A new version of fMSX-PSP has been released. New in this version is a bugfix for FMPAC/MSX Music: corrected MSX Music/MSX Audio labeling in System settings - MSX Music now correctly refers to the FM-PAC/YM2413 chip; MSX-Audio refers to the Y8950 chip. If the emulator was previously freezing with FM-PAC audio, double-check to make sure MSX-Music is enabled (disable MSX-Audio to gain some extra speed) and try again.
