Mednafen on Windows with TG16-Mini USB Controller. The strat here was to prevent the enemy from gaining either of the corner factories, and to set up a well defended artillery nest to pick them off in the middle while my Charlie moved down to take the base. There are likely still plenty of time saves available by not engaging in ancillary battles, and the Charlie should be able to take the base by turn 13, not 14, which would shave off another minute.
