e1will Posted September 27, 2010 Share Posted September 27, 2010 Cool. I've always wondered about that. How curious that it should be part and parcel of having to reposition a sprite. Maybe it's a timing thing (i.e. it's not "caught" before each screen update)? It's definitely timing related. STA HMOVE is the actual command that causes the black line to appear, and there are reams of info and discussion to be found about how it works and how to get it to do neat tricks. Ed Fries recently talked about it a little bit here, which is probably a decent introduction. --Will Quote Link to comment Share on other sites More sharing options...
