Well since I know there are 4 wrecks in the Texas systsem (all in those corrosive black clouds - 2 each.) i'll look for those.
I uncompressed the Li02-04 systems to find Texas, which is Li04.

From Li04.ini

If i recall correctly, this is a wrecked transport carrying Gate parts.

This is the wreck of a station and has Superconductor parts

Wreck of a Bounty Hunter ship, has some decent weapons on it (class6 Winchesters)

This is a pirate ship that was smuggling Diamonds, and gives a very nice boost to cash flow early on.

You should be able to find any of the wrecks by scanning the files for "surprise".

Thanks! "suprise" will do it!

Perfect! I wrote a smallish Perl script to remove wrecks from all the system INI files. If anyone wants it, lemme know. Thanks for the heads up, Xocyll!
