I made this mod after many searches and no success.
This is a simple mod to make the npc bet higher on Dice Poker

Instructions:
place at the ...witcher 2\CookedPC

If you already have a modded base_scripts.dzip, just Unpack using the Gibbed's RED Tools and go to "base_scripts, game, minigames" directory, open "dicepoker.ws" with Notepad++ or any other program you use, and search for "m_minStake" and change the value as desired for.

sorry for bad english.
