Portal

Martin Poupe, managed to port the classic game Doom to the latest Casio model, Casio Prizm Fx-Cg10/20.

Due to calculator hardware limitations, the game runs a little slow on the calculator. However it's still a great job!

I let below a video of the game running on the emulator:

Controls:
arrows - movement
[alpha] - fire
[exe] - use (open the door,...)
[^] - iddqd + idkfa
[F1] ~ [F5] - weapon select
[Menu] - exit (the calculator will be in somehow wrong state, if menu is not working, try to turn it off and on)
