  "description_en": "sead is a decompilation of the engine and libraries developed by Nintendo EAD, now EPD, as found in New Super Mario Bros. U and other games. The README describes engine/ as the standard library, nw_ptcl as a wrapper around NintendoWareForCafe Eft, and agl as the graphics library. It says a byte-identical rebuild is out of reach without the NSMBU compiler, and the current goal is matching functionality and efficiency.",
