Install MWCC compiler +The build system requires the use of the Metrowerk C Compiler 2.0/base to compile matching files. We cannot distribute the correct compiler here so join the PRET discord and download the pinned mwccarm.zip zip in #pokediamond and extract it to tools/. Run each of the executables so they ask for a license.dat and provide the one in the rar (it may also ask for it when compiling). This only needs to be done once. +In the future, a GCC option will be available so MWCC is not required to build, however it is required for a matching ROM. + +#### 3. Build ROM + +Run `make` to build the ROM.
