Hello pal,
I have a Tetris clone called Start'N'Tris. I think it's a Spanish game or something.
It's the best Tetris clone i've played on Amiga, but i'm not sure if it's what you're looking for. It's not exactly the same as Atari Tetris. It's a different game with it's own personality. But the scroll is very smooth . . . ok, it's on the Amiga, so it isn't anything new :-)
I coudn't find any references for it on the Internet, so i'll try to grab some screens to post here later.
