As long as any software enabled digital effects with the right settings before the game is run, the glitch will probably take effect. You might have been able to get the same effect through IGR, although I haven't personally heard of such a thing happening. Not that I have been looking out for such cases on purpose. A line has to be drawn here. If you try to solve all the problems of other projects, then your project will have no limit to its scope. It's a function of the SPU2. Unlike most other IOP peripherals, this device doesn't seem to have a reset function. So a "reset" by libsd is just a software cleanup of the SPU2's state. Unfortunately, it doesn't restore everything to a clean state, like the register values related to digital effects. I made OPL do this before every game is booted, so that we won't have to waste resources in identifying and blacklisting all games with similar mistakes.
