Hey Thomas, thanks for the insight! I never would have guessed that you drag that button into those fields! Gotta read the guide! Anyhoo, I checked to see if there were any P96 screenmodes in ScreenMode prefs again and there were some!
Instead of adding or edititing screenmodes you can use these Picasso96setting File.... extract it to DEVS:
The only thing to do ist to attach your Board.....in p96Mode
it contains any known VESA Standard Resolution and work perfekt with this Board
have fun.... nice card
