I cannot play games in my memory stick

Download the free program DosBox for PSP (see Resources). Save it to your PSP's memory stick under the "GAMES" directory. To do this, insert the memory stick in your PC's memory stick slot, or connect your PSP to your PC via the mini-USB cable provided by the manufacturer. Using Windows Explorer, open the memory stick or PSP and then navigate to the "GAMES" directory.

Install the PC games you want to play on your PSP's memory stick. When the PC game install wizard asks where you want to install the game, direct it to the "GAMES" directory on your memory stick. It should then create a new folder within "GAMES," where all of the PC game's files will be located.

Insert your memory stick into the PSP or disconnect the PSP from your PC. Start the PSP, and go to "MEMORY STICK" on the main menu. Scroll down until you find DosBox listed and start the program.

Type "cd/games" using the PSP's virtual keyboard option at the DOS prompt. (Hit the circle button to bring up the virtual keyboard.) Then type "cd/" followed by the name of the game directory for the game you want to play. Finally, type the name of the executable file (".exe") listed in that directory. Your PC game should start.

Troubleshoot your individual PC game by experimenting with the various game controls. Since the PSP obviously has fewer inputs than a PC's mouse and keyboard, you may have to use trial and error to discover how to play your game successfully on the PSP.
