I can run it in version 2.0, but it failed in version 2.1

Same ROM, same system, same syntax
in 2.1 “Identification of MusicPlayer2000 driver is incomplete.”I'm confused
Anyway, thank you

Which game caused the problem?　I assume it was caused unexpectedly by a change in the detection pattern.

pokemon LeafGreen

I see. Since Pokémon does not use vanilla MP2K, it makes sense that its detection would not work exceptionally well.

Using Saptapper 2.0 is a legitimate workaround. It does not produce a different GSF than Saptapper 2.1. I apologize for the inconvenience.

It doesn't matter, your plug-in is a big help! Thank you
