My son upgraded his DSI a while ago, and i have only just got round to sorting out why he can't play his games on R4I card, i see you can use an alternate DSI to fix his R4I card?

I have a DSI that's running version 1.4e?

Will i delete all data on alternate DSI by performing upgrade option with 1.4.2 kernal provided by r4i-sdhc, or does this upgrade just update R4i card only?

Kind Regards,
