New ideas:

In TPengine a totally new approach: only differences are rendered.

The tiles to be updated are precomputed in HUGE ram buffer that holds the tiles to be updated for all the possible scroll position

Actually, pre computing all the scroll positions needs too much ram, but leads to optimal load balance.

I have to fine a way to precompute a frame at time....

About TPengine080924
The screen is "delta" encoded, all the copy positions are pre-computed and stored in a dynamic list.
Now the X position is computed on fly, thus the ram consumption is divided by 15.
The rendering engine restore an equal number of tiles of blocks at each frame
The code is still buggy but working, (the demo image is done to not show the bugs:)
