I have tried the Microsoft Entertainment Pack 2.0 for Windows CE with mixed success.
Installed through ActiveSync with no trouble
Chess - works
Codebreaker - appears to work, but doesn't quite draw the screen correctly after you try to guess the code. Doesn't draw the bars that give you the hints.
Freecell - No
Hearts - No. Complains about a missing file "pegcards.dll" I don't have it, do you?
Minesweeper - works
Reversi - works
Sinkships - works
Space defense - works
Taipei - works
Has anyone had any different luck?
