You would have to recompile the engine. You need a brain, a UScript decompiler, and patience.

ah,ok. well i have a brain.  and patience. Whether i got enough of it will be seen^^

but where do i get a UScript decompiler from? i have been doing some reseach in the web already but havent found one. I hope you can help me.

edit: i think i have found a way (You are not allowed to view links.

edit 2: it does work i a way. but i get many files doing so. the new file "engine.uc" only containes something which appears to be color definitons. Where is the rest of the engine.u? or didn't i decompile it in the right way?

The way the cheat is setup; you can't use batchexport to export the classes. You'll have to use WOTGreal, or UTPT to export the classes into Engine/Classes folder. :_:
If I have some time, I'll just send it.

Yes, I have Wotgreal but I thought it would be to edit the *.uc files only?

It would be great if you could send me that
