SLROM trouble
by on (#29209)
I am having trouble with making repros using the SLROM boards. Anytime i use a board SLROM 1-5, the graphics are garbled (you can hear music and advance the screen, but it always stays this way). But when i use a SLROM-6 board, the games always work perfectly. this has happened at least 5 or 6 times. Does it matter that the eproms touch each other, because they do on the 1-5 boards, but not on the 6 board.

I played dozens of SLROM games on my old Stealth SLROM devcart if that helps.

but the sockets are plastic right? i am thinking the eproms touching is messing up the graphics, but who knows.

Maybe it has something to do with MMC1 revision ??
Else the only difference between board revisions is the routing I guess.
