I was looking to stream Bag Boy on ZeroPage Homebrew today but unfortunately it only displays a black screen when I start the game on my hardware. I suspect this is due to a initial unstable line count on the first frame when the game begins. Sadly I only have a suspicion of what's causing the issue but not how to fix it. :-(
I still have things I wanna do with the graphics to give a more varied experience. And then depending on how much space I may try to improve upon the simple walking movements and may tweak the playfield a bit. Overall I am pleased. Once I finish with the virtual Sprite behavior I am going to add power ups and bonus items.
