MrWint's Pokémon Crystal glitchless TAS completes the Johto League including 8 badges and the Elite Four, then obtains the 8 Kanto badges before defeating Blue and Red for the final credits roll. This is done without any use of the typical memory corrupting glitches seen in Pokémon Gen 1 and 2 TASes.
The TAS instead uses luck manipulation to avoid encounters and spinning trainers, breeze through battles, and obtain Raikou as early as possible with optimal stats. Despite the run's length and complexity, console verification of the TAS was possible due to MrWint's own work emulating Crystal's Real Time Clock.
