Symbian OpenTTD

A series of patches to OpenTTD and SDL that allowed the game to run on Symbian devices. The game was fully playable with the physical keyboard input controls, and later with touch input on S60v5. MIDI synthesis was implemented using TiMidity. Downloading GRF packages from the network was supported, but multiplayer didn’t work.
