I try to use block-bounce trick with toad, but fails. So I wait 7 frames before meet boss for making Birdo fall down quickly, and use the same way like the warpless run. Total saved 20 frames.

I'm amazing there are 4 frames be saved after rocket before climbing, maybe I meet the bad subpixel in my old run.
I loss 1 frames in boss fight, because of the frame rule, I have to avoid fire ball.

I cost near 20 frames to save the last 2 lag frames. Thanks to the better subpixel, I can use the perfect way to catch the crystal ball with full speed. But I still need 10 frames for touch Wart's frames rule line, if I don't cost time to save lags.
Thank to andrewg find this Wart glitch long time ago, and it still work in snes version. Because I didn't touch the Wart frames rule line, so It's the best chance to use this glitch. Save the last 182 frames after boss fight.

I press start just for keeping Wart in more left for this picture.
