Really works here (A600-ACA630-A604+IndyECS). Slow, but nice to see workbench in 256cols
First I didnt get pointer, but setting SoftSprite=Yes tooltype fixed this. And you need the latest (v1.10) indy firmware to get this working. I havent tried any P96 apps, but ShapeShifter - on IndyP96 screen- , but end with an error of lack of graphics mem. So it probably runs just a Workbench screen..
Anyway, Symplex is great achieving this, and especialy the beta IndyECS Shapeshifter Videodriver driver, which is much more useful, many thanks for all this.
