# New Super Mario Bros.: an early Nintendo DS matching decompilation

> nsmb reconstructs source for the Nintendo DS game New Super Mario Bros., with active comparison work on the US A2DE release. Its workflow extracts a user-dumped ROM, delinks modules and generates an objdiff configuration to compare reconstructed code with game code; a complete ROM build remains unavailable.
