Rockman Complete Works: Rockman 2 is a port of the Japanese version of Mega Man 2 to the PS1. Notable changes include fast weapon switching (though one still has to go to the pause menu to select Item 1-3), bug fixes (notably no horizontal zipping) and a Navi Mode, which includes an updated HUD, hints for beginners and a partially re-arranged soundtrack (by inputting an input code when selecting Navi Mode).
While this TAS by paosidufygth seems slower than his previous attempt, it is in fact faster by about 12 seconds. This is because the emulator used, PSXjin, assumes a framerate of 60 FPS while the site assumes the PSX framerate to be the proper 59.292 FPS.
