Hi Gammel
Here's what I have after I unzip hsie's patch, inserted in a temp folder called "hsie patch"and after the SH3.exe has been patched.

Here's Stiebler's supplement unzipped into the sh3/MODS folder, the patched SH3.exe from the patch folder inserted in it
As you can see, there is a "Menu" folder at the top of the list vs. a Data folder in your example.
Here's the only two activated mods
HSIE PATCH
Supplement to V16B1 (JSGME)
When I activated the "supplement mod the Hsie mod greyed out.
These are the steps and in the order which I have done so far.
1. Unzipped Hsie patch to temp folder in Program File/Ubisoft
2. Inserted SH3.exe into Hsie PATCH
3. Click on Patch_SH3.bat
3a. edit en_menu & de_menu & Campaign_SCR as directed
4. Insert Hsie PATCH folder in JSGME
5. Enable Patch
6. Test game. v16b icon shows on rt lower corner/ingame WO immediately
goes to bridge upon surfacing-I am assuming this means Hsie patch is
working.
7. Unzip Supplement to MODS folder
8. Copy/paste SH3.exe icon from Patch folder.
9. Enable Supplement-Patch designation greys out as Supplement mod
overwrites as expected.
10. Test game-starts and runs normally but Supplement does not take.
I am obviously screwing up somewhere but......
Thanks again for the assistance.
Cheers!
H
