Dark-Alex has released TimeMachine 0.1 a program to load previous firmware and custom firmware from memory stick using Pandora. Like devhook, but working through Pandora and custom IPL's, it would work even if the flash and NAND IPL of the machine is destroyed. The timemachine is useful to run software that is not supported anymore, and also as a way of booting PSP's even if the internal firmware is destroyed. It can also be useful for developers to test their homebrew in different firmwares. To download and get more information go to DCEMU.
