The future is looking bright for those of us A1200 owners who want a 68060 but don't have one yet. Between the TF1260, the Warp 1260 and the ACA 1260 we'll be spoiled for choice :)

Oh, that does change things a bit yeah...

Better option in that case is probably to switch base colours a bunch of times during the screen. But at any rate you won't get a full 24 bit set then.

If you do, keep in mind that Dual Playfield bobs are either 3 or 4 bitplanes deep (OCS/AGA), not 6 or 8. I made that error once or twice and it made everything seem much less nice than it was :D
