I made a incredibly gigantic and complex map many years ago and the backup dvd of my ss stuff i made is nowhere to be found. All I have is a screenshot of my map in ssme. I thought i remembered it was possible to convert bmp to lvl, and I tried with FACTS but all i get is a teeny tiny section of my map in the output lvl file. I know the tiles will be messed up, dont care, would be incredibly hard to rebuild the map from scratch as it took me about 1 year in the first place.

Any help would be greatly appreciated.

Thanks!
