Ok. im not sure if i get in on how to install a custom firmware on the psp. I have been looking on dark alex's homepage and a lot of places on the net. heres what i have confusion on. btw i have the official sony 3.71 firmware on a fat psp currently. is there any thing i would need to add or do when i am installing the 3.71 custom firmware? would i need to install any previous versions of the firmware? Or would i need an official firmware file to install the custom? it says in the "3.71M33.rar txt file this.... ------------ Requeriments: a fat psp slim with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won't work, due to a bug that affects them and OE; or a psp slim with 3.60 M33. ------------- that is where that confusion comes in about if i have to install another custom firmware on top on my official 3.71. ------------------------- Also, it says: make sure you have configured the psp to run the game folder in the 3.XX kernel. What does that mean? How do i go about doing all of this to install the 3.71 custom firmware. Please do not link to other websites or forum posts. im confused enough already. Help would be much appreciated. How do you update the firmware as well?
