Problem: the bat boost in 2-2C can put Ryu a half-pixel more to the left—enough to reach the exit a frame sooner in this case. But that change would make the next tosser throw an unavoidable knife, negating that tiny improvement.

Solution:

  • use spin slash instead of windmill star to clear 2-2A (-1)
  • take better 2-2C bat boost. now the upcoming tosser cooperates because of the different timing. (-1)
  • kill one enemy with down+b due to lack of ninpo (+1)
  • act II ends a frame sooner (0-1-1+1=-1)

But none of that matters. The tosser-boost in 3-2 is acting as a gatekeeper, and it would take at least another 2 frames of improvement before 3-2 to get past him.

Not sure how much of this can be kept since it's hard to jump into a run like this without knowing the reasons for every decision.

  • 22230-23350: Wasn't sure if some subpixel management was going on here, but I tried something different and it worked.
  • 23412: First guy banished with 3 L-presses.
  • 23670: Climbed the right wall to go over backwards and give up a pixel (R @ 23719) to set up the next two dudes for optimal removal.
  • 24091: Bird spawning late had me worried, but a one frame delay before it gets right of Ryu and another during the boost jump kept things moving.
  • 24346: LR on the first frame of regaining control to trade a half-pixel for one more spawn prevention. Bird ends up being super cooperative too!

Also tossed in a blank frame before the slot 5 guy near the end is scrolled off to fix xsub for 5-2A, but more desyncs are right around the corner.

  • The RTA trick in 5-1 feos found a way to make TAS-worthy the other day only turned out to save 2 frames since it had to be traded for another damage-boost due to health limitations. It's also possible to grab the windmill star in 5-1 and trade 1 frame for 4 more health, but seemingly not without killing the slot 6 bird from the unused boost at the same time.

  • That 2 frame difference set up a new boost in 5-3E which saves another 3 frames. Reaching that point at least 2 frames sooner would also save save another frame, but oh well.

  • Those improvements finally fixed the two tossers in 6-2 that were each costing 1 frame to deal with.

Stage 5-6 from 39110 WIP pasted onto Meshuggah's stage 4 changes with a few tweaks to sync things up again.

  • 5-1: Attacks on frames 22761, 23014 delayed one frame to fix slots 5 & 6 subpix values so 2nd bird-boost works.
  • 6-1: Jumps/attack changed before axe-tosser to avoid axe
  • 6-2A: Check out that club that Ryu nearly runs into. Scary!
  • 6-2B: Jumps/attack changed so tossed axe gets killed and fixes xsub for booster enemy 2 screen ahead
  • 6-2D: Less windmill action for now, $BF causes ghoul to stand in the way
  • 6-2E: Tosser still not cooperating, so still losing 1 frame to get through here. Adjusting spawn iterator (interrupt@33781) in dead frames on platform jumps isn't quite enough to fix it either.
  • 6-3C: disc-guy killed one frame earlier so the bird cooperates. (xsub again)

I still haven't looked at the 4-2 changes closely. Not expecting to improve it, but I should probably at least know that for myself

A cowardly warp to Leaf after squaring off with Stom results in Tornel rewarding you with Telepathy and moving things forward as if you'd won.

FM2 file begins from a savestate

Taking damage on the same frame as killing a boss results in $75 being set to 4, where normally $75 is always 0. This can occasionally prevent speed values from being added to enemy projectile positions, illustrated here with the bullet-boost leaving 4-1A causing a desync (though other bullets in the level are affected too).

trace logs from frame 487 for both taking and not taking damage: http://pastebin.com/sqkrSDe7 http://pastebin.com/zFeBTbUq (I have not yet analyzed these)

edited trace logs corresponding to frames 2536-2537 in this movie, for $75=0 and $75=4: http://pastebin.com/DeW5DMMV http://pastebin.com/N1zYULW0
