I think he meant if I try to blit bobs half inside the Bitmap, half outside, using the "technique" (I use the term loosely) I described here.

Which means I'll be showing the "outside" of the Bitmap.

I believe it will show up correctly but you'll be overwritting memory, so it shouldn't be done anyway.

I know you should split the BOBs to do this properly. Or you can have some extra bitmap room just to make the bobs "enter" and "leave" the screen.

OR you can just blit them entirely on screen. I've been "studying" some old games and I am surprised of how many games actually do that. Just show the whole sprite on screen when they enter it, and make it dissapear as soon as it touches the border instead of smoothly "Leaving" the screen. And usually in the middle of hectic action, the player won't notice.

Actually, by studying how some old games work, I am surprised by the amount of shit players usually "won't notice"
