Hi there, I have a r4isdhc dual core "new" that might be fake. until recently, it worked well, except for the fact it didn't fit slot-1 well and it sometimes gave a hard time to plug it correctly. now, after ~4.5 years, I can't plug it correctly and thus it's unplayable. I tried cleaning it and using launchers, but the best thing I could get is invalid banner data in luma3ds. now, I want to ask: 1)is there any way to fix it? 2)if no, which flashcart I can buy to replace this card? I need: -SDHC 4gb mircroSD compatibility. -same firmware as my r4isdhc (wood) that can read my saves. -compatibility with ds lite. -compatibility with hacked 3ds (b9s, luma3ds) preferably with no launchers/loaders. -I prefer dsi 1.4.5 compatibility or at least hiyaCFW compatibility (I have DSi xl 1.4.5E with dsi browser and flipnote studio, so I can hack it when the hacks will be released. -of course, I want something cheap. thats the reason I posted this in r4 subforum, but you can suggest other flashcarts. -fit well ds lite and 3ds slot-1 thank you very much!
