A new custom firmware has recently surfaced and - guess what? - it isn't from Dark AleX. Homebrew developer Yellow_Rain dropped by the QJ.NET PSP Development forum and informed us that a new custom firmware based on the 3.90 M33 build can now be downloaded and installed into your PlayStation Portable.
This unofficial patch, based on the most recent custom firmware released by Dark AleX, contains a reversed and updated popcorn.prx. Also, a hex-edited vshctrl.prx and a new GetVersion opcode were both updated in this new build.
The developer has tested and confirmed that CFW 3.93 M33 works for both the classic and Slim PSP. Please take note that it only flashes the changed modules, so make sure that you have CFW 3.90 M33-2 installed on your handheld before running the patch.
To give you a better idea of how to install this new custom firmware into your handheld, here's a video showing off the installation process. As always, make sure to thoroughly read the documentation included in the program before installing it.
