| Many have asked how to downgrade psp this is | | | | will be needed to run homebrew games is a |
| something that can be done with any version | | | | large memory stick and also a computer. The |
| except the 2.05 and the 2.50. These have been | | | | files that need to be obtained can be |
| set up with no current means to be | | | | downloaded from the internet directly into |
| downgraded. This means that only the 1.51 and | | | | the psp using an USB port and having the |
| the 1.52 version can be downgraded to the | | | | computer utilize the psp as a detachable |
| 1.50 version. The original version is the | | | | media. This means that the files can be |
| 1.0, this version is one that will not run | | | | placed directly from the PC to the psp.In the |
| all the homebrew games that have been in the | | | | memory stick create a folder path that is |
| internet.This full downgrade of psp to a | | | | PSPGame as this is where the homebrews will |
| version that can play the games is to set | | | | be saved. Each game should have 2 respective |
| them to a 1.50 version. Since it can only be | | | | folders that will house the games and the |
| done for two version, it is required to know | | | | 1.50 hack boot up. For example, Doom would be |
| the version of the psp when you purchase | | | | loaded as two folders that would contain all |
| this. That can be easily learned by checking | | | | the files these would be Doom and Doom% . The |
| the package that the psp is purchased | | | | Doom folder will house all the boot up files |
| in.Please consider that the firmware of the | | | | that will be needed to get the psp to load as |
| 1.51, 1.52, and the 2.0 was set up to be | | | | a 1.50 and the Doom% will contain the game |
| downgradable to a version of psp that can | | | | itself. This is done but turning the psp off |
| support the homebrew games. The one that can | | | | and off and hitting the O and the X |
| perform the best with this is the 2.0. The | | | | buttons.There are two files that are needed |
| 2.05 and the 2.50 are never expected to be | | | | to run the homebrew games properly and make |
| capable of being downgraded since they have | | | | it possible for multiple games to be loaded |
| the firmware altered to make such things | | | | onto one memory stick. These files are Umd |
| impossible.The first thing to know is what | | | | Emulator 0.8c and also Devhook 0.22 as these |
| homebrew is. This is a name for the custom | | | | will make the emulators readable and the |
| designing that has been done by programmers | | | | bootup process accepted by the firmware. |
| that have made not just portable games that | | | | Without these two files the folder above are |
| can be played on the psp, but also emulators | | | | just junk. These will help discern what the |
| that can make it possible to play Super NES, | | | | folders are and also how to access the files |
| NES, Mega Drive, Master System, Amiga, | | | | that are within them.This has been a tested |
| NeoGeo, SCUMMVM, Gameboy, and other game | | | | means that has been proven to be not only |
| roms. This makes the psp able to support a | | | | useful, but also capable of running various |
| huge arsenal of games that are not normally | | | | game platforms on the psp. This gives the psp |
| available to the psp and also many of the | | | | an advantage that all of the other portable |
| homebrew additions make these games play at | | | | game consoles are sorely lacking.Dylan Graves |
