Cool, I don't know why they stopped updating the PSP version. I hope you get sega CD audio working eventually.
Please upload the source code (the license says you have to do it).

Yeah as on all compressed emulator eboots, roms load fast, more fps etc.
I use 99% easypbprx.exe. You can do it with your sdk too.

Could you make a version compatible with VHBL? I tried to rename the eboot but it didn't work
