Okay, I have an R4 and a EZ Flash V 3 in 1. I just started playing MegaMan ZX and read that you can access other bosses with MegaMan Zero 4 or 3 in the slot-2. However, I'm unable to make a save with Zero 4. Has anyone found a way to work around this problem? Maybe...if anybody knows where I can simply download a working save file?
