Not sure if I should post this on 2600 or 7800 forums. I have Tigervision's Polaris but it does not work in my 7800, not even if I remove it from the cartridge. I know most Tigervision games do not work on some 7800 models because of the cartridge shape. It worked (with cartridge) in a model I had like 20 years ago, but in this one it doesn't. Once I accidentaly inserted it backwards on the slot and then turned on, can it damage the game? Is there any way it can work again? Thanks.
