Same Same Same! 1 player rom question

[exidy]

Im going to convert my 2 player Fire Shark to a 1 player (Same Same Same!).
Wondering if someone can tell me what types of roms are being used on a Same Same Same at Rom locations 9-12.

im assuming 9 and 10 are 27256
and 11 and 12 are TC571001D?

thanks in advance,

Looks like ill need to purchase TC571001D eproms because I cannot find a crossover for it.

You should be able to read those roms as 27C010 and check them vs. the mame dumps.
Aka.. 27C1001 = 27C010

If I remember right, the TC571001 is equivalent to 27C301/27C1000 non-jedec.

Get ready for an ass-kicking, in a good way .

Yes, 27C301 is what you want to use to replace those chips with the non-JEDEC/mask rom pinouts.
I also converted my 2P version to the 1P version.

ok, so I tried both 27C1001 & 27C010 and neither worked. So I ordered some original TC571001D's and it worked fine.
