Battletoads is among the most notorious NES games for its difficulty, and its speedrun demands frame-perfect inputs through the Turbo Tunnel and Clinger Winger stages that eliminate even experienced runners.
Battletoads' speedrun is as famous for its failure rate as for its times. The Turbo Tunnel — Stage 3, the game's most notorious obstacle — requires memorisation and frame-perfect reaction to a series of walls at escalating speed. Even top runners fail it regularly in live runs. The Clinger Winger stage in the game's second half and the final boss add further near-frame-perfect requirements. Speedrunners use a warp in Stage 1 discovered in the early 2010s that bypasses three stages, and the Battletoads run is unusually routing-stable — there are relatively few glitches, meaning improvement comes from tighter execution of a set route. The game's reputation for difficulty means completed runs are relatively rare even in competition.
