Well, it seems I picked the right time to switch over to FSE This 1.5a version is really good! Including the compiler and precompiler files with FSE makes it much easier for people to use. Now you need nothing else, just FSE, very nice. It allowed me to point to my custom named fallout2.cfg (fo2xp.cfg), and knew from there where to find my game files in the source tree. If I change the cfg file to point to the game (dist) tree, FSE goes there instead (perfect). And the new post-compile batch file execution allowed me to add a copy of the compiled file to both my source and dist trees. Excellent! And I like how you have the procedure names along the right side of the screen for easy navigation within the script. So far it looks perfect, the only problematic thing is that it doesn't seem to do the "open file from dat". If I select that and point to a DAT file it always says "no file opened". This doesn't bother me because I always have a complete set of FO1 and FO2 extracted on my hard drive. Very nice work Jargo, and thanks for adding those new features. I'm using 1.5a every day now, and I'll let you know if I find any bugs.
