Author's comments and explanations:
The second title in the Valis video game series was released in 1992.
This Megadrive/Genesis version is completely different than Valis II on other systems though.

Movie features:

Normally you shoot at a 16 frame interval. When you crouch it takes only 6 frames to shoot and then walking and shooting takes 8 frames.

Shooting up
If you are walking you can cancel walking animation by crouching to make shooting a little faster.

Deals damage to all enemies on screen. Used to clear the spores that flowers sprout.

Celebration jumping (after beating a boss)
Jumping just before celebration so you have half done the first jump.

Weapons and suits
You get these for beating certain bosses.
There are stats (defense, attack, speed) on the select screen but they are not accurate.

Memory address for bosses: 00FF00D02A

stage 2
bosses have passive and aggressive patterns depending on frame of entering. I Manipulate them to be aggressive.


0:43 - Change weapon to wide beam.
1:00 - Can't crouch on top of a wall.
2:30 - Star gives invisibility for 15 seconds.
2:57 - It's barely possible to hit 5 times in a cycle.
3:26 - You can manipulate the dragon with your movement and shooting. Well, true for most bosses.
3:35 - Change weapon to triple shot and suit to speed suit.
4:11 - Only the lower part is vulnerable.
5:14 - level up. Weapons become more potent. This is fixed to happen here, so not dependant on points.
5:42 - Level up.
7:32 - Change weapon to normal shot. It deals most damage.
7:49 - Change weapon to triple shot.

Fog: Judging.

Fog: Normally, this would be a rather simple case of accepting for Vault as it looks somewhat optimized. However, with the existence of a WIP file from another author, a comparison needs to be done between the two to see which is the faster movie. An issue with comparing between these two movies is that they're both on different versions of the game (maTO using US version, with mtbRc using the JP version). At different points between the two movie files, the file which is ahead changes. I've chosen to split it based on boss fight finish up to the last completed portion of the WIP from mtbRc.

Boss # mtbRc maTO Difference
1 1805 1693 -112
2 3873 3807 -66
3 5744 5610 -134
4 6725 6632 -93
5 8057 8281 +224
6 10708 11181 +473
7 12000 12665 +665
8 14642 15224 +582
9 16813 17457 +644
10 18211 18829 +618
11 19850 20496 +646
End 20442 21082 +640

I've also included a video comparison to show the differences in real time.

Language differences aside, there is clearly a big difference (nearly 11 seconds) between the two movie files. With this in mind, I can't in good conscience accept the current submission as it stands.

Rejecting for not beating a known record.
