Rom burning question

[KalessinDB]

While hunting for things for my 6p X-Men machine, I stumbled on free play roms for it. Slight problem though: every other time I've needed to have roms burned, the instructions have come with what they should be put on, and these are just 2 files with no real info. Now I'm sure this is an absolutely simple answer, but can anyone tell me what I should have buyicnow burn these on to?

Thanks all.

As you can see here, the 2 files 18G and 18J are mask roms of 1Mbit (128Kbytes) in size.

I'm pretty sure that they are equivalent to 27c1001 or 27c010.

Maybe someone who has already tried that can confirm.

128kb (1mbit=128kbytes) files are going on 27c1001/27c010 or non-jedec 27c1000. But I don't think that board uses non-jedec, so 27c1001/27c010.
