Try it on bsnes/higan, snes9x probably wants the rom to be expanded or the size byte of the rom info set larger.
Headered ROM, IPS hardpatched, BSNES+ v073u1: Hangs after choosing Cody.
No header ROM, IPS hardpatched, BSNES+ v073u1:
Working. Starts with 2 players.
Headered ROM, IPS hardpatched, Higan 106: Hangs after choosing Cody.
No header ROM, IPS hardpatched, Higan 106:
Working. Starts with 2 players.
Headered ROM, IPS hardpatched, Snes9x 1.58: Hangs after choosing Cody.
No header ROM, IPS hardpatched, Snes9x 1.58: Shows some purple lines for a few seconds, nothing after it.
Or you can try adding this to the asm file:
org $3fffff
db $00
Okey, so i added those two lines at line 81, injected the asm file with xkas and:
BSNES+ v073u1 & Higan 106 / Headered:
Hangs at black screen, does not load.
BSNES+ v073u1 & Higan 106 / No header:
Working. Starts with 2 players.
Snes9x 1.58 / Headered:
It restarts the game to the intro, if you try again, after pressing start at the main screen, it hangs.
Snes9x 1.58 / No header:
Hangs at black screen, does not load.
