Hello, I saw an article on GBAtemp saying that the R4i team came out with a product that allowed you to backup and over write save files of 3ds games. I though "hrmmm, that sounds... average" But, the article also said that I could get one free if I did a review for it. SOOOO, I sent them a overly polite letter stating my situation and me wanting to review one. Behold! they actually sent me one... now it's time to do my part of the bargain. Well, the thing is very big for anything USB but it was packed in a very small box. Upon open it up and putting a game in it I noticed you had to put the game in backwards, with I thought was odd. Once you put the game in, the cartridge protrudes out of the device about 3 centimeters. When I plugged in the device into the computer nothing instantly, and of coarse that's because you have to install driver software and a manager program... how retro...Oh...It also does NDS games, FYI. Now to the meat and potatoes. I've tested this device with Blazblue, SSF4, SM3dL. It seems newer games Have a different save format so SM3dL, Mk7, AND Need For Speed: the run (the poor children) don't work. Allthough the software will be updated to handle this. This is a device for thoughs who are paranoid and/or Filthy cheaters... but aren't we all? 7.5/10 STARS P.S. 3rd place I posted this review, thought I may as well.
