Decompiling a Nintendo 64 Game in 84 Days

The original Snowboard Kids for Nintendo 64 has been fully decompiled in just 84 days, meaning all of its functions now have matching C implementations that produce identical machine code to the original. The significantly faster completion compared to Snowboard Kids 2 (which took 596 days) was attributed to the developer's prior experience, AI assistance, and community contributions, though understanding the IDO 5.3 compiler used for this game presented unique challenges compared to the GCC compiler used for the sequel. The decompilation is expected to help speedrunners and modders gain deeper insights into the game's mechanics and enable future modifications.
