got all but the two in 5-3. hilariously, my fix for that one affected slot 6 ysub which causes that very last goblin in 6-3 to hit Ryu right before he reaches the exit. before edit $47e = 0x52 after edit $47e = 0x57 and anything <= 0x56 would be fine.

Faster, but requires extra freezage around frame 12683 to set up the big leap at the end of 3-2, which screws up the clock for the act IV boss.

you make a good point; this one's a frame ahead

last worked on this March 2020.

#7238: J.Y & aiqiyou's NES Ninja Gaiden II: The Dark Sword of Chaos in 09:11.71 is a frame faster on 5-2b and 7-4; not sure if it it's possible to edit those gains into this without losing the frames later.

NESHawk synced

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:

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.

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.

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

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).
