If you can post real disassembly, I can help you with that, I understand
Videl registers quite well. I'm too stupid to get the idea from this trace
outputs :) I'm personally very interested, what / why they do here, they
are/were beginners in Falcon coding, so I'm really surprised they didn't use
Evil's demosequencer or something similar for Videl init. Maybe they found
some neat trick!
