- One of the probs seems to be the chip ram speed. Isn't it possible to turn
- on some sort of write-cache just when doing the conversion, and, when you
- realy need the data to be in chip-ram, flush the cache then. And, between
- c2p and cache flush, you could for example make up next screen, or
- something else...
