Whew. Now that i have the intro over with i can get to the fun part of this TAS. The tennis! Believe it or not but the intro actually had some frame saving techniques (i will go over in submission text when i'm done with movie). I basically had a frame war with myself (forever alone). For the tennis i think i will do doubles because i think it is slightly faster. I'm using vba-rr (18.104.22.1680.). If you have problems with the movie let me know. Also if you have any questions feel free to ask. The "(6)" in the movie refers to my backup version number. If you find another frame improvement please let me know but I don't think you can find one due to text box skipping and other strats. Good luck...
ROM name: 2272 - Mario Tennis - Power Tour (UA) (M5).gba
EDIT: I understand some of you may not have the ROM. I will upload an encode.
EDIT 3: Well I just realized you can run. I feel embarrassed know lol cause now it looks like the TAS is probably unoptimized. I'll fix this.
