I've been looking for information on how to do this the last couple days and can only find threads that lead to broken links of schematics. Does anyone happen to have a schematic of this? Thanks.
All I can say is to get on Sega16 or even here and send TmEE a message. He goes by the same name both here and on Sega16. TmEE is the one who did it. He may still have the schematic somewhere.
No, I just really hate that screen. TMEE PM'd me, if anyone's interested there's handwritten schematic.
