# Kanken Training 2: matching reconstruction of a Nintendo 3DS executable

> Kanken Training 2 decomp reconstructs the Nintendo 3DS game's code.bin as C/C++ compiled with an ARM toolchain and compared byte for byte with the original. It records function analysis, matching recipes and checkpoint results. The author reports 2,832 accepted matching functions out of 4,545 creditable functions; readability work remains.
