No.23397 hap Developer 1 day ago	I removed suratk hack in this commit: https://github.com/mamedev/mame/commit/6b335b5475a654d5545c87c6b3e2520a9fab1b5d Combined col+rowscroll is emulated, but it doesn't look completely right in this game. The corners don't scroll. It's not an offset issue, eg. if you move the scroll effect or the tilemap itself, the left side of the effect won't scroll.
