Here's another soft-lock manipulated from feos' movie:
1. The game can be soft locked, but most of the time it will recover after 2000~5000~13000 lag frames.
2. As Scumtron wrote, since the game uses the 0x6D which looks unmanipulatable, the game will come back to a state where you can press start and loads 0x6D, which is always the place where you did the double KO (only boss1, boss2 tested).
3. You can't warp to another level, because the KO glitch doesn't increases 0x6D only after revisiting the level, so the game takes you the next cutscene after the boss level started.
Only ideas I have as Scumtron suggested is getting more score to have enough time to end a screen and hoping for something spicy.
edit: if you somehow able to go to the boss screen (double ko boss2, freeze timer value, go to boss2 again), the timer will countdown again from 150 and proceeds to next level. Obviously this is impossible and worthless.
Any thoughts of working on the sequel as well?
moozooh: Indeed, the published run was done with little more than memory watch and some (mostly) naive assumptions based on that, but when you consider that the game is still primarily around eleven minutes of scrolling the screen at a constant rate and waiting for the next part to load, then it's not surprising how little room for improvement there is.
Stack corruption: interesting, I've tried to recreate the situation on other levels without success (picking up a "bonus 1000 points" powerup and position differently to update score graphically while reaching the interrupt zone since killing the bird doesn't affects this).
It looks like a lag frame, however if you append 1 frame (to reach the ladder), it will strike again at 13314
edit: probably useless fact but it's 16*60 difference between 13314 and 12354
Possible mprovements and their effect to 5-2 final knife bitch:
* feos' RTA trick at 5-1 start saves 5 frames for 1 HP. This way the knife bitch fires 13 frames earlier, which is really bad.
Frame 26788
* the same 5-1 boost and avoiding the ballerinas (jumping roundhouse kickers) at 5-2 for 13 frames the knife bitch still throws bad knife
Frame 26825
* avoiding only the ballerinas let's us jump over the knife bitch, but this way we need to manipulate bird 6 to be slower so we can boost over slot7 bird, this way we finish stage 5 with 1 health (3dmg = avoiding 2dmg ballerinas and 1dmg bat at 5-3)
Frame 26833
So currently I'm sticking to the last one.
Other improvements pointed out by Scumtron, 5-3 final walljumps were not perfect, so 2 frames can be saved at each place (3 times), saving 6 frames. And subtimer will be need to manipulate to get our sweet 3 frames back. Stay tuned :)
edit: and another one spotted by Scumtron is better jumping at 5-3 1st screen between tysons to save 1 frame.
jhztfs has updated the input. It can be seen here: User movie #32183071323127486
I always hoped that legendary farewell letter about "I won't be a part of this cancerous misery" was just temporary insanity.
EDIT: I tried the input MESHUGGAH mentioned and it gave me a 7 frame slower fadeout of 599 instead of 592 in the submission. I cannot find any sequence of input in Bizhawk that beats frame 592.
