Play it with the original Soundtrack
The N. Sane Patcher allows you to play the Crash Bandicoot N. Sane Trilogy with it's original Soundtrack from the PlayStation 1 or the pre-console version. It also allows you to revert to the N. Sane Trilogy soundtrack.
Things you should know
You can select each level that you want to patch separately or patch everything at once. If you install the pre-console version, any track that is not available as a pre-console version will be left unaltered.
Patching takes a while due to the nature of the game files, expect about 20 seconds for each level. That means patching all three games will take 25-30 minutes. This is because each time the whole level has to be extracted and then repacked.
The PSX tracks have a higher quality than the pre-console tracks.
A few pre-console tracks don't loop correctly because they are too long. There's nothing we can really do about it.
If you're using the pre-console mixes, it's recommended to set the music volume to 10 and Speech/SFX volume to 7-8 for the best experience.
