Eager to play Lemmings on your Nintendo 3DS? Thanks to bayleef. Lemmings 3DS is basically a clone of Lemmings for DOS. Fill the subfolders of /lemmings folder with data from DOS Lemmings (see README.txt files in these subfolders). These files are not included in the archive since they are protected by copyright law. In order to run the software, at least one subfolder must be filled. You may fill any combination of subfolders, depending on the Lemmings games you own.

Thanks to Nintendomax for the screenshot!
