# New Super Mario Bros. Wii: matching decompilation of the PAL game

> This decompiles New Super Mario Bros. Wii from the PALv1 binaries. A dumped disc supplies main.dol and four rel.LZ files. tools/uncompress_lz.py decompresses the rel files. main.dol is renamed wiimj2d.dol and placed in original with the rel files. The MD5 of wiimj2d.dol is ddab9e5dca53d8c18bf4051b927e822e. CodeWarrior for Embedded PowerPC goes in compilers/Wii/1.1. ./configure.py then ninja links a dol and rel files that match the originals. ./progress.py --verify-bin checks them. Linux and macOS use wibo or Wine.
