Yeah i think now best thing to do is try the romboard on a known good main board.
Send a pic of your mainboard too! Maybe it's a missmatch...

I also have this arena toshiden 2 according to the sticker on the top board , but the EPROMs read as street fighter ex so I guess someone converted it with those flash chips? The top board with the socket empty has that bigger Actel chip going there (have it laying beside it)

Yep that looks correct!
Does IC353 say -54 on the chip?
Yeah that's a bootleg conversion , would of been a toshinden originally.
Is this one also non-working?
Probably a good candidate for bios board
The 2nd VRAM is clearly added on too

-54 beastorizer gives me a blue screen but no code, with the bootleg top it gives me a code
Bootleg bottom board just boots to black without a top board

COH1002C is not compatible with capcom games.
I think the motherboard is fine here, but there's a top board fault
i think the black screen bottom board will have other issues
The top board maybe alright ...
.....
Swap IC's 652 and 353 from the capcom motherboard onto the raizing board
Then try the capcom top board with it... Probably it will run...
(put the DIP chip in socket)
If not, remove them chip carriers and burn all the roms with 322's from the mame set and try again
If not, i could do a "lame patch" so you can remove that actel thingy

This should leave you with the faulty raizing top board and faulty motherboard (and a couple of loose chips)
I would not do any more to the raizing top board for now, best to wait until i have tested the mach dumps.
Debugging the motherboard, usually looking for bad solder joints, scratches etc to start with
