Does anyone know how to rip a whole map like https://www.spriters-resource.com/ds_dsi...eet/42514/ or  https://www.spriters-resource.com/ds_dsi...eet/29646/?
I've tried using an emulators view function, but that only displays the part that's currently on the screen anyway. I have the exact map files, but I wouldn't know how to convert them to images or anything.

Usually that's done by just walking around the map and taking a screencap of each part on the screen, then sticking them together in an image editor. The alternative is to rip the tiles and then construct the map from those, but that's probably much harder.

Ah, thanks for the answer. I was hoping I wouldn't have to do that, this is gonna be tedious :I
