actually no-cd cracks (exe) do not work as they should. therefore the "clones" are the best way to get a game running without using the cd.
i just ripped the cd with the standart settings: "ignore reading errors" and "read sub-channel data" (i dunno the correct terms for i use the german version of alcohol 120).
if you have problems getting jedi academy started with the clone (you can use the mini-image at
GCW as well) you should do the following:
# start the registry editor (start -> run -> regedit)
# go to the following location: HKEY_LOCAL_MACHINE\SOFTWARE\LucasArts\Star Wars Jedi Knight Jedi Academy\1.0
# apply the value of CDPath, Source Dir and Source Path to the emulated letter - e.g. if your standart cd drive is shown like E:, just change it to X: where X is the emulated drive (alcohol or daemon)
now you should be able to start the game without a cd.
hope this helped a little bit...
