Sound effect replacements

[[Unknown]]

Well, everyone keeps answering "Yes, I would like to replace music." Music is the thing that wouldn't get replaced, at least in the vast majority of games. That you'd need to edit the ISO and potentially game code for.

I don't really relish the idea of tons of "Music replacement not working" complaints, issues, threads, etc. I realize it's confusing that there are two completely different subsystems for playing audio.

You can check your favorite game - watch the Debug Log. If it says "sceAtrac" anywhere in the log, you're virtually guaranteed that any music/voices cannot be replaced simply. In some cases you'll have to edit game code to change it (for example, in Trails in the Sky, this would be true iirc.)

VAG is used for short sound effects - that's why replacing can work. All of the sound effect is in memory at once. This is not true of music and voices, which are often "streamed", like Pandora (from the emulator's perspective, it might be coming from the UMD, the internet, anywhere - it's just streaming.) Pandora makes replacing things hard.

A very small number of games use VAG for music - I think they are ALL ports of PS1 games. It is very unlikely the game you want to replace music in uses VAG for music.
