If you run the code while the blitter is active in parallel or a lot of bitplane DMA is going on then it may be fastest to simply do the mul (on 68k without fastmem).

It's enough if you add 32 pixel also on top+bottom of your planes (forgot to mention bottom before). Your display is only 320 pixel wide, so the 32 pixel bob can be shifted completely of of screen.

Yeah, on A1200 i would always prefer to clip instead.
Regardless A500 or A1200 it's a good optimization to never clip <=32 pixel wide Bobs because you usually have that space due to scrolling.

I guess the additional width was chosen to get rid of clipping Bobs on X axis as it makes blitter setup much less complex. I used that approach for 'Tinyus' and 'Wrong Way Driver' too.
