This directory is for temporary files during testing.

Doing a "make fwtest" does the following:
  - copies firmware/afminitools.crt here as testaf.crt

  - injects the following (if available) to testaf.crt:
    - inject_disk.d64
    - inject_prg.prg
    - inject_ar.crt     (Action Replay cartridge, to AR location)
    - inject_rs1.crt    (EasyFlash cartridge, to ROM SLOT 1)

  - if no disk_in_drive.d64 exists, copies empty.d64 to it

  - filters the firmware labels of non-label entries

  - starts x64sc_sdl with testaf.crt and disk_in_drive.d64 attached,
    adding the filtered labels to the monitor
