Das Boot: un-hacking

So, quick question. I have a boot that's also been hacked. It has all EPROMS inside, and all of them are socketed. The game seems to be the same, except hacked to unlock all characters and change the power meters up. So that means P1 is probably the only rom that's altered from the originals. So if I replace P1 with an original (not happening) or a duplicate it should be un-hacked again, right? See, I have the UV eraser and the eprom writer, so I figure there's no reason why I shouldn't just change it back. Thoughts?

yes replacing p1 will probly be all you need to make it working.

but i would dumps each eprom and crc check each to the current mame set of roms
