# Zoids Saga: Japanese GBA code reconstruction

> Zoids Saga One Decomp reconstructs code regions of the Japanese GBA game as C and assembly. Its verifier checks the user's ROM hash, compiles each listed region at its original address and compares the generated bytes with the ROM; the author reports 1,897 byte-exact regions.
