After fiddling around with the MSU-1 myself I've decided to make a video of the famous (or not so famous) Video of King of Famicom
I still lack knowledge of actually applying MSU-1 to a real game, mainly finding the correct hijack slots. If anyone could help me with that or lead me to proper guides we could extend our MSU-1 Game Database even further!
Anyway, download and watch with bsnes or SD2SNES:
