Still Sanxion, running nice and smooth now.
Only a few games do just now, speed changes depending on the game.
Uridium and Sanxion both seem to be at full “smooth” speed. However there is still no input, and this WILL slow it down again…*sigh*
I will try and add basic input soon. There is no Sprite-2-???? collision. This would slow things downb a LOT!
There is also no drawing behind the background… same again.

Still, its here if you want it. it IS still a demo.
