i finally made it worked and this is what i did:
Existing files
mc0:/OPL/OPNPS2LD.ELF
mc0:/OPL/BOOT.ELF (this elf is opl elf renamed to boot.elf)
mc0:/OPL/conf_opl.cfg
my exit path is mc0:/OPL/OPNPS2LD.ELF. the weird thing is if any one of the two elf in OPL folder is removed or deleted the exit path will fail. ive tried this for several games and im sure that if one of two elf is deleted (either OPLelf or BOOTelf) the exit path will not work.
is this a bug?
