Pyrofer is working on a great project using old Nokia LCD screens and PICs -
You can see ive managed to draw a basic map on the screen. The size of this map is limited by the ram, as the objects within have to change it cant be a rom map. There isnt enough RAM. Ive had to be very clever with ram byte handing to squeeze a large map into ram. Having static map layouts in rom isnt quite as bad.
Anyway, im about to add movement to the player and put some basic game logic in. Then its onto maps larger than the screen that scroll. This is still the original hardware from the temp probe, no changes other than removing the temp sensor and using the single input for player control.
