Mother 3 Fan Translation gets a new update, adds three years worth of bugfixes and improvements


Happy 15th anniversary, Mother 3. While the game still lacks an official English localization, the team behind the Mother 3 Fan Translation project has been working on an updated patch for the game. They've just released v1.3, which consists of just about three years of work done by lorenzoone--the person behind the Mother 3 Italian fan translation--that makes the English patched version of the game run and perform better in general. Some of the changes made include editing out typos, making it so that the game doesn't have slowdown while generating text in the overworld, prevents some softlocks, and other bugfixes and optimizations. As far as the fan translation's text content goes, it's "almost entirely the same" as before, but now it looks better than ever. You can download the latest patch over on the team's official website, in the source below.

Never played this series,
Is this game... .. Good? ?
It's a cult classic, for more than just "never got official English release". If you've ever played EarthBound, the gameplay is very similar to that - except improved in some important ways. Running is a thing now, and using regular attacks can be worth doing due to a new beat-based mechanic (if you can press the button in rhythm with the battle song's beat, you'll deal more damage, up to 16 times if you're good enough), the story is definitely more emotional than EarthBound's too.

If youre into the idea of weird quirky jrpgs yes. Mother 3 especially gameplay is definitely a secondary appeal to the world, storytelling and quirkiness even more than it was in earthbound. Common knowledge at this point but this series was the major inspiration for undertale.

Awesome! I really wish I could play it on GBA… but I never learned Japanese and still don't have a GBA flashcart.

Closest thing I can get to playing on GBA is using the 3DS. And that's what I'm going to do right now. *Sets avatar to Kumatora*

Thanks, for this article @Chary !
