Yep, I know the game is interlaced and therefore not playable in 320x240 cause the screen would flicker like hell, but in 640x480 there are no flickering. The lines in the movements (sometimes, not always when moving) could be fixed with certain settings. the reason why they appear is because I use overdone CPU speed which forces him to walk a bit faster thus adding more frames and it's those new frames that are between his standard animation frames. But I wanted him to move slightly faster so I recorded it this way... if I wanted to, I could have recorded it without any horizontal lines (but he would have walked slower).
Winuae has no sync problems. It's all perfect for me. People just need to know how to set it up right for various situations and games.
