i tried to use PSPoste Beta6.2 FW3xx on a PSP Slim and a PSPFat with CFW 3.90M33-2. If i start PSPoste (installed in ms0:/PSP/GAME/ or ../GAME380, the program loaded from MS, LED flashing and after 2-3 seconds it returns to XMB. Do you know any workaround or trick for me? In the ini File i have change the parameter for keyboard type 0. If i set the parameter to 15 8standard inn ini), the PSP crashed and go "off". (Slim & Fat)
(The same with Beta 6.1)
-- Edit --
Unfortunately I can't use Kernel 1.5 Version of PSPoste , my wlan works with WPA only.
