Advance Guardian Heroes GBA 2 player 60fps

Best viewed in 60 fps. I&player 1 and Mark is player 2. Note that this game has quite a bit of slowdown. At the last part of the final boss, the attack was originally thrown back at the boss 6 times, partly because I didn&know at first that both players need to press the R button at the right time. In this video, I cut it down to 2 times so the same thing wouldn&keep repeating.
