There's a new version of poisonhzkj's Custom XMB plugin available. For the uninitiated, CXMB is a custom firmware plugin that allows for easier customization of the Sony PlayStation Portable's XMB.

Anyway, this new release bumps up CXMB to version 2.5. It has 3.71M33 support, albeit to a limited extent. According to tests done by QJ.NET Forums member madsoul, the only things you can change with CXMB v2.5 without causing your PSP to hang are the background and the wave.

QJ.NET Forums member NorthernFusion, meanwhile, reports that some backgrounds mess with sub icons. NorthernFusion also noted that testing was done using 3.60 custom RCOs. You can find out more by clicking on the Visit link below.
