Before the rise of the Nintendo Gameboy, Tiger LCD games were the king of handheld gaming. Inexpensive and appealing to a wide audience, you still often find them “in the wild” or lurking in your house, even today. When [Lee] found a “Wheel Of Fortune” model laying low in a box, having a look inside and turning the handheld into something it’s not.
Being based on a game show, this specific model has a feature most Tiger handheld’s don’t: a cartridge slot. Originally intended to supply additional categories and phrases, the slot is a wide open bus to the internal CPU. It didn’t take long for the some probing with the Bus Pirate to decode the data protocol.
So what does one do with a hacked game show game? Well you could just make it say goofy stuff, or you could make it into a TOTP password generator. Future plans are to take off the computer umbilical cord and bit bang the cart slot with an AVR. Once done anyone, trying to break in to [Lee’s] PC will never suspect the innocent old toy is the key to the kingdom.
