F-Zero X on Nintendo 3DS

The post-mortem of porting G-Diffuser, the F-Zero X decompilation, to the Nintendo 3DS takes place in two phases. The first phase, lasting 24 days, achieved 60 fps in 3D on a New 3DS in the summer of 2026. The second phase, extending 43 days, added Old 3DS support, a native renderer, and the Expansion Kit. From a black screen to a native-60 stereoscopic racer, the console underwent significant transformation.

The project involved a single director, a long-lived Claude session, and a total of 147 subagents. The final product was released in three console builds, compatible with both New and Old 3DS models with and without the 64DD expansion. The game includes various modes like Grand Prix, Time Trial, Practice, Death Race, and a machine editor, all featuring the real DSP music and effects, stereoscopic 3D, and a bottom-screen dashboard.

The New 3DS build maintains the native-60 frame pacing, while the Old 3DS build reaches a comparable result through a different method. The project took 43 calendar days from 09-07 to 10-19, 2026.
