Do you think it's possible doing a DMA transfer from system mem to video mem
leaving the CPU free of doing something else in the meanwhile?
Some time ago I heard about this possibility for the screen update, but
someone said it's useless for many reason I don't remember.
Do you think it's possible and useful?
Please, give me your opinion and maybe some useful information about it.
