Sprite Ripping For World Maps

[skeddles]

So are there any programs that can rip world maps as you explore them? I imagine something similar to animget (which takes a screenshot every 10ms or whatever), but I need something that also patches it together for me. I tried using photoshop to automatically patch them together, with the photomerge tool, but it's really made for photos, not sprites.

So any tips? Or do I have to patch them together by hand?

Game is a PC game, so it needs to be a generic program rather than an emulator/rom related program.
