The first thing to do is to ask yourself, "What do I want to do?" The answer to that isn't always direct. If you just want to screw around with the game and see how things work and what you can do, then there are two options.
(Preferred) Look through this tutorial and figure out how to do things, then try to make your mods.
Look through section 1 and then do whatever you want and don't complain if nothing works.
To use the Freeroam App., first download this program and save it to your My Documents folder. Then make sure that you have this installed to your computer. Next, follow these steps:
Double-click this icon:
Figure 1:
If you want to be able to walk anywhere, then make sure both TNG [blue in fig. 2] and lev (patched) [red in fig. 2] is checked, otherwise make sure TNG[blue in fig. 2] and LEV (unpatched) [Purple in fig. 2] are selected to make the program extract the levels like normal.
Figure 2:
Click File>>open. [see fig. 3]
Figure 3:
Go to your Levels folder, usually located at C:\Program Files\Microsoft Games\Fable - The Lost Chapters\data\Levels and click on FinalAlbion.wad, then click open. [see fig. 4]
Figure 4:
Click RIP! [see fig. 5]
Figure 5:
Go to your Data folder, usually C:\Program Files\Microsoft Games\Fable - The Lost Chapters\data and click Save. [see fig. 6]
Figure 6:
Wait about 5 minutes for it to finish extracting the files.
Close the Freeroam App.
Go to your Levels folder, usually located at C:\Program Files\Microsoft Games\Fable - The Lost Chapters\data\Levels and rename FinalAlbion.wad to FinalAlbion_.wad, or anything else. [fig. 7]
Next, go to your Fable - The Lost Chapters root folder, usually at C:\Program Files\Microsoft Games\Fable - The Lost Chapters, and open the file userst.ini [fig. 8]
First, download FableExplorer.zip from here and choose to open it.
Extract all of the files to C:\Program Files\FableTLCMod\FableExplorer.
Go back to here and download def.xml and this time save it to C:\Program Files\FableTLCMod\FableExplorer. When it asks to overwrite, click yes. If it doesn't ask to overwrite, you did something wrong, and you need to start over.
Fable Explorer will edit the .big and .bin files. It will also allow for .wad exporting, but I'll get into that later.
FE uses a linking system so that if two objects link to the same CDef (a property of an object) they will have the same properties. For example:
If you make five weapons with the same text enty, then they will all be called the same thing. Therefore if you change the name of one weapon, all the other weapons using that text entry will be re-named too, so always make new text entries. This brings me to my next point...
This is fairly simple. Edit already existing entries, rename the "Symbol Name", then save them in an fmp. Close FE, then re-open, and load the fmp. There you go! New game entries. There are other ways to do it, but this is by far the least time-consuming when you do several.
Expand CREATURE in your new window and click CDefs. Then scroll down until you find CHereoMorphDef. Look for blue text that says Links to (GameBINEntryID). Click that. [figure 12]
