Yes.

I've cycled some of these ROMS through every MAME emu by holding down the button and using the menu to set a new default Mame EMU with no luck on some if I'm not sure which version the ROM was.

This is what I'm saying is your problem. You need to start over and find a matched set for the emulator you wish to use not the other way around. Google search for a "mame2003 0.78 romset" and use it exclusively with mame2003. The link I posted earlier walks you through all of this.
