Project Setup

1. Clone down project

git clone https://github.com/zeldaret/tp

3. Download GC_COMPILERS.zip from the Discord server. See the pins in the #tp-decomp channel under the Twilight Princess group.

4. Extract GC_COMPILERS.zip into the previously created mwcc_compiler directory

unzip GC_COMPILERS.zip -d tools/mwcc_compiler/

5. Place a copy of NTSC-U GCN Twilight Princess in the root directory and call it gz2e01.iso (find this on your own)

6. Setup the project

./tp setup

Building The Game

make game

The completed build is under build/dolzel2/game/sys/main.dol

Build DOL

(Note that any time you run make you can add the -j# argument where # is the amount of threads your system has in order to greatly speed up build times)

Build RELs

make rels

The completed RELs will be under build/dolzel2/rel

Extract Game Assets

make assets

Create Expected Directory

./tp expected
