Well, I tried using an 800 grit sand paper to clean the contacts, and that didn't work either. I've tested the flash cart on my Turbo Express as well, and the Express does the same thing as my TG-16. I'm thinking that the American systems just don't react well to these flash carts. I wish the American systems weren't so problematic, even the American Duo has technical issues. The funny thing is that the flash cart worked perfectly the first time I placed roms on it, and only after subsequent switching of roms, did my tg-16 not feel like loading up the flash cart. Now, it won't even load up the blue flash cart menu screen at all. Has anyone had this similar experience as me, and if so, have you come up with any solutions?
