PSXP what did you do when it went to the screen with the numbers on the left? It's doing that to me right now and i have no idea what to do. Should i just wait until it's done or try to turn it off? If you or anyone else that it did this to could reply back with what you did i would greatly appreciate it. Thanks.

Alright i went ahead and pulled the battery and now everything is fine. I was just freaking out a little there since i didn't read anything about that.

So I'm downgraded and I have all the nessesary fixes. but I am having one very specific problem. the ROMs that I load are very slow. I am told that this is because the cpu is running at 222 mhz and I must turn it to 333 mhz. but I do not know how to do this. for your information, the emulator I'm running is
uo_Snes9x the version which was released august 18th. can someone please help me with this?

So far the snes emulators aren't really up to full speed yet. The only way to get them to play decent is with frameskip on something around 2 or 3 with the cpu set at 333mhz, but to answer your question i believe you hit left on the analog nub on the psp and then it will take you to the emulators set up screen. Somewhere around the bottom of the screen you should see something about cpu speed and be able to turn it up to 333mhz. You may want to stick to Nes games with nesterJ or i read that the sega genesis games play pretty much perfect with the MegaDrive emulator.

I have ran this downgrade twice but can the psp STILL BE BRICKED!? does that chance exist? I'm scared to ever do it again i took a big enough chance doing it twice. and i didnt use the "beta 1.00 version" of it. is the newer version better to use if i wanted to do it again? Feedback? i need one of my psp's to stay 1.5 forever thats why i have 2

thanks
