A decompilation project of New Super Mario Bros. Wii, based on the PALv1 binaries.

The build essentially consists of 3 steps:

All source files get compiled and the corresponding object files placed in bin/compiled/.

Since most of the binary does not have a corresponding decompiled source file, in order to produce a 1:1 match for the generated binaries, these parts must be extracted from the original files. The slices generates object files in bin/sliced/ from the slice information files in slices/.

All compiled object files and the remaining sliced object files are linked together to form the final object file, which is then converted into .dol or .rel.

alias_db.txt: Contains relocation helpers for rebuilding the .rel files.

syms.txt: Contains known symbol names for main.dol. Will eventually be replaced by a proper symbol map.

1. Obtain main.dol and the four .rel.LZ files from a dumped PALv1 disc of NSMBW.
2. Use tools/uncompress_lz.py to decompress the .rel.LZ files to .rel.
3. Rename main.dol to wiimj2d.dol, then place it and the four .rel files in original/.
4. Ensure that the checksums match:

$ md5sum original/*
17096d0ed441d44a0c31039138a8d7f8  original/d_basesNP.rel
f8cffd634edbec6c1bc210dab02c1e32  original/d_en_bossNP.rel
458f1aa94706dde1a8f2f9d97ff1f35c  original/d_enemiesNP.rel
393bf12ef4254dd1ea1366d5b06fbebb  original/d_profileNP.rel
ddab9e5dca53d8c18bf4051b927e822e  original/wiimj2d.dol

5. Obtain the CodeWarrior for Embedded PowerPC binaries from here and place them in compilers/.
6. Run ./build.py to compile the sources and generate the output binaries.
