Submission instructions
Author's comments and explanations:
Konami's little Contra game beaten in 11:06 with FIRE! ;) 272 frames (4 seconds!) faster than my cancelled submission.

  • VBA-rerecording-14 used (works fine in latest version)
  • Used "Allow Left+Right / Up+Down" option.
  • No password and warp used.
  • Abused programming error with L+R / U+D option.
  • No hit taken.
  • Aim for fastest time.

This is Konami's little platform shooter game released in 1991 for Gameboy, it's just the same as Contra except for the title. There's 5 stages to go through and 3 weapon power-ups; I chose Fire Shot because it's the strongest weapon.

I decided to go over this game again, I knew it was improvable because I didn't get around to look at enemies' health in memory. Now I did this time ;) And also I ensure that it's fastest possible.

This new improvement is 272 frames (4 seconds!) faster than my cancelled submission. The area where I improved was less jumping and viewing enemies' health. The jumping cost 1 frame behind. Viewing enemies' health helped me to find when to begin shooting and make sure shots are landing each time.

Thanks to hero of the day for his comment on L+R / U+D glitch, and thanks to Nitsuja for his modified VBA.

Here's the table again; the timing is done for each stage when the screen turns white when a stage is completed and the end of movie.

Stage Old New Change
1 8638 8630 8
2 6955 6895 60
3 8655 8504 151
4 4335 4329 6
5 11623 11576 47

Enjoy the movie.


Nach: There is a place or two in the movie which looks sub optimal, but on testing myself I see it isn't. Accepted.
