There is only one way to rig dice and it is not with a program!
To do it you need 2 rollers facing each other
put a dicemaster/holodice showing a 6 on the rollers
get anthor dice/holo and put in on top on the rollers so there both in the same square
now put some lodge corners around it to hide the open bit (if using dicemaster)
when someone comes to bet
roll the closed dice and just before its about to stop pick it up
your left with your other dice showing a 6
