I'm going to bite the bullet and buy an R4 at a shop for $64.99 US. Yeah, I know it's a crazy mark-up, but I need it now and all the major online shops are out of stock. My question is, how should I inspect the package to make sure everything is okay? If I insert the R4 into my DS without loading any firmware (I don't have a MicroSD card yet) can I tell if the R4 is working properly? Thanks in advance.
