Old Roms not Running on Latest Version...

Hey guys, I just dusted off my old Zinc Emu and decided to get the latest version to see what's in the new edition. It was running fine with the old rom set, and then when I tried running them in the latest version, nothin...

Did they change the format? or do they just require additional files since the update?

The last update for ZiNc was several years ago, you know. Anyway, yes, the ROMs changed for some games over time.
