Editing 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 because sony mostly uses lua patches for the psp releases, thus, not many cli commands were needed to be 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 render many games unplayable.

== Commands ==
'''Known functions:''' Require cleanup.
<br>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'''

; Redirect host0: to a specific directory (uncomment to enable).
; By default it's mapped to either "/hostapp/" if available, or "/app0/" if "/hostapp/" is not available.
;--host="/hostapp/"
 
; To dump the original video in PMF format, uncomment the --dumpvideos line
; For example, with the current setting, it will save them in a "videos" directory inside the File Serving Directory
;--dumpvideos="host0:videos"
 
; 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
; For example, with the current setting, it will load them from the "texreplace" directory inside the File Serving Directory
--texreplace="host0:texreplace"
 
; This forces alpha blending to on for replaced textures. (uncomment to enable)
; With this we can freely make use of a normal alpha channel on replacement textures
--replacementalpha=true
 
; Antialiasing mode. SSAA4x looks best, MSAA4x only smooths edges.
; Choices: off, SSAA4x, MSAA4x
--antialias=SSAA4x
 
; Enable switching between original and replacement textures at runtime using the L3 button on a DS4 or the 'T' key on Windows
;--texswitch=true
 
; Turns on the auto-resampler. Assumes textures in texreplace are at 8x resolution and resamples them at load
