pokediamond/INSTALL.md

1. Copy baserom(s) into root folder

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

Linux

Building the ROM requires the following packages:

• make
• git
• build-essentials
• binutils-arm-none-eabi
• wine (to run the mwcc executables)

NOTE: If you are using Arch/Manjaro or Void you will only need base-devel instead of build-essentials or make or git. You will still need wine.

Also, if you are using WSL on Windows, please pass NOWINE=1 when compiling, and wine is not necessary for a WSL environment.

Windows

Before following the respective guides, please install devkitARM and ensure the DEVKITPRO and DEVKITARM variables are added to bashrc such that:

Msys2: export DEVKITPRO=C:/devkitPro export DEVKITARM=${DEVKITPRO}/devkitARM

Cygwin: export DEVKITPRO=/cygdrive/c/devkitPro export DEVKITARM=${DEVKITPRO}/devkitARM

You will still require the following packages:

• make
• git
• build-essentials

Install them using either the Cygwin package manager or using pacman on Msys2.

4. Build ROM

Run make to build the ROM.

Windows Users:

If you get an error in saving configuration settings when specifying the license file, you need to add a system environment variable called LM_LICENSE_FILE and point it to the license.dat file.
