I've heard that the Turbo Everdrive has problems working on a unit with a region mod. Also, the doujindance units are the best out there and I'm thinking of getting one. Can anyone who's bought a region modded system from this eBay seller confirm that the Turbo Everdrive works flawlessly on one of his units? I know a few of you MUST have one of his. If you have an RGB modded unit, chances are you got it from him. I emailed him and he said that he has no knowledge of this cart so that's why I'm asking.
