Homebrew developer JumpR dropped by QJ.NET PSP Development Forum and released a patch for version 1.8 of PSP Content Manager. The said program was originally coded by UFox. The patch should make the program compatible with the newest custom firmares 3.52 M33, 3.60 M33 as well as 3.71 M33.

PSP Content Manager allows users to manage and preview the different content of their Sony handheld on the PC. The patch itself contains three .REG files for each custom firmware. All you have to do is run it, select "Yes" and then you're done. You can remove the patch once you've already applied it.

JumpR also added that for this patch to work, you will have to run PSP Content Manager v1.8 first before applying it to the program. Once applied, it will slightly modify PSP Content Manager's settings in the registry.
