Java vm mod

Hi,
i am looking for some help/instruction on where to start or how to modify a java vm file from pogo.com
I have a few others that others have made but would like to try this for myself. Any help or suggestions would be greatly appreciated. Basically i just want to get through the games quicker, have a bit of a play with the file and see what i can make it do.

Cheers
Bucks

1 probably illegal from pogo.com’s point of view
2 we do not condone any attempt to crack and/or hack games

Particularly since Pogo at least used to have cash prizes I’d say this was very illegal.

Also likely undoable. All the key logic to the games with prizes runs on the back-end EXACTLY so
cheater scum cant try to rip them off.
