The screenshots above were not from GW. I have the equivalent of 5 SH3 installations on my computer. I just swap out the data folders when I want to switch "styles." The screenshots above were from a semi-stock version of the game. No changes except patch 1.4b and some of the major bugs fixed not fixed by the patch. The other installations include: complete stock version with patch 1.4b for backup purposes, a custom modded version with HT 1.47, a custom modded version with the unified NYGM campaign, and of course a GW installation. If I get bored with one version I simply switch to another.
