As I explained in another thread, the more modern versions GWX-SH3 (GWX 1.03 and later) crash because of a wrong ship ID-value for the Ammonition ships in the mission files. Explained in the very first post of Raduz's hydrophone thread:

However, since you don't have GWX you can't use it anyway. GWX completely modified/re-aranged the ship database, adding alot of other ships. It simply won't work on Stock sh3.
