This run is a improvement of 124 frames, due to better use of the Item Boost technique, lag reduction, a death in stage 1-3 and a shorter last boss battle. For all the tricks you can read the submission text of the
This stage is pretty much straight forward. I get a better position, when I'm climbing the first horizontal rope, which makes jumping up the second rope faster. When there are two many enemies on screen I delay the Item Boost to reduce lag.
Here comes most of the improvement from lag reduction.
In this stage a massive amount of frames are saved by using a death and skipping waiting for the elevator. However I'll lose a lot of the improvement in Stage 2-1, because I don't have the double sword powerup there. The sword powerup is lost when dying, that's why I'm not even getting it here.
The improvement here comes from being in mid-air while doing the thunder attack, which then let's me do a sword slash in mid-air, the next attack on ground can be done as soon as I'm on the ground without waiting until the attack animation is over. Also in boss stages there's some kind of weird frame rule.
I lose a lot of frames here, because I don't have aimbot shuriken for the mecha snake battle. The double sword powerup is needed to get them. However it's still ~20 frames faster, than doing it without the death in 1-3. Relative improvements come from lag reduction, of course.
One frames saved due to adding one Item Boost.
Lost some frames, because of the frame rule.
Here comes some improvement from better positioning and lag reduction, a lot of frames are saved in the boss fight. Doing the first attack in mid-air is faster than doing all four of them on ground, which then improves it by two frame rules
Frames are saved after climbing to the top of the stage due to lag reduction.
A lot of frame saved because of better positioning and lag reduction. I even needed to create some lag to prevent the moving box from being faster than the ninja himself, to be able to jump over it, without slowing down.
Saved some frames due to the frame rule.
Lot's of frames lost, because it's not possible to manipulate enemies. Their actions depend on wheter the address 0x0000 is negative or positive. I would lose more frames waiting for it to change.
Basically an auto-scroller, removed all lag frames in it. For comparison the old run had three lag frames in it. The auto-scroller will be a surprise for viewers. Most of the improvement come from shortening the boss battle.
