Hey everyone,
I have a few extra Genesis systems laying around and I've been thinking about doing a little modifying work on them. I also want to get into doing custom paint jobs on them as I haven't really seen any good pictures of classic retro systems with cool paint jobs. Thinking a metallic blue with Sonic Team and Sonic Logos on the controllers would look sweet

Anyways, I'm looking to see if anyone here knows of good websites or tutorials that could help me through some of the simple modifications that can be done on the system. Such as adding A/V & S-Video inputs, region/language switches, 50/60hz switch, widening the cartridge slot, and other little things like that. I've been doing several google searches but coming up with nothing, only a few websites that offer sales of modifications and a few message boards. Any help would be appreciated.

Also, if you know of any good custom paint websites that feature classic systems, let me know. I'd be interested in taking a look.
