git clone https://github.com/Nenkai/GT4Hooks
cd GT4Hooks
mkdir external

git clone https://github.com/ThirteenAG/ps2sdk
cd ps2sdk
git checkout fcb813152116579e7a44e800d64e17185f4c27b5 .
cd ../..

Then:

1. Get GT4ElfBuilderTool
2. GT4ElfBuilderTool.exe CORE.GT4 BASE_SCUS_974.36 - You should have BASE_SCUS_974.36 after this. Copy it to the main directory.
3. Get ps2plugininjector, copy ps2plugininjector.exe to the main directory.
4. build
5. You should have SCUS_974.36.elf, ready for use with PCSX2.

When using it with PCSX2, ensure to link the original iso to the executable (Properties -> Disc Path).

You may also need to re-enable HostFS in Emulation -> Enable Host Filesystem everytime you rebuild the elf (different hash).

NOTE: If you get Unable to initialize device PRN when building, make sure that ps2plugininjector.exe & BASE_SCUS_974.36 are present.
