Nethack your DS
John Harris's outstanding, exhaustive GameSetWatch column, @Play, focuses this week on the topic of homebrew roguelikes for the DS. There are a few roguelikes available in retail format -- the Pokemon Mystery Dungeons, Izuna, and, soon, Shiren the Wanderer -- but those are all examples of the "Mysterious Dungeon" subgenre, and also cost money, which these homebrew versions do not (barring the initial outlay required to run homebrew.) And these games are the good kind of free, not the 'five-finger-discount' kind.
Not only does Harris provide a guide to different roguelike games for the DS, he kindly offers a guide to getting them on there. If you're a roguelike player, you may not be familiar with the concept of making things easier for yourself, but you may be able to adapt.
