Note: Fallout 2 Save converter is a 3rd party program, so, Interplay, No Mutants Allowed web site, and other web sites that redistribute this, is entirely not responsible for any damage this program may cause.
ALWAYS make a backup copy of your saved game before trying this.

Description:
Fallout 2 is a game with lots of bugs. These bugs are eliminated in the next version, patch 1.02. Unfortunately, when you update your game, saved games made with version 1.00 are incompatible with version 1.02.
This is where this program jumps in. It'll make your 1.00 saved games to be usable with 1.02.

How to use it:
Just run the trans.exe file, select your saved game and press convert. Be sure to create a backup before doing this.
