had the same prob yesterday. bits 16-31 seem to be mirrored 0-15,
bits 32-63 seem to contain bit 15.

Well, If you wanna just have identical data in the doubled sprites,
the way is this: Let the dma of the sprite on. the 64bit datareg
will be load correctly.

Then double it with manipulating the xPOS.

No way of more than 8 _different_ 64bit sprites thoguh :\

all afaik, if someone knows how to poke all 64bits, then tell please.
