The item codes for the books don't apparently work anymore, although generally speaking the other codes (not item) work
They do still work, you just have to include the ' in the code, so it would be as follows
CLUAConsole:CreateItem('BOOK03')
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).
