Patched ROM JP900CW or real ROM Anonymous 09/15/25 (Mon) 06:36:33 No.21 [Reply]

Hello guys, just asking, does someone here have a patched fx-JP900CW emu ROM or a Real ROM? If yes I would like to know. Thanks (note: the photo is not mine, it's from the internet.)

I do have a real ROM, but it's not mine. Most ROMs nowadays are held by private collectors, so it's quite hard to get a hold of them.

Hello everyone, just asking, since ROM sharing is allowed here, does anybody have a 570EX CY-234 VerF real ROM?

Anonymous ## Mod 08/10/25 (Sun) 08:05:00 No.18

I do (it's CY-235 fx-991EX, but the 2 models have pretty much identical ROMs), but the ROM's not mine, and I don't think its owner would be happy if I share it here.
