I'm not completely certain, personally... for the formats that I definitely can't play on the computer, the MP3s will have to do. The format that I trust the least despite being able to play it... kind of... is the MIDI format due to sheer inconsistency. I failed to vote on one AY entry (somehow the .sndh file failed to load on Audio Overload), all three HES entries (all three .vgm files struck out, failing to play on Audio Overload, apparently being made in Deflemask, which explains the format), all Mario Paint entries, all Adlib entries (I could have used DOSBox, but I think I'll just stick with the MP3s, as playback stinks on my end), and all .sapx2 entries (I was hesitant due to knowing that this was a music hack, though I just tested one... and they work in stereo mode on Audio Overload, so at least I can go for it...)... plus, on the SPC files, on the few MP3s that I heard, for at least one of them I thought I heard the .wav to .mp3 exports from the source module files...
