Thank you, dekutony, for preserving this run. TAS preservation has been a real problem with this game. iMathII's TAS is more polished than anything we've seen before, and I'm glad a submission is forthcoming, as soon as the verification is sorted out...
So
here's a verification file that completes the 150cc GBA cups twice to unlock the SNES cups, then the 150cc SNES cups twice to be able to skip their awards ceremony cutscenes. Two of the completions are iMathII's inputs, and the others are my sloppy 100-coin playthroughs to satisfy that requirement.
Here's iMathII's TAS, synced to the SRAM created by the verification movie. 2 frames were lost during sync, which might be because of my save data (it was 1 frame during each of the two cups with C ranks), but I'm not sure as I didn't test it. I also trimmed a blank frame off the end, and reset 135fr earlier since there's no need to save the game there (everything is already unlocked). Similar to the last race in each cup of
MK64, I showed the Special Cup times and rank for just a few frames. A resync that keeps those extra 135 frames is available
here.
Both versions of the iMathII .bk2 include iMathII's subtitles, condensed to be readable while watching the run, especially for slower/ESL readers. I wasn't able to fit the many extra notes from the credits sequence, but they can be included in the submission text. iMathII, thanks for doing this run, and for your work on MKDS too! Glad to have you in the TAS community!
As a bonus, here's
half of the TAS starting from power-on/a clean save and only doing the 150cc GBA cups, with cutscenes not yet skippable.
