made especially for a Model 1 Joe.

Ahh, I do that with my Neo-Geo AES. I have a headphone jack to RCA cable that gives me stereo sound.

[Joe Redifer]

I have a SCART cable like that.  You can make a cable like that for yourself with two separate cables and a roll of electrical tape.
