HatefulGravey Posted June 1, 2011 Share Posted June 1, 2011 I know the information to get this done is out there but I'll be damned if I can find it. Anyone know of a good site with clear pictures for the right points on the board to get this done? I would love to do this tonight, but I can't find what I need.

YAGRS Posted June 1, 2011 Share Posted June 1, 2011 (edited) I looked through my bookmarks for the site from where I got my instructions, but it isn't there anymore. Looks like it was on an educational site, so it may have been a student's page that got shut down. Unfortunately, I didn't save the instructions locally. The composite mod I did is incredibly easy to do. I just don't know what points to tell you to solder to without having my Genesis open. Edit: Seems like everyone does videos now instead of just writing text tutorials with pics. Unfortunately, most seem to like to talk a lot before they get to the actual mod. Anyway, I pulled some pics from one of these videos. The pics show the pinout for the DIN along with wires soldered onto the bottom of the motherboard. The problem is that I believe this person is working on a Mega Drive, even though the video said it was for a Genesis. The reason I mention this is that the board looks a little different from mine. As for the audio, you probably know you need to solder to the headphone jack for stereo. Before I go into this, note that I am doing this from memory (just had my Genesis apart a few days ago). If you lift up the headphone jack, you should see the points where it attaches to the board numbered 1, 2, and 3. I believe one is ground, two is right, and three is left. I would verify this prior to making your connections, though. I don't know if this helps at all, but this is the best I can do tonight.

HatefulGravey Posted June 1, 2011 Author Share Posted June 1, 2011 I got video working and then found out I don't have the proper drill bit. I leave town for the rest of the week for work so it will be the weekend before anything else gets touched. This was a big help and I did read a few helpful tips around but nothing solid on the sound yet. Hopefully things will be clearing by the weekend. All smartphone for me from here out to get my answers this should be fun. Quote Link to comment Share on other sites More sharing options...

HatefulGravey Posted June 1, 2011 Author Share Posted June 1, 2011 Thats a PAL system and the difference are such that I can't be sure that would all work right for me. Thanks for the videos I did learn from them, but I can't be sure enough to do that. Quote Link to comment Share on other sites More sharing options...
thgill Posted June 1, 2011 Share Posted June 1, 2011 While I like Damomonsters Youtube videos, I disagree with where he recommends to pull audio from. He suggests pulling it straight from the Yamaha sound chip. Many folks have tried this and it appears that the audio is far below line level and would need some kind of inline amplifier to bring it up close to line level. I suggest pulling it from the headphone jack. Set the volume slider to about 7 or 8 and your audio is just fine. Here are a couple pics I use when I tap the audio on a model 1 Genesis. Not my pictures, but I have used them and they work fine. Quote Link to comment Share on other sites More sharing options...
YAGRS Posted June 3, 2011 Share Posted June 3, 2011 Those are the points I soldered to on my model 1 Genesis, and mine works fine as well. Just make sure that if you use those points for your audio, you use the volume control on the Genesis. I had my Genesis together and hooked it up to the TV, but I had no audio. It wasn't until I had it apart again to check my connections that I realized that my volume control had been set all of the way down.

HatefulGravey Posted June 4, 2011 Author Share Posted June 4, 2011 Has anyone ever seen something like this done with a 32x? It will be another week before I'm back home to finish this project up, and I feel certain I'll get it done right with all this info here. However, while thinking of this I am wondering about AV outs on the 32x as well. Its a sickness, when you start with standard AV outs everything must have them! Thanks for the info. I can't wait to get this done. Quote Link to comment Share on other sites More sharing options...
HatefulGravey Posted June 21, 2011 Author Share Posted June 21, 2011 Just to update folks, its took me forever to get to it but I have it working and I'm very happy with the mod. I should have done this a long time ago. Quote Link to comment Share on other sites More sharing options...
gredde Posted February 15, 2015 Share Posted February 15, 2015 Hey anybody, I am modding an SG for a friend and looked up tutorials (some on this thread) and everything works great except I get this cycling rainbow effect for the video. Anything that is colored will cycle through the spectrum. Anybody know what's going on? Quote Link to comment Share on other sites More sharing options...
Papa Posted February 16, 2015 Share Posted February 16, 2015 (edited) Mushrooms? Here's how to make a JAMMADRIVE out of one..(with halt button and 14 MHz switch) ..and here's a direct link to click through a couple more pics of the process.. http://i1176.photobucket.com/albums/x323/Papa761203/1503986_502068886573226_1984801343_n.jpg clicking right will show the back and the kitty.. clicking left will show the end results and then the installation. We wired 6-button controllers directly into the Happ joysticks and buttons.. Edited February 16, 2015 by Papa Quote Link to comment Share on other sites More sharing options...
