How to test games to help things get fixed

[[Unknown]]

Well, if you know Ruby, I'd recommend just trying to get into it and see where you land. The pspautotests are very simple and self contained.

That said, I'd start by trying to understand JpcspTrace, and using it on a game or to. For example, the default config just watches for sceKernelThreadCreate and sceUtilitySavedataInitStart iirc, and you can look at the log and see how that works. Just being able to trace the calls and compare with the log in the emulator can already really help find bugs and problems making games not work right.
