@lightorion - Hi.. so since the time that I asked about this and now - I've gotten custom XMB themes working. To answer your question - wherever it is that you are looking for custom themes, just make sure you download the
CTF ones for the 3000... do
NOT use a a theme that writes to the flash - it will brick your PSP.
Another thing to note - do not just use the CTF theme you downloaded as it is... you need to convert it using the
CTF Converter. Just follow this tutorial -
CXMB for GEN-A 5.03!!!
and when working through the steps involving the CXMB plugin - use the
LITE version.
Another thing to note is, as I suggested, do follow the instruction from the link that I posted, but make sure you download the CXMB plugin from the link ultimakillz posted earlier in this thread -
CXMB for 5.00 M33 Released, PSP Hacks - PSP Slim Hacks
As long as you follow the instructions properly and make sure you only use CTF themes which you have converted with the CTF Converter prior to use, you should be up and running with a custom XMB theme in no time.
Hope that helps... gud luck!
