pokediamond/INSTALL.md

1. Copy baserom(s) into root folder

Put a clean copy of Pokemon Diamond (US) nds rom at ./baserom.us.nds.

2. 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.
