Have a flag for linedoubling in the config file to make ot permanent. Maybe i have not found it, could be my fault.
This already exists : gfx_vresolution
Is the same as in WinUAE.
Probably needs adding to the host prefs for Whdload auto booting though
Sure, its in the .uae config, but as HoraceAndTheSpider said, its not in Whdload prefs.
Ah sorry, I misunderstood then...
@HoraceAndTheSpider re-opening this then...
Fixed in commit 2438bd1
