Tried it out on a real 1200 (030@40mhz). Pretty impressive but does slow down quite a lot when blitting the big bobs - don't see so much slow down on bullets so if your intention was to create a bullet hell engine - looks a real possibilty.

One thing i have notice through my own efforts is that winuae seems to blit faster than a real Miggy (it may be a setting I have to change in Winuae) i.e. I have a working Doodle Jump engine which seems fast enough when tested through Winuae (and I do limit processor speed etc.) but is slower on real hardware. This is where sprites v bobs comes in...

I found an interesting sprite routine a while back (might have been here?) which might be worth investigating for more speed? It's call bb2vspr and can be found on the Aminet:

Just download the Blitzlist and unzip.

Keep up the good work!!!
