Indefinite map scrolling in SB3?

The tile limit is probably enough for my purposes, so I'm asking more out of curiosity for now. Since the end of a map just gets cutoff, at least as far as I can tell, is there anyway to do indefinite scrolling like in Petit Computer?

I had a system that extended the limit before my SD died again. I had the map data stored in a 2D array (and maybe have 2 or 3 of them for the layers). Then I set up the BG layers being slightly bigger than the screen and keep track of the BG position in seperate variables so I can rerender the scene if the screen was moved. I'll try remaking it asap to show what I mean.

I don't know what your solution is But I glanced into, I think solid soldier's code, and it looks like it just kind of emulates the indefinite scrolling by using BGCOPY

Yes, that's actually it; you keep the scroll offset in a portion like BGOFS 0,32+X MOD 16,32+Y MOD 16 and at the edges of the BG layer, you feed new data. whereas the 32+ offsets the BG screen so you can also feed data on the left and top edges without the "seam" being on-screen
