Developer's note:

Update Squaro PSP
- Possibility to mark a red circle (with the O button) when you are sure it is empty.
- Adding an mp3 player (in beta).
Mp3 files must be on the memory stick in the folder "PSP / MUSIC /"
L + R displays the player anywhere in the game
Cross: Play / Pause
Triangle: Stop
Round: Next Track
Square: Previous Track

A bug apparently impossible to load more than 8 sounds, if you can load in more or other bugs, please send me your feedback on the player. The mp3 with accents or special characters in the filename will be ignored.

If you have a previous version and want to keep your gates validated, just keep the file "grid" that serves as backup, this folder "data" folder of the game
