How does this work for STGCustom stages? Like if you only wanted to have a few of them have the ASL code, do you have to make every custom stage have an _A & _B at the end of their filenames? Cause that would be troublesome..
Yeah, that's how it works, and it is troublesome indeed. Specially cause as they don't exist in the iso, and if one of the files is missing (for example, you have no STGCUSTOM09_B.pac), the game will freeze when trying to load it cause there's no stage in the disc.
Anyway, a bat file could easily rename all your stgcustoms so they're all split in _A and _B versions, so you only need to replace the _B ones with new stages.
