Nope, you are not going to get a speedup here. memcpy() is written is assembler
and is pretty well optimized (and complicated). BTW, memcpy() and memmove() are
the same functions. There are no assembler block move commands for the 68xxx.
And I don't think you can use the DMA for this either. Don't know about using
the gfx cmds on the 68070 though? Someone else might jump in on this one. I
don't think that Kevin used any of those in his Kwindows code to keep it
portable (ie, for the 68340). I have no idea what you code does or looks like,
but in most cases you can achive better speedup results by improving
algorithms....

Well, not really. I've added it to my ad copy for the OS9 Underground. However,
stay tuned to you mailbox. I hope to have an upgrade announcment out to all
registered uses in the next 2 to 3 weeks. The upgrade will include Kved at no
additional cost (as does the current regular version).
We all look forward to the game! Some more graphics games are sorely needed for
the mm/1!
