From the maker of the SCEP plugin, comes the Custom XMB plugin.
Basically this plugin, once enabled in the vsh.txt, will allow the use of custom RCOs from the memory stick instead of ones flashed to flash0
Guide Can be found HERE
Here is a plugin for CFW, It cant be easier to customize your XMB with this plugin in your system, It makes no change to your system files in Flash0, It just redirect the resource file path to ms0: by Hooking some funtions and doing some memory patch.
so, you know, It's always safe, you never have to take the risk of bricking your PSP in customizing XMB.
It is a part of SCEP project ,so a XMB theme controller would be brought into SCX...this module would be the core of that.
Download: CXMB 1.0 contains Calabi Spheres XMB Icons theme
How to Install:
Active it as the first plugin in vsh.txt.(or you can just flash it into flash0:/kn and add /kd/cxmb.prx after /kd/vshctrl.prx in flash0:/kn/pspbtcnf.txt)
How to Use:
Create a Folder ms0:/TM/ and put your resource files there like this
ms0:/TM/vsh/resource/ contains 1-all or none of these files
ms0:/TM/font/ contains at least the first 6 or none of these 19 files
and it works...
if you just use it as a OE plugin, you will get a BSOD when you start your PSP without your memory stick inserted. if you got BSOD.. you can shut down PSP and insert your memoryStick then reboot, or just press O to fix your registry. Anyway, if you flash it into flash0, there is no this kind of problem.
This should certainly help with the bricks/fear of bricking. :)
