It seems that fake R4 Revolution slot 1 devices have been released in China, and have been making their way to customers via unreliable online retailers. Unlike the original R4 Revolution, these knockoffs utilize cheap internal flash memory and are basically poor DSLinker/MK5 replicas being sold under the R4 brand name. However, the packaging is near identical as are the devices themselves, although the main difference is the addition of a small blue label on the fake R4 that indicates the amount of internal memory.
The R4/M3 team will obviously not be providing support or replacements to users who purchase the phony devices. Our advice is to be very careful if you’re planning on purchasing a new slot 1 device and to only order from a reputable online retailer.
