 |  Re: VB interrupt. How do you get it to trigger?
I was a little concerned about unrolling the code as in reality there is much less than 16KB available.
2K for colour map and screen map screen 1
2K for colour map and screen map screen 2 (Double Buffer)
2K Character set
1K Zero page
Probably 1Kb for music and fx.
Leaves about 8KB.
Now I'm quite good at condensing stuff down to the essence but there are limits 
It's interesting that reviews of C16 games make reference to things like "There's no title page".
With 8KB left I'm not surprised. The character set for my title alone take 37 characters.
That's fine for something like a C64 with abundant memory but not for the C16.
