PSP Longplay [026] Irregular Hunter X (JP)

This game is basically a remake of the SNES classic Mega Man X. Supposedly, the creator (or something) wanted to do a remake of all of the X games up to 6 (I think) but Maverick Hunter X flopped.
Some differences between the SNES and PSP versions I can think of are part locations (Dash is located in Flame Mammoth's stage. The game can be completed without it. I did it personally), acquiring the Hadoken (go through Armored Armadillo's stage without taking damage. Charged Rolling Shield FTW), Vile has to be defeated in the intro stage, and Sigma Fort stage layouts. Oh, and Zero's buster charged shot is different from the one X gets from the capsule (you get Zero's buster by defeating Vile without the buster upgrade in Fort 3).
