Darkmar, when I make edits to a game, I only make edits to fix obvious problems. i.e. TIE Fighter original 3.5 disk version had a mission where a rebel Mon Calamari Cruiser was disabled and it never hyperspaced out. The secret bonus objectives you need to complete to be in the Inner Circle of the Emperor included the destruction of all the waves of veteran starfighters from the MCC.
In the collector's edition CD Rom of TIE Fighter, the IDIOTS who bought the rights form Lucas Arts made several mistakes, one of them was changing the 99.59minute hyperspace timer on the MCC to a 29.59 hyperspace timer. Apparently when they ported the game, they screwed up the game engine so that all the hyperspace timers were set to just under 30 minutes.
The thing about TIE Fighter, is that the game engine could not have an indefinite timer on the ships. All ships had a hyperspace timer attached to them. It was back during the days of Dos and Windows 95. The Lucas Arts designers knew this would cause problems, so any ship which would be forced to hyperspace out, would come back within less than 10 seconds. The idiots who reproduced the TIE Fighter Collector's CD Rom (was not Lucas Arts, it was someone else, despite LA's logo), didn't realize this. So when they went back into the game engine, in order to make it smoother with better graphics, they totally screwed up the hyperspace timer and reset everything to hyperspace out and NEVER come back.
The only way to beat the game on secret mission objectives is to edit the fouled up missions back to their original timer settings.
If my 3.5 disks hadn't have been corrupted I'd have made backups of them.
