Having one of everyone's favortie demul issues

Meh demul can’t find ggxxac.bin.
I just don’t have it, although it prob should have come with the rom.
Help please. I must grand viper all the things.
edit to title in post since srk took away that nice ability: favorite

the only thing in my rom file is ggxxac.bin and it works fine, i suggest google since i dont believe rom discussions or trading is allowed on srk

do you just rename it?
if not ill go fetch it.
also srk
i am crazy enough to buy a ggxxac rom if i can, would be great on an astro city or something.
