Test with both Fast Interpreters first. If you get "Unimplemented" for some module function then it's dead. You can try to manually load that module using Automatic and Manual load mode to get past it, but that won't work for nearly all cases, since we already automatically load almost all loadable modules possible at the moment.

Some rare cases of games working on Recompilers but not on Interpreter exist, so you can try both Recompilers if you get some weird error on Interpreters. See: https://github.com/RPCS3/rpcs3/issues/2909

Usually the most used combinations, by order, are PPU F + SPU F, PPU R + SPU R, PPU F + SPU R if there's a problem with PPU R, PPU R + SPU F if there's a problem with SPU R.

There are known scenarios where games have glitched textures due to inaccuracies on SPU Fast comparing to SPU Precise. So if you get weird bugs you should try in SPU Precise. For example, the invisible character bug on Red Dead Redemption is solved by switching to SPU Precise. Cases were Precise Interpreters are needed are rare though.
