The PSP emulator for PlayStation 4 includes plenty of undiscovered functionalities. It even allows patches directly to the emulated Allegrex CPU. Not many CLI commands were added this time around. Very few commands have a description to their usage inside of the eboot.bin, everything else is just guesswork from the scene. Plenty of Lua commands need to be understood before the compatibility of games can improve. The PSP emulator has not gained the same popularity in the scene as the PS2 emulator due to the existence of an unofficial PPSSPP core in the unofficial Retroarch port for hacked PS4. As far as the compatibility and performance go, the Retroarch core is yet to be bested. This official emulator may hold potential, but the potential can only go so far as it seems not to have support for gamedata installation, which in turn will render many games unplayable. | The PSP emulator for PlayStation 4 includes plenty of undiscovered functionalities.
