Hacker Mathieulh has released the source of the M33 CFW, as well as for Despertar Del Cementerio, two essential tools back in the days of PSP hacking. This release celebrates the 10th anniversary of the tools. M33 meant “March 33rd”, or April 2nd.
The public face of M33 was famous PSP hacker Dark Alex, but other hackers contributed to the two tools, including Mathieulh and adrahil, the two other members of Team M33. As most of the developers behind such tools have moved on a long time ago, it made sense to finally release the source.
M33 was widely used as a custom firmware for PSPs, until it was later replaced on newer models by TN HEN and CFW Pro, both of which were based on reverse engineered versions of M33.
Despertar Del Cementario was a tool used to unbrick and downgrade PSPs, with the use of the “service mode” batteries. In those days, entering service mode on the original model PSP only took a special battery with serial code “0” (or was it -1?), which then allowed “easy” access for downgrade, unbrick, or to install custom firmwares.
The combination of DDC and M33 was nothing short of magical: one would insert their magic battery in the device, boot it, and be presented with a Sony-like menu to install a CFW. Everything looked and felt like an official Firmware install, except more magical.
To this day, I still have my DDC kit (the battery + the memory stick on which DDC is installed) to easily switch between firmware on my PSP.
In practice, this release will not be useful for most of you, but for PSP and ePSP (Vita) developers, it it a critical piece of PSP hacking history.
