Demo of my first game...

Looking good so far...but the display jumps from 262 scanlines to 636 when the game is reset. Could be that the INTIM countdown timer is not being given a value prior to this frame?

That would be because....setting up the initial screen you see when the game starts takes a loooong time.

 

I check for death during the overscan and, currently, just restart the whole game if you died, so, the flow goes:

 

VBLANK

Draw screen.

Overscan (Check for death)

If dead, restart game, which takes forever (apparently something like 400 scanlines) without VSYNCing.

VSYNC, jump to VBLANK.

 

Does that make sense? And will this cause problems; just ignoring the screen while I run a ton of code? It doesn't seem to...
