True, if you can ensure that nothing gets drawn in that area then there's no reason it can't be static. Fair point.

Yeah, for vertical scrollers it's always good to have as much vertical resolution for the game area as possible. If you're targeting PAL machines though, you can still have 200 pixels of space for...

Ah, that's interesting... What might also be happening here is that your X coordinate is also rounded to the lower 16 pixel boundary and the width extended to cover the shape (to the nearest higher...

It looks like your source shapes might have some blank pixels to the left of the shape as well, because it shouldn't erase more than the width of the shape (rounded up to the next 16 pixels). What...

I think it will always be a multiple of 16 pixels wide. Are you sure your shape isn't 17 pixels wide by any chance? Even if it's empty / transparent pixels...

If you're trying to keep the...

Yep, that shouldn't be a problem. When the game is won or lost, use CreateDisplay 0 etc. to switch to the menu screen.

You'll need to create a new display for that. You can do it easily enough though, just create the CopLists for the different setups you want, and use a CreateDisplay command to go from one to the...

Good stuff :) It's probably still a good idea to keep everything using the correct depth anyway (so both your bitmaps being 3 deep instead of 4), as it will save memory and might prevent strange...

Ah, I was barking up the wrong tree there, thinking primarily about the palette. You gave me a hint when you say that there are only ever 4 colours on the rear display...

Your problem is here:...
