Yet another 5200 prototype. This time #003 and with source code.

    Cartridge file has .bin extension
    GTIA consol register poked with $04 to both select controller #1 and enable POTs
    Fixed reading of the keypad using the continuation vector pointed from $020A. It is still not perfect, but it is enough to allow the player to commit suicide or return to the main menu.
    The suicide/return to menu controls match what is written in the training screen.

I have checked the phobos port for joystick dead zone to realize that I have almost the same.


Features to go

    Audio - Porting RMT player
    Fix PAL/NTSC woes - either detect PAL/NTSC by examining GTIA register if possible, or change compilation script to generate two cartridge images (one for PAL, other for NTSC). Correctly set PAL compatibility byte at $BFE7.
