This submission is for the Japanese NES game Yie Ar Kung-Fu, one of the earliest ever fighting games, and is meant to obsolete the current publication: #2138: Selene's NES Yie Ar Kung-Fu in 01:49.12 by optimizing the fights and skipping the bonus stage.

The previous publication shared the relevant info about the game mechanics, with the most important aspect being the 65 i-frames in between hits. By digging in and reworking the fights, I was able to save 31 frames (comparison based on frame of last hit)

Stage 1 - 2 frames saved

Stage 2 - 5 frames saved

Stage 3 - 18 frames saved

Stage 4 - No frames available

Stage 5 - 8 frames saved/earlier input ending

With a frame perfect jump to start the bonus stage you can end it ASAP.

Besides the bonus stage, the bulk of the time save was in the Chen fight, as it is now "perfect" (each hit is 65 frames after the last.)

Lang (Stage 4) was already a perfect 65 frames per hit. Like Selene mentioned,there are some occasions throughout the TAS where it makes more sense to delay a couple frames to open up a faster overall pattern; the "first available" hit frame isn't always the best choice to take down the line due to the knockback and movement patterns which can create situations where you can't get optimal hits.

There is also a pseudo-global timer that changes the AI patterns a little bit. Even though you can hit on the same frame from multiple strikes/distance/etc. it actually matters what attack you throw to get the proper hit on the proper frame.

feos: Claiming for judging.

feos: Good job, accepting over [2159] NES Yie Ar Kung-Fu by Selene in 01:49.12.
