Hi, I have a R4 Ver3 4GB kernal 1.21. when I initially set this up games loaded ok. Gave card to friend as she had cd's with games, these came with her card. now I'm unable to get mine working and neither could she when coping the games onto mine. I have since, removed files upgraded to 1.22 to no avail still getting the same msg. I also have an additional sys file after loading. help son's xmas gift
Format the sd card with panasonics SD formatter (free, use google to find) put the software back on to the card (fresh download is always advisable) put 1 rom (known good and working) try to use and see what happens.
