I've searched the forum for this and I've found a few topics about dual-booting firmwares. I wanted to know if the following was possible (I know what IS possible but I want to know if the way I want it to work will work).
-Firmware 3.03 OE-C Installed on the PSP.
-Hold L to boot alternate firmware at start (Through DevHook it seems, is there another way?)
-I want the alternate firmware to be either 3.40, 3.50, or 3.30 OE, 3.40 OE.
When holding L I want it to work as the recovery mode works...it pretty much only takes 3 seconds to boot into recovery, I expect the same for an alternate firmware.
Is this possible?
