+====== firmware ======
+The source code is available {{ :grill_bomb:grill-bomb_firmware.tar.bz2 |here}} (including binaries).
+Note: it is not fool proof, and if you think about how it works, there are plenty of ways to cheat.
+For example, you win as soon as the 4 right cables are cut within the time, but cutting a wrong cable only speeds up the countdown.
+Thus, if you cut all cables at once, you immediately win :).
+Luckily the player was put under pressure from the start on, which distracted him from hacking the device (and he wanted to play the game as intended).
