How to get games into TI-86 calculator in any way?

I have the TI-86 calculator and i want games in it. I have another calculator TI-89 Plat and it has several games. I have the cable to put games into the 89 and i also have the cable for the 86 that you need to transfer from another calc. I have tried to transfer the games from the 89 to the 86 using the 86 cable, but it has not worked. There is always an error and i am wondering how to put the games in. Is there a special procedure that you have to do or etc.? Please specify how to put games using the 86 cable? (The only games i have are on the 89) Do i have to take the games from another 86? Thnx for the help.
