I am running 5.00 M33-6 with a custom "version.txt" to trick my PSP into thinking it is 5.50.
I didn't want to go from Dark Alex' firmware to the newer GEN firmwares. This is for numerous reason.
#1.) There is PS1 issues. Some of the titles that ran flawless on the M33 firmwares now have some issues.
#2.) No 1.50 kernel patch.
These are my (2) main reasons.
One day I will upgrade, but as of right now I am fine. I can still access the PSN store thanks to my PC, so demos and stuff are still accessible.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
