...I think this GOG version DOES NOT allow the -badnews cheat...
Last time I downloaded and checked it, it worked and I'm pretty sure it still does.
You have to edit the game's shortcut properties and add -badnews in the target field, like
"C:\GOG Games\KKND Krossfire\Kknd2.exe" -badnews
Now start the game with the edited shortcut and while playing a scenario, hit Ctrl+Tab. Maybe there's a little delay, so don't hit it several times, but wait for "Cheats Enabled" to appear.
Yep, edited the shortcut as shown.
Still hammering away at CTRL + TAB, fast or slow, to no effect at all! "Cheats Enabled" just won't show!
This cheat just doesn't work!
Even Cheat Engine won't hack it..... how hard can searching for and hacking just one 4-byte value (for the oil amount) be? CE finds it perfectly OK - but just won't alter it - it's as if KKND2 has some hidden "anti-cheat backup value" somewhere that just overrides Cheat Engine constantly! Wargames European Escalation is the same with it's reinforcement points!
