Deleting games on R4-card ..

My son has a R4i card with 40 games or something. I have no problems with the card, firmware whatever, but he keeps - by accident - deleting the roms on the card and I can't figure out, how he does it - and he can't explain it to mm - he is only 4 years old.
Anyone who can telle me, how he does that, so I can show him what NOT to do?

more than likely (i used an original R4) he is on the game list, and is pressing "X" and then pressing "A"...the reason for this is because, "X" means deletes, and "A" confirms it....

Trust me, it is fun even for a teen like me, i once deleted all my games ;D

yep.the "x" button deletes a game :)but no worries: you still have your save files (but your son can delete them to with the mighty "x" button :))

Yep - that's what he did. And now he know's not to!
Thank you all.
