This can be done with the palette. You just need a lot of black (sky) and white (stars) colours in your palette. This means the tile can still be there but all its colours map to black and white only...

Despite of what may be claimed about AROS, it does _not_ boot on A600 or A4000 (or was it the A1200?) because of timing-related IDE-incompatibilities while there are no such problems when using...

I'm in the "2.5-inch-was-a-huge-mistake" camp. I spent 800DM in 1994 for a 330MB 2.5" harddisk. That was an insane amount of money. The A1200 had more than enough PCB real estate to put a 3.5" IDE...

You can always do stuff like dx += dx>>2 for a mul*1.25 if you have enough post-point digits.

The sound on the Paula video is just louder and probably more compressed than on the arcade video. The videos really are no basis for judging quality of the respective audio outputs.
