Fishing sprite glitch

 Infinite Money  To perform the Fishing Sprite Glitch in Harvest Moon DS, all you have to do is hire the fishing sprites in Winter to fish at the Beach. There is a chance that you will end up with billions of G in-game, when you get paid.

This has been patched in Harvest Moon DS: Cute.

 Corrupt save files  On rare occasions, saving while the fishing sprites were active would result in your save file becoming corrupt and unplayable. This doesn't work for HMDS Cute and HMDS European version, or NA version but earlier version
