blastar (./33) :
I updated 'DIFF' to v1.1
- no more tearing
- uses 2x20sprites (instead of 4x20)
- screenupdate triggered (saves some frames)

Great optimization Blastar! It looks that you were also able to increase the resolution and the window size.
Its nice to see that great ideas can be driven to even higher levels if the knowlegde of the right people gets concentrated on one spot.
To bad there is nothing meaningful to add from my side but this thread is always a good read anytime when I have quick look into the forum
