so since some time you can use cheats in the PPSSPP emulator and people enable through them 60fps in games, i've recorded really short gameplay with a 60fps cheat code

it plays amazingly

here is the cheat codes, you need to enable the 60fps on obv

Code:
_S ULUS-10529
_G Phantasy Star Portable 2
_C0 60fps ON
_L 0x00630B6C 0x00000001
_L 0x20662FF4 0x42700000
_L 0x20662FF8 0x0000003C
_L 0x20662FFC 0x3F800000
_L 0x20663004 0x3F000000
_L 0x20663008 0x3C888889
_C0 60fps OFF
_L 0x00630B6C 0x00000002
_L 0x20662FF4 0x41F00000
_L 0x20662FF8 0x0000001E
_L 0x20662FFC 0x40000000
_L 0x20663004 0x3F800000
_L 0x20663008 0x3D088889
enable cheats globally in the emulator menu -> open game in the emulator -> go to cheats menu -> game will open notepad and an empty file, paste the cheat codes from the box above and hit Save -> enable the 60fps on code for the game -> enjoy

the audio desync is my recording software messing up
