The original aim was to take the original Apple 2 version of Taipan! and port it to run on an Arduino Duemilanove. Yes, I could have used a Mega or a Raspberry Pi or any number of other things but to get it working on a normal Arduino was the challenge (and it flaming was).
Turned out to not be possible. In the end I had to use two! One runs the game and the other runs the display using the Arduino TV-Out library. Due to memory constraints all the strings are stored on an external EEPROM chip read via I2C. The comms between the two Arduinos is done over serial using customer commands. The keypad is custom made and functions to allow entering letters and numbers. I am using a resistor voltage divider hooked to the keys so the keypad only uses one analogue input. Output from the TV-Out library is fed to a small LCD screen and also to a RCA socket so it can be displayed on an external video monitor. The library also allows sounds so the original game sounds were manually recreated.
