According to the docs mame2003plus uses the .78 mame romset, is this correct? The patch is not working on that version. Does this hack require a newer edition that wouldn't work within Retroie?
I purposely made sure the new clone rom for ffightae would work off the original MAME78 ffight parent rom, so if you have that in your set and it's correct for MAME2003
you'd just drop fightae.zip into your roms folder and it'll work fine, i know it did for me a while back when i tested the game after adding support for it.
