Request: .pnach file for disabling BGM in Klonoa 2: Lunatea's Veil

[Heroton]

I've seen posts here and there about being able to apply a .pnach that disables BGM in certain games, does one exist for Klonoa 2? And if not, how does one go about making one?

I'd love to disable voices too (Trying to record an fandub of the game), but I'd settle for just having the BGM muted.

Anyone that can help would be appreciated! ^^
