downgrade Indiana Jones and the Infernal Machine Indy3D 1.2 to 1.0 downgrade Xdelta patch.

This is a Xdelta3 patch that can downgrade Indy3d.exe from the GOG version of the game (Steam is untested but should still work) to the 1.0 version, which is identical to the one found on the retail release.

Users will need to provide their own Indy3D.exe file.

The purpose of this patch is to allow the digital distributions of the game to be used for the Open Jones 3D Engine which is an open source engine made for the game. Although the engine is compatible with the Steam and GOG releases, Version 1.0 of Indy3D.exe is a hard requirement to use the engine and can only be obtained from the retail release. This patch makes it so it can be obtained by downgrading the file instead.

How to use

1. Download and extract the xdelta file somewhere on your PC
2. Go to this Online Delta Patcher.
3. For "Source File" navigate to <path-to-game>/Resources and choose Indy3D.exe.
4. For "Patch File" navigate to where you extracted the Xdelta file and select it.
5. Click "apply patch" and download the new exe file.
6. Rename the downloaded EXE file to Indy3D, and navigate to <path-to-game>/Resources.
7. Backup the original Indy3D.exe first then replace it with the new EXE.

You can now use the game with the Open Source Engine by following the instructions on its GitHub page.
