When i bought my r4, and tried to extract 15 games from winRAR and only 3 games worked. It always says winrar diagnostic info: it is either corrupt or had an unexpected end to the archive. is this a problem with my r4, micro sd, computer, winRAR, or internet connection? (cause it is very slow) I have the newest r4 software v.1.18 or something. to pts
