A minor quality-of-life fix: In Rev 1, moving furniture in the Mii Apartments editor had a 0.5-second input lag. Rev 2 reduces this lag to 0.1 seconds, matching the responsiveness of the Japanese version.

Dutch (Nl) text strings in Rev 1 were notorious for overflowing text boxes because Dutch words are often longer than English or French equivalents. Rev 2 shortens certain Dutch UI strings (e.g., changing "Aanbevolen geschenk" to "Cadeautip") to fit perfectly without truncation.

In Nintendo’s internal naming convention, "Rev" stands for Revision . The first batch of cartridges pressed for Tomodachi Life in Europe is technically "Rev 0" or "Rev 1." The label indicates that this is the second post-launch update pressed directly onto the game cartridge.
