Increase buy in for Poker singleplayer

Has anyone been able to create a mod or alter the code to increase buy ins at the poker table? In single player, $5 buy in with a max possible win of $30 (with a full table) is getting old.

I've seen someone has made a mod where it increases your win after you leave the table, this seems pointless as you're essentially just entering a money cheat code. I'm more thinking you go in with $100 buy ins and are able to place massive bets in-game, to make the game feel more tense instead of how it currently is where if you lose, you don't really care about losing $5. Cheers folks!
