well the ini file is kinda of complex, if im looking at the correct file there's alot of game option, i don't even know where to start to put the cheat enable = 1
Its not that complicated. Just add the following line (in a similar fashion you see it in the ini file) under the game options: 'Game Options', 'Cheats', '1', And you can activate the console by pressing Ctrl + Space (or Alt Gr + Space).
All BG and BG TotSC codes are included plus multiple BG 2 items codes (like amulet of life protection/proof against poison/warding/power, bracers of defense 3/4/5, leather armor protector of the second/Karajah's armor, weapons like the root of problems/wakizashis/ninjatos and many more things).
The book (manual) codes are the following: +1 Con - BOOK03 +1 STR - BOOK04 +1 DEX - BOOK05 +1 INT - BOOK06 +1 CHA - BOOK07 +1 WIS - BOOK08
If you use the CLUAConsole:CreateItem("BOOK04", X) cheat, you get X piece of +1 STR manual in one package (X is a number which is greater than 1). So if you add the , 5 after " of the item code, you get 5 items. Ideal to gain large amount of ammo (bolts, bullets, arrows), potions, scrolls or manuals with a single cheat.
