As posted by Dan earlier, GWX comes with JSGME already included. Here's a few instructions to guide you through the installation of GWX 1.03.
I only add extra mods that can be enabled via JSGME.
Any mods you decide to add to GWX are added at your own risk
1.Uninstall SH3 via Windows' "Add/Remove programs"
2. Open Windows Explorer and:
- *delete* the folder where you had installed SH3
- *delete* the \My Documents\SH3 folder
3. Reinstall SH3
4. If your SH3 did not come with patch v1.4b already included, install patch v1.4b. Ensure you install the patch that corresponds to your copy of SH3 (Download/DVD/EMEA/US)
5. OPTIONAL: Copy and paste this "clean" install as a backup to avoid the need to follow steps 1-3 if your game becomes corrupt in future
6. Download theGWX.exe and the five .bin files. While there grab the v1.03 patch
7. Run GWX.exe and follow the installation prompts
8. Run GWX103.exe and follow the installation prompts
9. SH3 COMMANDER USERS: Download SH3Commander and download the GWX 1.02+ Cfg files for SH3 Commander and unzip the contents DIRECTLY into your SH3 Commander\Cfg folder.
