Plus other players knew I had to be cheating to get the best word every time in just a few seconds. It was fun for about 2 days and then got boring because I always won so there was no challenge and thus little further excitement. Deja vu' - I recall using something like that years ago in online Scrabble - the independent program analyzed the tray letters and the board and came up with the highest scoring word to play so you could win an online multiplayer Scrabble game.
If I understand you correctly, you have an independent program XYZ residing in a separate section of RAM from game ABC once loaded, but which has calls from game ABC and feeds going to ABC (inputs from the game and outputs going to the game) all for the purpose of cheating game ABC.
