Ultimate NES Remix

Ultimate NES Remix is a "best of" compilation of the NES Remix series and is the only installment of the series available on a handheld for the Nintendo 3DS. The game was announced in August 29, 2014 and was released in late 2014 in Europe, Oceania and the US and Canada and Summer 2015 in Japan, Hong Kong and Taiwan. Unlike the NES Remix Pack for the Wii U, which contains everything found in NES Remix and NES Remix 2, Ultimate NES Remix contains only challenges from 16 games pulled from the earlier titles along with two new game modes and a returning mode from NES Remix 2. Players who ordered the game by December 5 received a download code for a limited edition Famicom-style 3DS theme. Unlike most 3DS games, Ultimate NES Remix does not support stereoscopic 3D display.

Games
The challenges are almost the same as its predecessors. There are a few differences such as wording for the instructions. The players are also able to see regional rankings for games stages. The Remix I, Remix II, and Bonus stages from both games have been merged to accommodate for titles that were excluded from this compilation. These are the Mario-related stages:

Speed Mario Bros.
Just like NES Remix 2, Ultimate NES Remix contains a port of Super Mario Bros., but entitled Speed Mario Bros. this time around. It is almost identical to the original, except that it runs at twice the speed.

Championship Mode
Ultimate NES Remix includes the NES Remix 2 mode Championship Mode. The player faces three challenges, and the goal is to get as many points as possible. The first challenge is to collect 50 coins in Super Mario Bros., the second challenge is to collect 25 coins in Super Mario Bros. 3, and any remaining time is used to score as many points as possible in Dr. Mario.

Famicom Remix Mode
Exclusive to Ultimate NES Remix, this special mode is unlocked by earning three stars in every stage in the game. It includes challenges from the Japanese version of the game, some of which use different sound effects. Conversely, in the Japanese version, the North American version can be played as a special mode when earning three stars in every stage in the main mode.
