It's Nintendo Download time once again, North America, and this week is all about 3DS. Wii U, DSi and Wii all have a week off, though there's a mix of the old, the new and the even older to enjoy on the 3DS eShop. Let's get to the details.

3DS Download Software

HarmoKnight (Nintendo, $14.99) — A rhythm action game from the famous 'mon developer Game Freak, this has been high on some wishlists since it was teased in a Nintendo Direct broadcast last year. While its longevity may depend on your score-chasing habits, that doesn't detract from its overall quality and charm; check out our HarmoKnight review for the full lowdown.

Save Data Transfer Tool (Nintendo, free) — This app is linked to the recent system update and will allow you to transfer save game data from a game card to its retail download equivalent; it looks like this tool is part of a campaign to get 3DS gamers downloading more games direct from the eShop.

3DS Virtual Console

Legend of the River King (Natsume, $4.99) — The first part of a Natsume Game Boy Color double-header arrives in North America a little after the European equivalent, and offers up a blend of retro fishing with a healthy dose of RPG mechanics. If the idea appeals to you then this is certainly worth consideration, and our Legend of the River King review explains why.

3DS Retail Downloads

Sonic & All-Stars Racing Transformed (SEGA, $29.99) — Joining the download retail ranks not too long after its arrival in stores, this is the handheld port of the highly regarded Wii U racing title. While the content is all there, including fantastic track designs, the execution is poor with this one, and it suffers from a shoddy frame-rate and poorly optimised visuals. You can get all of the details in our Sonic & All-Stars Racing Transformed 3DS review.

Resident Evil Revelations (Capcom, $19.99) — Available for download more than a year after its initial release, this is a high quality entry in the franchise and an excellent part of the 3DS library; also available at a rather attractive price. It'll arrive on Wii U as a HD remake in the near future, but this handheld version shouldn't be dismissed lightly. We thought very highly of this when it arrived last year, and you can check out our Resident Evil Revelations review to see why.

Some good options to choose from on 3DS, though unfortunately other systems are left without this time around. So, what do you plan to download this week? Let us know in the poll and comments below.
