In theory, this should be workable because the SVC board is still an MVS, despite the fact that it does not accept MVS carts. The in-game BIOS operates in the same way that the original BIOS for MVS boards works.
In practice, SNK threw a curve ball here by scaling down the BIOS chip to 32 pins from 40 pins. I'm fairly certain that if the pin mappings in the Universe BIOS code were set up for SVC or if the 40-pin chip was correctly wired to a 32-pin chip (almost like a debug mod), the existing universe BIOS should work.
Question mainly to Razoola -- do you have any info on the pin mappings for the MVS BIOS? I'm most interested in unused pins... if there are at least 8, then the BIOS was simply optimzed. If not, then some of the pin functions were combined, so an MVS BIOS would require extensive changes to its code in order to work. (I would not hold my breath if that was the case.)
