Auto-switching Mega Drive / Genesis TMSS bypass mod
« on: August 25, 2008, 10:07:30 PM »
So yesterday night I finally finished this :D



This mod will bypass the TMSS screen (Produced by or under license from Sega enterprises ltd.), while retaining full compatibility with 32X, Mega CD and Power Base Converter. This mod also has a single switch disable function in case of trouble.

How it looks like in my MD2 :


I don't think I can make any demonstration videos for you... my web cam sucks, and so does my connection...

I just noticed a small error on the schematic (disable switch has one resistor in the wrong place...)... it won't make the mod work any different though :P
And that I have comments missing on the MD scan...
Mida sa loed ? Nagunii aru ei saa ;)

Anyone have pictures of the schematic or know of a recent topic with this same information?

old topic I know but this was interesting to me and I managed to find the original schematic via google cache. I've re-uploaded to my private server for prosperity:
