Nice videos!

The two boss fights that really stick out in my mind that I had so much trouble with back in the day were the final boss of Karnov (NES) and De Rol Le from Phantasy Star Online (Dreamcast). De Rol Le on the GameCube version of the title was 'softened up' since it was so damn hard to kill it. And when you're in a mission that takes you back to that boss, the GC version makes that dopey scientist that you have to protect on the Dreamcast version fall on the ground and fake like he's dead so you don't have to keep dodging and moving to keep him alive.
