i have two problems with my two different i/o boards.
one, i have the capcom i/o. everything works fine, i use it all the time with power stone, ggxx#r, and cvs:pro. when i try to play virtua tennis (GD), the game will give me a jamma i/o error, but not always immediately. sometimes it wont get an error but then no controls will work and the test menu will say no i/o. anyone have any ideas?
i also have the original sega jamma i/o (the little pcb.) it works fine with virtua tennis but the video is really bad. its washed out, flickery, and all around kinda shitty. anyone have any idea what thats about? ive only got the jamma edge connected. i noticed theres a few other connectors, does it need more power?
im using a naomi 1 mobo with japanese bios. the i/o boards are powered by a regular jamma psu. the naomi and gdrom are powered by a sun psu.
