Poison’s CXMB is now 5.00 M33 friendly. So all those [5.00 CTF created] themes you’re browsing here can now be enabled with ease.

Take note: themes created for firmware 5.00 will only work on 5.00. Custom themes for older firmwares are not compatible.

Update: CXMB 3.2.1 is here…

• Fix bug (freeze while applying theme)
• Fix bug (restore to original official XMB when returns from game)

Yes yes y’all… Just what you were waiting for — Poison’s CXMB version 3.2 with official support for custom firmware 4.01 M33. Customize it, theme it, skin it — make it yours.

CXMB v3.2 changes:

• Add 4.01 compatibility.
• Select the random.ctf, then cxmb will randomly apply your themes in /PSP/THEME/
• Compile universal binary, cxmb.prx should work on 3.71/3.80/3.90/4.01
• Fix some wrong io operation (I wrote some sceIoClose where there should be sceIoDclose)
• Clean up sources
