Tech

The following is cited from snapshot64.c found at the VICE project page:

    Snapshot 64 (LMS Technologies)

    FIXME: this implementation is purely based on guesswork

    - 4K ROM (2732)
      - mapped to 8000 and e000 (ultimax mode) ?
    - NE555, 7406, 7474
    - one button (freeze)

    io2 - df00 (r/w)
     0 - cart off
     1 - cart enabled

    after reset NO menu is shown. when pressing freeze the screen goes blank, then

    return - starts the "code inspector"
       l - load and execute ml program
       j - jump to address
       d - dump memory (hex)
       e - return to basic
    f1 - analyze and save backup
    f3 - clear memory
    f5 - format disk
    f7 - restart

SuperSnapshot v3 should be compatible to this - the info is somewhat lacking though. supersnapshot4.c:

    Super Snapshot v4

    - 32K ROM,4*8K Banks

    io1: (read/write)
        cart ram

    io2 (read)
     df01 - ram config
          - cart rom
    io2 (write)
     df00 -
     df01 -

Super Snapshot v5.x emulation is handled by supersnapshot.c and reads:

    Super Snapshot v5

    - 32K ROM,4*8K Banks
    - 32K RAM,4*8K Banks

    io1: (read)
        cart rom

    io1 (write)

    df00/df01:

    bit 4 - rom/ram bank bit1
    bit 3 - rom enable
    bit 2 - rom/ram bank bit0
    bit 1 - ram enable, EXROM
    bit 0 - release freeze, !GAME
