Hello,

I have a Street Fighter 2 CE CPS1 pcb with accelerator part 2 romset which I would like to convert it back to a normal Street Fighter 2 CE.

It works but has vertical lines in the fighters, not in the background.

All boards are clean and have no jumper wires. B board has 4 accelerator roms (20,21,22 and 23)
I believe that the PAL chip is also not original.

I do not have the tools nor the skills to burn roms whatsover.

Is there anybody who can help me out to convert this back?

Located in Belgium.

The OP reached out to me (...thanks for the plug !),
but I've never seen a SF-II with 4 x 27c220 [2Mb] game eproms (U20, U21, U22, U23 ).

All the boards I've ever seen have 3 x 4Mb eproms (27c4096 or 27c240) , [U21,U22,U23]
not 4 x 2Mb eproms.

Even the MAME files ( Acc, Pt 2) has 4Mb files.

I have no idea how 3 x 4Mb fits on 4 x 2Mb eproms ?

And even if I ignore the math for a moment,
where would I find the SF-II CE rom files for 4 x 2Mb eproms ?

Anyone ?

Thanks,
Steph
 
Hey Steph,

Did you ever figure anything out on this one? I'm looking at one as well that has some missing sprites...just on the characters. Was going to start pulling chips and comparing to online files.

I never got more info on the 4 x 27c220 eproms .

If you have the version, I would curious to an eprom dump.

Thanks,
