PSP Emulation

PSPHD

The new ps plus psp emulator has a lot of undiscovered functionalities. It even allows patches directly to the emulated Allegrex cpu. Sadly sony has not made it easy for users to use CLI commands. Since sony mostly uses lua patches for the psp releases, not many cli commands were added. Very few commands have a description to their usage inside of the eboot.bin. Everything else is just guesswork from the scene. The psp emulator has not gained the same popularity as the ps2 emulator because currently, there is an unofficial PPSSPP core in the unofficial retroarch port for the ps4. and as far as the compatibility and performance goes, the retroarch core is second to no one. This emulator may still hold potential, though sadly it does not seem to have support for gamedata installation. and that has led to many games becoming currently unusable. with an official retroarch release coming into ps4's way it seems delving deeper into the PSPHD emulator and the PS1's new psplus emulator is pretty useless.

Commands

Known functions: Require cleanup.
The rest of the cli and lua commands can all be found inside of an emu's decrypted eboot.bin.

Emulators

Every emulator is programmed in a different way, sometimes choosing the right emulator is the only possible way to fix a game. Emulators are not provided pre-installed on the ps4, they have to be unpacked from a backup that's downloaded from the ps store from that specific game. this list includes The typical usage of some of The emulators.
