Glad to hear you managed to get the emulators working with your PSP Slim.
I have a PSP Phat w/3.40-OE firmware, with 1.50 compatibility mode and everything works great. Last week I picked up a PSP Slim and upgraded it to 3.71 M33-2 but I can't get a single emulator to work with it at all! :(
Can you tell me what settings you're using in firmware? Mine are as follows (maybe I am doing something wrong?)
PSP-2000 settings under the M33 Recovery Menu/Configuration (3.71 M33-2):
Skip Sony logo - Disabled
Hide corrupt icons - Enabled
Game folder homebrew - 1.50 Kernel
Autorun program - Disabled
UMD mode - Sony NP9660 -NO UMD-
Fake region - Disabled
Free UMD region - Disabled
Hard reset - Disabled
XMB Usb device - Memory stick
Charge battery when USB cable plugged - Enabled
Is anything sticking out here as misconfigured to get the emulators to work? Thanks everyone.
