UPDATE Custom Firmware 3.51 M33-4, M33-5 now available

July 18, 2007

QJ.NET PSP Development Forum mainstay blackbird 0001 has just informed us that Team M33 has come up with a new update for its custom firmware, bringing it up to 3.51 M33-4. Take note that this is different from the recent CFW addon provided by coder Test30.

Anyway, what we have here is a cumulative update, meaning previous improvements such as the WLAN fix and the no UMD function have been included again alongside new additions. Also, take note that this release is now complete with plugin options for 1.5 kernel homebrew. Anyway, here’s the changelog:

Bugfix for the released yesterday no-umd. This should fix the exit to the XMB with error 80020001 that happened to some people, or reduce its appearance.
Added plugins options for homebrew that use 1.50 kernel. The file to be used for it, is ms0:/seplugins/game150.txt.
There is other bugfix, but we don’t know if it will make much difference in compatibility.
In order to make compatibility tests, please remember that your ISO shouldn’t be more than 54 chars.

If this is going to be your first time to use Team M33’s custom firmware, please refer to the Readme file first before installing the program on your PlayStation Portable unit. It is also helpful to read the posts from our PSP Development Forum for an extensive discussion about this.

*UPDATE* (Original article posted Jul 18, 2007 at 11:15AM)

McDanny just emailed us of a quick update for M33-4 custom firmware by Team M33. In a matter of hours, the previous version has now been bumped up to M33-5 with a tiny bug fix. Tiny as it might be, its effects are substantially big. To quote his email (it’s also what’s written on the Readme file, by the way):

Greetings!

This update (yet another) fixes two important bugs in the no-UMD mode. The bugs affected SOCOM 2, Virtual Tennis 3 and probably many more games.
