Help with 3 emus

hi, I was wondering if somebody could help me with some emulator trouble

Picodrive:
I've heard that this is able to go into sleep mode, but when I flip the switch, it just off my psp, is there something specific you have to do to get the psp to go to sleep while this is running, if not, is there an emulator that will

Snes9x:
It works fine, but same as above, is there a way to get it to go to sleep, or is there an snes emulator that can

cs2psp:
It just wont work, I set up the cache files then I zip the files in my cache and move them into the emulator folder, I've tried 2 games megaman power battles and megaman power fighters, i move the zips to the roms folder and give them the correct names but it gives me this error message

For power battles:
"Could not locate mcmu.03a"

For power fighters:
"Could not locate rcmj.03b"

does anybody know how to fix this

THANKS IN ADVANCE FOR ANY HELP

Unlucky about the problems..
Can you be specific about the psp firmware version...and psp type for that matter (phat or slim) maybe that you installed wrong type of homebrew slim instead of phat and vice versa.
SOMETIMES THIS WORKS,,,,,
Try backing up your ms pro duo to your computer,

Then format the ms pro duo in the system sub menu,

Move psp contents back onto ms pro duo...

Try Homebrew

If this doesn't work try "reinstalling"(1) the emulators...

(1) being redownload and put on mem stick.

I knew I was forgetting something

I have a phat with 3.90 m33-3

cps2psp:
Willing to bet you have the wrong roms.

Sleep mode using firmware greater than 3.52M33 has problems with home brew.
Plenty of evidence for this if you Google it.
There doesn't seem to be any one fix.
Could be another version of the emu or ipl...

Suggest you use save states, exit the emu and then sleep.
