Firstly, to avoid misunderstanding: This program is NOT for psp 3000. It is for psp1000/2000, but it allows the decryption of psp 3000 prx's for researching purposes.

Modules specifically of psp 3000 usually end with 03g. From the files, it seems that umdcache is handled differently in psp 3000, and that psp 3000 comes with a new wireless chip.

P.D: better looked now, it seems that wlanfirm_02g and wlanfirm_03g prx are equal. Same happens with umdcache_02g.prx and 03g. It seems that Sony enjoys making redundant data to make update eboots bigger
