ok well after listening to the numen demo just for kicks I quickly compiled a version of atarixlbox with the new_pokey code from foft, the creator of the GP2x port. It sounded pretty ok so I'm thinking of going with that, thus reducing the number of sound options to pick from. It even manages to make it through Ghostbusters without crashing.

Slapped the player/missile/playfield collision cheats in tonight, hopefully it will compile later without any big isssues. If it works well enough then I will use that as a release candidate for testing. I wanna test one last thing related to the rewind function as well.
