Rockman 3: Speed Bound is a ROM hack of Mega Man 3 that combines the ROM hacks Rockman 3: Burst Chaser and Rockman 3: Claw. It takes the sped-up movement from Burst Chaser and sliding mechanics and weapon changing features from Claw and adds in original level designs and music to create a unique experience. Like the romhacks it borrows from, graphics and AI behavior has been changed as well.
Watch longbao zoom though the romhack as fast as possible, making liberal use of various weapons Mega Man can collect.
