- fixed aspect ratio correction (overlay destroyed its state, keyboard shortcut didn't always work), as well as significantly sped it up on VGA and SuperVidel - smoother transitions between video modes - reduce the number of video mode changes - fixed a few extreme cases when triple buffering could lose an update - lighter ST RAM usage in the lite build - removed hardware accessing init/deinit routines
