This is what I have so far for a WIP of level 1 of Battletoads for the NES with 2 players without warps. If anybody has any suggestions or ideas to make things faster, I would greatly appreciate it!
#60692970367434523 - Battletoads Gameboy First 6 Levels
This is an improvement over the published TAS which also includes the second level of the game, since there is content in the second level not present in the first level.
