This was my first attempt at creating a TAS for Ratatouille GBA. 6/17 levels completed. It was going well until I found about a second of timesave in Kitchen 1 (jumping up the shelves is faster than climbing the wire). I tried to implement this timesave, but it messed up the rest of the level, and I couldn't sync it back properly, so here is the TAS before I tried to fix it.
After this, I decided to redo all my work. I ended up saving time in the first level anyway. I could probably copy+paste inputs of later levels from this TAS to my current WIP, but I guess more timesave is possible.
This TAS stops right before the first actual cooking minigame. You need a certain qualifying score for each, but the game doesn't show you what this score is or what score you have. For now, this is my roadblock.
