Rockman 4: Burst Chaser X Air Sliding is an insanely fast-paced romhack of Rockman 4. The general movement mechanic is, as the name implies, an air slide. Burst Chaser was another romhack that sped up Rockman’s movement significantly. Combining the two yields this lightning speed romhack. The music is also noteworthy, with Daytona USA standing out as a personal favorite. Watch my PB here.
