I'm learning Blitz Basic 2 too. Most of the bb2 source code available out there won't compile in Amiblitz2.43, for example Leathered's FF wip code compiles but there's no characters displayed in game.

In BUI5 there's an example using the Display mode instead of Amiga mode or Blitz mode (well still blitz mode but with display library instead of slice)

  End



; NOTES

;   Both the fade routines take the same parameters, which are :

;   clist       :=    the copperlist where the fade is to take place.

;   source      :=    the palette number to fade.

;   destination :=    a spare palette to hold the faded colours.

;   speed       :=    the speed of the fade. Increase this for longer fade fades.

;   offset      :=    normally set to 0 but can be changed if you need to display the faded
;                     palette at a different colour offset.

As stated in the manual: For displays on non-AGA machines only #fmode0 and #loressprites are allowed
