This movie is different from the other Rygar movie in that it plays all levels and doesn't use any glitch to warp from a boss battle to another.
Aside from that limitation, this movie makes full use of all the bugs and glitches in the game which can be used to speed up the run. If you are wondering what really is going on in this movie, see the Rygar Tricks page for some info about the tricks used.
This is a 4 minutes and 43.38 seconds improvement to the previous movie.
Note: If you are watching the FCM, don't forget to enable PAL emulation in FCEU! It's under the Config menu.
