Star Wars: TIE Fighter Cheats :
Cheats - Limited Infinite Ammo While Reloading
by Unregistered Apr 26, 2005
In missions where a reload vehicle is available, once it has docked and began the reload operation, you actually have unlimited rounds until either the "reload operation complete" message appears or the reload vehicle is destroyed. Once the counters in your ship max out, you'll have about 5 seconds before the operation finishes.
