Golden axe mask roms

[Shinydaz]

Does anyone know how I can read these 6 mask roms(right), what size they are, not done much sega stuff? Or what I can replace them with? 27c2001?

Thanks

I think you might need to use d27c020, or the same type as those NEC ones.

Thanks, I reprogrammed some but unfortunately still no sprites, will have to dig further.

Is the battery Ok ?

Have you set the jumpers to use normal roms instead of the mask roms

27c2001 or 27c020 are fine,just change the jumpers,like this:
