Is pocketsnes the default SNES emulator for RetroPie?

If so, my only issue with it is that it doesn’t create a save file, and in some games it (for whatever reason) has trouble with layering and opacity text.

IE: In Super Mario Kart, the game puts an opacified-number noting your current place on the top of the user-space but pocketsnes renders this layer under-neath.

I don’t know why the emulator itself would be at fault, but the problem is correlative and only occurs when pocketsnes is used.

I have zero controller issues with the default retropie emulator
