I downloaded two different copies of this, neither of them work. On both of them, when I try to boot them, it says something like "cannot read save data file, try reinserting the game card." What does this mean? Is it some piracy prevention thing, and if so is there any way to bypass it? Or is it something else? Thanks in advance
Has been working fine on my G6 Real and Fire Card. Have you updated your firmware recently? Games like Zelda needed the R4 firmware upgraded, chances are the same upgrade would fix your problem. EDIT: Just tested on my M3DSS (latest firmware) and it works fine. (In case you don't know the M3DSS and R4DS are basically the same, so if it works on the M3DSS it will work on the R4)
I actually still had 1.09 when I tried. Right now I am loading 1.11 onto the R4, maybe that'll fix it.
