SF2 World Warrior - Tested good but non-booting rom set
I've got a SF2 WW B board that I thought was bad, but then swapped in the game roms (roms 28-31, 35-38) from a known good game, and it works fine. I take the roms off the B board that was not booting, and a known good SF2 WW set will not boot with them installed.
The roms are all labeled SF2U: 28D, 29B, 30D, 31D, 35D, 36B, 37D and 38D. Note all are "D" except 29B and 36B.
I tested the roms and they all test good and pass verification, against the MAME sets.
The roms all appear to be factory original, with original capcom labeling. Removing two of the labels to reprogram the roms noted below confirmed that they are original.
Recently experimenting with some CPS-2 games, they produce the same result that I'm experiencing here, when roms are mis-matched - no boot, black screen - so I suspected this as the cause with this SF2 set as well.
I referenced this page to try to determine if maybe some roms had been mis-matched:
http://www.solvalou.com/subpage/arcade_roms/S/sf2
That page notes that 29 and 36 (the only "non-D" roms in the set) should be sf2_29a and sf2_36a. So, I reprogrammed these two with the only "a" roms I could find, which were files sf2u_29a and sf2u_36a.
Still no joy.
Next suggestions? I'm assuming I will need to program all 8 roms and just start over fresh. But is there potentially something else causing this issue? Were all other chips on these boards identical between all versions (PAL's, SF2-xM's, etc)?
I have to start fresh by reprogramming all 8 roms, I'd like to update the set to the final US release - 910522 rev. I. Where can I get a complete rom set, with all 8 rom files?
