Andrew Jenner created Digger Remastered. Maxim Sobolev converted it to use SDL. Sektor did a quick port of the SDL version to Nintendo DS.
This is a classic game originally by Windmill Software. You have to dig around the map and eat all the emeralds or kill all the hobbins/nobbins to pass a level.
There is no sound or music. There is a memory leak that will cause the DS to freeze after a while, it’s probably in Digger’s SDL video code.
If you have a DLDI supported FAT device, scores will be saved to digger.sco on the root of your card.
