I was going though some of my old demo's and came across this one, and I don't think that I would have uploaded it except I found that My super CPU had an odd effect on it. I have had this demo for years and never knew that there where supposse to be a scroll type text at the bottom. when this program is booted up in normal 1Mhz mode you never see it, however once I enabled the Super CPU I discover it. There's a file some where called gbTetris and I noticeed a lot of flickering when the file is run at 1Mhz but once it is taken to 20Mhz the program run a lot smoother.. adamw@mail.hvs.com
