Hi all, have a old model 1 Sega Saturn system, and want to perform the 50/60hz mod on it, but can only find guides for the newer models (the ones with the grey round buttons, mine has the black oval ones). I have tried removing pin 79 from the GFX chip on the board, but now i do not get a picture at all when i turn the Saturn on, it didnt blow up so i guess thats a good thing! Anybody know what pin a need to solder to on the Graphics chip to get the mod to work on this older version? thanks in advance!
