In Cheetahmen II the player again assumes the role of one of the three Cheetahmen (Aries, Apollo and Hercules); after defeating a boss at the end of the second level, they switch to the next Cheetahman for the following two levels, as in the Action 52 version. Due to a bug, it is impossible to get to the levels in which one plays Cheetahman Aries without altering the ROM image or experiencing a glitch that very rarely starts the game on these two levels. Though PacoChan released fix patch in order to able to play other 2 levels. You have to download the patch from here to play this movie.

Game Objectives

  • Bizhawk v1.4.0
  • Applied IPS patch
  • Aims for fastest time
  • Abuses programming errors
  • Takes damage to save time


Stop Walking: Enemy spawns are determined by frames or your character x position. So you should stop walking to manipulate enemy spawn. This is used in Level 4~6.

Infinite Jump: Physical attack can be cancelled with jump then you can do attack, cancel repeatedly. Apollo can't use this glitch.


114 frames faster than my previous run (you need nico account). I switched FCEUX to Bizhawk but there were no extra/reduced frames as far as I looked.

Improvements in Stage by stage

Level 1

Reduced lag from killing enemies in frames: 400~420. (1 frame saved)

Level 2

Better Dr. Morbis fight. (1 frame saved)

Level 3

Reduced lags with changing jump frame. jumped at 4454. (4 frames saved, 6 frames in total)

Level 4

Better Ape-Man fight. (2 frames saved, 8 frames in total)

Level 5

Using walking trick in some places. This allowed me not to kill or jump over enemies later. (68 frames saved, 76 frames in total)

Level 6

Walk tricks could reduce waiting frames and jump to cancel attack in Dr. Morbis fight. (38 frames saved, 114 frames in total)

Mothrayas: Judging.

FractalFusion: Added Nicovideo module.

Mothrayas: As stated in the previous submission's comments, the hack that allows completing the full game can be used to obsolete it. Therefore, accepting this run to obsolete the previous publication.
