PSP homebrew developer dsi has released a new version of his memory card game for the PSP, which he now calls PSP Memory Game v1.0. As the name readily states, it is a memorization game where you're tasked with matching cards together in the fewest number of turns.

Here are the release notes for this version of PSP Memory Game:

* now works on custom firmware (tested on 3.52 M33-4)
* new card images added
* minor bug fixes

The game lacks an actual readme, so here's a quick tip if you want to install the game: unzip the files to /PSP/GAME or /PSP/GAME150 depending on what firmware you're using, and you should be good to go. Enjoy!
