New CopyMem & CopyMemQuick patch

[ChaosLord]

Looks like some good work!

If you can beat Piru at coding, you have really done something!

I would be more motivated to install your patch if you supplied timing results from copying a 327680 block of ram.
That is the exact size of a 640x512x8bit AGA screen.  My game code sometimes must copy screens around.  Sometimes fastram to fastram, sometimes fastram to chipram.

After thinking about this in my head for 5 minutes...
I do not see how Move16 could possibly be legal on the Amiga.  In fastram or chipram.  It will corrupt any device that is DMAing into ram.

It might work on UAE since all UAE DMA is fake.  Actually the Move16 itself would be fake.

It sounds like you are saying your code will fail on any 060 or 040 that does not have an MMU.

Apparently Move16 is only illegal on Amigas lacking an MMU.

So if you have a 68EC040 or 68EC060 then you are screwed.
