These are the rawfiles that are required (next to iw4x.dll) to launch and play IW4x.
.iwd Files (iw4x_00, iw4x_01, ...) are uncompressed in this repo and need to be compressed before they can be used by IW4x, simply create a .zip archive of the contents of the iw4x_00 and iw4x_.. folders and change the file extension to .iwd.
Almost all the fastfiles in this repo are already compiled and available for use by IW4x. Likewise, as stated above, the IWDs can be built using the provided build scripts found under the scripts folder. However, some fastfiles are easy to reproduce, and to simplify development, the language fastfiles are built using OAT. The repository already has these files set up in the correct folders so that OAT can read them and generate the language fastfiles. See ci.yml for more information.
Used to convert fastfiles from the x64 game version to x86 for IW4x to be able to use them. It is licensed under GPLv3 and its source code for it can be found here.
