PSP CFW 3.52 M33-4 – Custom Firmware

This is the third update to Team M33′’s custom firmware 3.52 M33. This update is accumulative meaning it has all the features any other update for 3.52 M33 has. The changes in this firmware are:

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.

AS we didnt 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 incompatible with those of 3.40+. We”ll research if a solution for this is possible.

Added a setting in recovery to change the usb device to which XMB will connect.

Added “vshmenu”, which is a menu that will appear when HOME is pressed in the XMB. It will interfere with existing XMB plugins that use HOME, so it can be disabled in recovery.
