Nintendo Revolution

INVADER1 is correct on the GUNS song which takes up most of the video.

When the castles appear, it's playing these songs in order:
Super Mario 64 Opening
Part of Super Mario 64 Ending Demo
The intro ditty from Super Mario 64 Metallic Mario
Super Mario 64 Koopa's Road
Custom ditty meant to resemble the Super Mario Bros Invinsibility Theme
A sped-up portion of Super Mario 64 Ending Demo
Back to the Super Mario 64 Koopa's Road
Instrumental version of the Super Mario Bros Level Complete Theme

All of the above is usually overlayed with techno-y instrumentation/drum beats and an occational ditty from other games that appear to be made by him (Psycol3er), but all of that was basically remixed Super Mario 64 music.

After that, there's some weird music that I wouldn't call music while the Nintendo ON unit is displayed at very high zoom. But if I have to say it sounds like something, it shares many notes in common with the Luigi's Mansion theme, though it lakes all definition.

Excuse me, I meant dabreegster was correct about the Guns song.

Over a year after I started this topic, I have found the song I was looking for, thanks to it being used in the recent Castle Crashers game.

It's called Helix - Archetype and is a totally free song from a Newgrounds user named Helix6. Listen and download it here:
