I've just managed to get my really, really old, unfinished project 'Monty Mole Remake' (see http://montymole.sourceforge.net/index.html ) compiled on my shiny new Pi.
I started this in Y2K and never really got around to finishing it. The code is embarrassingly old hap and very badly formed C++. But, it runs very smoothly and a nice speed, so might be worth completing in order to add to growing list of games for the Pi. Any votes for/against a Monty Mole Remake on the Pi? I'll get a tar together of the demo for anyone interested.
