So far, I love my iEDGE. Mostly because it feels very similar to how the CycloDS is that my brother had. I have a DSi with 1.4U firmware so I needed to find another flash card that supported 1.4. I had a question that every now and then, more likely to happen after long periods of not playing DS, that whenever I press A on the Sudoku icon on the main menu of DSi, I sometimes get the message that "An error has occurred...", the same one that usually appears when you place a flash card that doesn't support 1.4 firmware and try to run it. Usually it's no big deal since I just restart and everything is OK. But I'm just curious to know whether the same thing happens for any other iEDGE owners or maybe EDGE owners too.
