I always miss the way Amiga's dealt with volumes and especially the assigns. Such a useful way to order your files beyond just drives and directories.

Ah, of course!
It's just that the bitplanes are delayed by x pixels when using BPLCON1, this hasn't changed from OCS/ECS. Only the maximum delay has. So if you delay by 64 pixels and have a DDFSTRT...

Yes, it might be useful to know why you've not actually noticed any problems. The reason for that is that your example doesn't actually show any bitplane GFX in the left most part of the screen. The...

When you talk about pseudo 3D, what's the difference between these and say Lotus 2?
The way the road is done in 'chunks' rather than lines? Or is it something else?

I think the issue with JP's parallax is mostly that it's too bright and it also might move a tad too quickly.
