-
- I dunno (haven't done a doom game :) but it took me half an hour to convert
- Peter McGavin's old c2p4 (same applies to c2p8 too) to use modulo. In the
- fourth pass just write the actual blitsizh&bltsizv and use any bltdmod you
- wish - easy.

- There's no limitations. Why should there be?

-
- On 040s and with 040 optimized C2Ps the speed of the c2p is same than with a
- plain copy loop. So assuming a ~4 MB/s transfer speed to chip mem c2ping a
- 320x256 region should take approximately 20 ms.
