So I recently installed TSLRCM 1.8.3 for KOTOR 2 on Windows 7, along with the M4-78 add-on. 
I've been playing through, and I just discovered that the means for entering cheat codes has been disabled. 
I tried using cheats on the first KOTOR, and it was fun. I saw some items for sale on Citadel Station and I want to buy them, but don't want to trek across the galaxy to get the creds. Long story short, I want to do a deus ex move with my in-game piggy bank. 
I went into the swkotor2.ini file and added EnableCheats=1 under the [Game Options] header, then pressed the tilde (`) key while in game, and nothing happened. 
What's up? Is this a consequence of TSLRCM, or the M4-78 add-on? How can I make the codes work again?
