Issues with the memory stick... I can't play any games

Some things to try:

1. Update to 1.5.4, or better yet the latest git build which will soon be 1.6.0. It's better, faster, and has less bugs.

2. Check if other games are able to save. Also try copying the ppsspp folder onto your desktop and playing it there.

3. Double check your controller settings. The situation you described can be caused by accidentally mapping the same button to O as to X.

4. If you can, try it on another device (like your phone.) If it works there, at least it gives us an idea what might be wrong.

5. Make sure you have a clean rip of your disc. If you downloaded it somewhere, these versions are sometimes hacked for various reasons - sometimes to take advantage of bugs in older PSP firmware versions to enable piracy. We emulate PSP 6.6.0, so hacks like those often cause problems.
