Original post: ndss.nl forum Download: U2DS Fw for R4 v1.11 (Should also work on M3 Simply) Person who did the hack: jeantje jeantje, from ndss.nl has hacked his way through the U2DS (DSTT Clone) firmware so it works on your R4. This way he claims alot of games that don't work on your R4, will work on this hacked U2DS FW. I myself haven't tested it cause i don't own a R4 anymore. Feel free to test it and leave feedback for him! This hack is used on your own risk and is not bugfree prolly, so don't blame anyone but yourself if anything goes wrong!
