I started this project back in March, got stuck, and quit. Then started from scratch Wednesday, and finished it up in the wee hours of Friday morning.
Select "Yahtzee" from the PSP browser (under Game->Memory Stick.)
At opening screen press 'X' to start the game.
Roll the dice with 'Circle'
Select which die/dice you want to hold with 'Up', 'Down' and 'X'.
After your third roll you will have to select where to score your final roll.
Select what category you with to place your roll with 'Up', 'Down', and 'X'.
Add highscore table.
I hope you all enjoy this game as much as I already have.
