That's great news; thanks for the information!
I am considering trying it out with one of these wireless Logitech controllers.
Yes, you can use the TOM rev2 to play joystick games with your wireless Logitech 710 or rumblepad on the 2600. Just played defender on the 2600 and joust on the 7800 and it worked pretty sweet playing on the 2600 and 7800 with a gamepad. You may have to roll your firmware back to version 3 for the wireless 710, possibly the rumblepad. I tried scramble and commando on the 7800 and realized that you can only use one fire button, so no 2-button games. There may be a way to fix this, as the not-so-clear manual says you can use fire 1 and fire 2, but I haven't fiddled with it much. Maybe it is in mouse mode or needs to be set to default or something.
