Answer 1

I had the same problem. All you have to do is turn on your PSP while holding down the R button. Then go into Configuration -> Then make sure that Game folder homebrew is set to 1.50 kernel. (You can get it from here if it's not installed yet: http://www.pspiso.com/showthread.php?t=8... You have to sign up, but it's free.

I use 4.01 m33-2 and have the Universal remote control program.

Here's a link to the program you will need WinRAR to open the folder.
