While Ni Nu Kuni was released for the first time on the PS3 in 2011, it's easy to forget that there was a completely different DS version of the game that was released in 2010. Mostly because this game was only available in Japan.
No Kuni: Domain of Darkness Jin was mostly based on the same story, but was built from Nintendo's hardware base and played as a totally unique experience. Even come with a huge book of spells that is designed to be on hand while you play to know how to throw them.
It takes eight years (until the day, as the original, and this version is on December 9), but a team working at GBAtemp (through Bya @ Resetera) has finally managed to build a complete fan-building building that has already is available for download.
Moreover, they even translate the spelling book so you can print it and have it with you.
Here you can download the translation. I remember that I was so excited about this game that I got the Japanese version and tried to get her to do it without it, so I'm super excited to try this.
