Some plugins were forgotten : mpegplayer, test_fps, test_scanrate
Some plugins use button_status() and can't use BUTTON_REL or BUTTON_REPEAT flags
rockblox1d : use single press BUTTON_HOME
doom : use single press BUTTON_HOME and BUTTON_POWER to open doors
I may have forgotten some plugins, I didn't test them one by one
