PressMe is my first homebrew coded in C. I started programming in C on PSP a while ago. I created this homebrew to see what I already knew and make it a utility for noobs in particular. This utility can check that your keys are working properly. The homebrew has 12 buttons yet.

Many people on forums no longer come back to the XMB properly when they are full games and croyent while it is a problem which is not hardware. With this homebrew, you will know whether this is the case. If you run the homebrew and he tells you that a key is pressed, is that it is stuck, and it is therefore hardware. I put online the source code and of course free to developers of do what they want.
