There aren't many games that run in high resolution but those that do tend to be pretty good. Coyote Dave's Poker is no exception, it's a beautifully presented game of poker - you play against five opponents with names like Slime and Tex.
Each character has his own personality and if you don't like them there are six more sets you can load in. There are sampled sound effects and an excellent help function. Plays a pretty mean game of poker too - ideal to practise on before tackling the real thing and separating your friends and their money.
There's also another version of poker, cribbage and Tetris on the disk.
