It'd be nice for Ghost Squad arcade machine owners to have a hacked version that unlocks all the content locked behind a card reader (pretty much like with Ghost Squad Evolution on Lindbergh). This would help ops running this game on location so we don't have to deal with anything card reader related (including a card reader emulator).
Because this involves modding the game image itself, I don't know if this will be possible.
