Video: Super Mario Bros. speedrunner Kosmic seems to have shaved the record time for completing the 1985 Nintendo Entertainment System classic by three frames, based on a video and Tweet he posted yesterday evening.
I beat the Super Mario Bros. world record AGAIN! I beat the game in 4:57.194, an improvement of 3 frames (0.05)!https://t.co/kMTUtXCqWs

Kosmic said on Friday that he beat the Super Mario Bros. world record held by ace player Darbian by a single frame. He walked that claim back after detecting a "lag frame" earlier in the run.
