Like a lightning bolt out of the blue, Team M33 strikes unexpectedly with their fourth update to their very own Custom Firmware 3.52. It's not as major as the previous one, as it's mainly a bugfix that takes care of a few nagging issues the team must have missed after they rolled out their highly-anticipated third update. In any case, let's get to the changelog and see what's new!

Changes in M33-4 (mainly bugfix)

* Fixed the bug that caused CRC error when writing to flash usb in the XMB. Now writing is OK.
* Added the new speeds to vshmenu and core, because we forgot in recovery.

Also, a few notes from Team M33:

* As we didnn't want to release a new update without something new, we worked in making 3.10/3.11 to work with popsloader, and that's it, the new popsloader plugins supports them.
* Instruction for 3.10 and 3.11 are same as 3.30: you need pops.prx, popsman.prx and pafmini.prx with the correct names in popsloader directory. And remember that savedata of 3.10-3.30 are incompatiblewith those of 3.40+. We'll research if a solution for this is possible.

Not a very long list of changes, but very considerate of Team M33 to put out an update so that PSP homebrew enthusiasts would have a better time with their CFW. As usual, please, please, read the relevant readme files included in the zip archive before you do anything. Installing something that tinkers with your PSP's firmware without the required knowledge and information could result in a bricked handheld, and loss of portable gaming joy. It will not be pretty.
