In your system, does the scandoubler work with AGA screenmodes?
Forgive my ignorance but what constitutes an AGA screenmode? 32-64-128-256 color modes?
The Scandoubler doubles the 15k native modes so I don't expect it to do anything to the DblNTSC modes.
256 color screenmodes (NTSC Hi-res or NTSC Lo-res)?? Those are fine and look great. Interlaced modes work but are still interlaced (no Flicker Fixer in the CV64/3d+SD). Tried 32 and 256 color modes, they look great.
