PSP Custom Firmware Guides

I am a PSP owner, but I always feel restricted by the small amount of good applications that exist for the PSP. More over many are very expensive, so I rather not buy them. Luckily there is a simple solution: homebrew applications. These applications are created for free by different developers and posted on the internet. However the official SONY firmware does not run them, so you need to flash your PSP to run a modified firmware. This can be a complicated process, but I have decided to simplify it by writing a guide for every release. The guides are for Dark_Alex’s M33 custom firmware, which is the one I use. This is also the most popular CFW and is the most supported by the homebrew community.

I write a new guide everytime there is a new release. The old ones exist for historical purposes, because sometimes you need to install a older version of CFW before you can get the newer one.

There are few other guides that I have written for the PSP, and the following is the list of them. They are simple tips and tricks to get the most out of your favorite handheld gaming console.

    I just got Kingdom Hearts BBS yesterday, and apparently it needs PSP ver. 6.20 or higher to work.
    My PSP’s firmware is 3.71 M33-3, and while I tried to install ver. 6.20 that came with the game, it says that “it does not read the disk.” So I couldn’t continue with the installation and play the game. I read somewhere online that the CFW might be affecting this.
    I know very little about CFWs and OFWs, and I wasn’t the one who installed the CFW in my PSP… but might you have any clue how to fix this/why this is happening?

    Or wait, should I just upgrade the cfw, or something…?
    Thank you very much if you answer my question lol.
