Time is about 17:25.56 under modern fps. About 17:24.22 under past fps.


  • Choost the best ending of 6 endings.
  • One player in a multiplayer game.
  • Takes damage to save time.
  • Luck manipulation.

I found that $A078 always means lag. But sometimes failed to catch out lag. So it isn't 100% right.

About improvement

  • Stage 1: 41 frames.
The player can't slide at the first frame that the player fall to the ground. And player will not move if you don't press L or R. But I found that too late. So I lost some time in stage 1. And I improve it this time. However, I can't believe that I can save 20 more frames against my secret ending run.
  • Stage 3: 190 frames.
Beat every boss faster.
Also, the door and movement after scroll-lock in this stage is different from others. Door has its HP this time. Not 1 beat by every 4 frames. And the system will force player's x position to be 64 after every scroll-lock. So we should beat door earliest and move to the right place earliest.

  • Stage 4: 70 frames.
Beat bosses faster.
  • Stage 5: 204 frames.
Beat bosses faster.
  • Stage 6: 7 frames.
  • Stage 8: 73 frames.
  • Stage 9: 180 frames.
    • View 1: 127 frames.
Better boss fight and better walking.

    • View 2: 53 frames.

  • Total: 765 frames.

Memory: Judging

Memory: This looks to me like a good improvement to the existing run.

Hard Corps was already a fun watch with the sliding technique and insane amounts of action, this is only cleaner. Audience reception was decent too.

Accepting to Moons as an improvement to [1755] Genesis Contra: Hard Corps (JPN) "best ending" by Soig in 17:36.97.
