PSPHD

The new PS Plus PSP emulator 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 as the ps2 emulator due to the existence of an unofficial PPSSPP core in the unofficial Retroarch port for the PS4. As far as the compatibility and performance go, the Retroarch core is yet to be bested. This 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.

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.

CLI commands

These commands can be added to any of these files:

  • config-title.txt
  • package-ps4.conf

Emulators

Every emulator is programmed in a differently. 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.

Memory mapping


Note: The memory on PPSSPP is 0x4000 offsets ahead of the memory on the PS4

Size Offset From -> Offset To Name
1008000000 -> 10887FFFFF Allegrex memory(?)
640.00MB 228200000 -> 250200000
64.00MB 250200000 -> 254200000
32.00MB 254200000 -> 256200000
2048.00MB 256200000 -> 2d6200000
16.00MB 2d6200000 -> 2d7200000

Registers map


Registers that are marked with (?) are untested but should be accurate.
*Note: The offsets' positions change as the CLI file's content increases, but the offsets should still be somewhere nearby the offsets listed below and the layout should be the same regardless. The PC pointer script can be used to locate another PC register properly in Echochrome's emulator

;--host="/hostapp/"
 
; To dump the original video in PMF format, uncomment the --dumpvideos line

; To dump the original audio in Atrac3 format, uncomment the --dumpaudio line
; For example, with the current setting, it will save them in a "audio" directory inside the File Serving Directory
;--dumpaudio="host0:audio"
 
; To replace atrac3 audio samples, use this.
--samplereplace="host0:samplereplace"
 
; To save the in-game textures as the game runs, uncomment the --texsave line
; For example, with the current setting, it will save them in a "texdump" directory inside the File Serving Directory
;--texsave="host0:texdump"
;--texmissingsave="host0:texdump"
 
; To replace specific textures as the game runs, uncomment the --texreplace line
