This is a pack of music ported and SFXs ripped from Super Mario World 2: Yoshi's Island which includes a total of 45 songs ready to be inserted and 127 SFXs ready to be used with AMK! The pack includes all original songs from the original game and Super Mario Advance 3. In terms of SFX it should include most single channel SFXs from the game with the exception of some which are hardcoded in the SPC engine. Some examples of this include multichannel SFX as well as some that were causing problems despite the data being set right which needs further attention. Some SFX also sound slightly off tune bc YI's SFX instruments follow the same format as regular song instruments which have a subtuning multiplier which SMW does not have.
I'm confused about the "no intro" versions. Wouldn't this mean the music goes right to the boss theme, missing the first few seconds of the build up to the main song? Or does "no intro" means something else I'm not understanding?
