There are hidden keys inside the remote control.
(no plastic button to push it from outside)
Open the remote control of your Mustek V560 DVD Player, (no screws - use a knife or a flat screwdriver)
Let the batteries and the circuit plate in place,
just get rid of the top.
Keys are easily identified by two numbers,
ex: mute = 24-21
Find the unused key numbered 5-17
(one key under mute, then one to the left)
Power on your dvd player, press the 5-17 key using any other key's button.. et voilà !
SNAKE, TETRIS and MINES on your dvd player !
have fun !
