after a lot of interference from the real world and a lot of changing of my mind I have made some progress on the Parsec 2600.
that is my tech blog and here are some youtube videos of the meteor and single enemy with scrolling
1 enemy scrolling test
1 enemy attack test
I programming the thing in 16k multi-sprite kernel. The multi-sprite kernel does not allow sideways scrolling so i'm doing a lot of slight-of-hand to simulate the look of sideways scrolling.
why I didn't use the other kernels is the standard kernel did not allow multiple items on the screen, which killed the swoopers. And the DPC+ kernel kept getting overwhelmed and crashing.
I still have the swoopers to do, which I already have the code in the DPC+ and standard kernel and just port over. then the tedious task of gluing the whole thing together which will take a while.
update: I think I just came up with a viable way to do a refueling tunnel. will preview soon.
