Awesome nice version, but 32X emulation is too slow, well you can't ask too much to the nice old PSP, keep the nice job!

For me, any 32x rom run very slow, set frameskip to 0, try all 32x renderers, no bios is need. Reducing SH2 cycles you gain any speed, however, will be playable only if a dynarec is implemented

Do you have any future plan for implement dynarec with 32X? (Retroarch does with picodrive in their port for android).

I have not decided yet, but if I try, it will be slow. Picodrive has this dynarec for arm since old versions

The collision detection doesn't work on Star Wars for the Master System.

This is a common flaw present in every single Master System emulator (MasterBoy, SMS Plus, e[mulator], MMS Plus, PSP Master) for PSP for this game.

Can it be fixed?

Yes, it can be fixed. This error is in the z80 core I think. Difficult to locate. My work in this emulator was to port version 1.91 to the PSP and implement the SVP dynarec. For now I'm taking a break to go on with life. If I go back to work on this project, it will be in the SH2 recompiler. But the code is open and anyone can contribute. Best regards.
