Homebrew developers Xenogears and Becus25 have released a utility dubbed Custom Firmware Enabler. As its name implies, this allows users to enable certain M33 functions from within the ChickHEN environment on firmware 5.03.

That said, it’s not quite a full-blown implemention of Dark_AleX’s M33 firmware, but comes close: all features remain intact apart from the built-in recovery menu and support for homemade PSOne rips. Users should take note that while files are written to flash memory during the installation process, nothing is actually overwritten, meaning there is very little risk involved.

Since installation is not permanent, the application must be run again after reboot in order to enable M33 functions. Compatibility extends to nearly all PSP motherboards, including the TA-088 v3. However, PSP-3000 units are not yet supported.
