PSP Homebrew Support
Epinephrine support launching unsigned homebrew applications directly from the XMB/VSH, and loading plugins with a powerful configuration format.
All user-mode PSP homebrew since PSP Firmware (FW) 3.71 onwards should work fine. Kernel-mode PSP homebrew, on the other hand, may require a build specifically targeted to PSP firmware 6.60 or 6.61 to work on Epinephrine.
Homebrew Apps
PSP homebrew applications are custom software created by the community that can run on the PSP hardware, ranging from games, emulators, and utilities (like media players and file managers).
Homebrew applications must be live on ???0:/pspemu/PSP/GAME/ directory to appear in the XMB/VSH.
Homebrew plugins
Homebrew plugins are programs in the form of PRX files that can add extra features and/or modify the behavior of the PSP system and games.
Homebrew plugins .prx files must be put in the ???0:/pspemu/seplugins/ folder and be added to the configuration file ???0:/pspemu/seplugins/plugins.txt or ???0:/pspemu/seplugins/EPIplugins.txt.
info
PSP filepaths are case insensitive. For that reason, files and directories inside the Vita/PSTV ???0:/pspemu/ directory can be all uppercase letters, lowercase letters, or a mix, and it will work normally.
So don’t worry if you find variations in paths like /SEPLUGINS/plugins.txt, or even crazy paths like /SePlUgInS/pLuGiNs.TxT.
The following pages provide more detailed information on plugins.
Legacy 1.50 Homebrew

what do i do if my legacy 1.50 homebrew fails to run?
