I need some help getting this board going again. I messed up one of the EPROMs and need to reprogramed it however it seems to be running a non standard rom set. I thought it would be as simple as dumping the roms and figuring out what rom set it has and reprograming the missing rom. My rom set is not in the rom-ident database. The board is completely working and will work again if I can find the bin file for the missing 3A EPROM. My set is running the 91635b-2 B board and 92641C-1 C board. The C board had a wire soldered to it bridging 2 pins. I think this has something do do with removing the battery.

What do I need to do to get this running again? i don't mind re-flashing all the EPROMs with a standard rom set but I don't think that is an option.
 
Hi aapuzzo,

Please, can you post a picture of your ROMset to check crc32 ?
 
That's what it is. Mine is the US or english version. I used the 01 rom from the set in the post below. I will say that my crcs didn't match all of the roms in the sf89_chr.rar file probably because that one was Japanese but since it matched one of them I figured it couldn't hurt to try it.. I crossed my fingers and hoped my missing 1 rom would work with what came in this set and it did. I played through the game and it was all in English and I didn't notice anything wrong. I can't guarentee that its the original file but it did work. I can add my files to that post if anybody wants them.

One thing I will add is I did reach out to HKLegends and they responded back saying they don't have the rom but will try to get one from the manufacturer and mail it to me.

Thread 'Final fight (900112 japan) for B21 C-Board'

sup.
i bought a final fight b+c board from aliexpress. it comes with B21 C-Board. so, according with the recommendation of our great @Hammy , i am here to share.
B-Board is the same used for SF2CE.
feel free to move/delete if this stuff is already present in the forum.
i want to still buying stuff like this in the future, so, glad to share AEX B21 conversions in the future.
hope its useful for someone.
and please let me know if roms are allowed here, otherwise, i will make IPSs if necessary.

May be a tricky one! If the ROM set isn't in the database, you might need to dig deeper into the specific revisions or check if anyone’s had a similar setup. I’d recommend reaching out to others who’ve worked with the 91635b-2 and 92641C-1 boards for any leads on that 3A EPROM. Re-flashing could be an option, but I get why you'd want to avoid it.

This is what I got below. Unless I labeled the files wrong my 2 and 3 roms are swapped from that set. I did not realize this at the time because I didn't display the CRCs all at once. Does the order matter for those 4? I just noticed the 4 rom was the same and figured, "what the hell, why not try 1 from that set?". It seems like my English version definitely has different ROMs in some of the other slots which makes sense. They can't all be identical.

Just to note my 1-3a.bin file below was taken from the Japanese set and not dumped by me. Based on what I see now I'm almost positive i got what I needed from that set. I got lucky that it wasn't a rom unique to the English version. I can share my set somewhere if anybody wants it.
