When I set Mario Kart DS a donor rom and start Yu-Gi-Oh! GX: Spirit Caller it stops at a white screen. When I set Yu-Gi-Oh! GX: Spirit Caller as the donor rom it goes past the white screen but I get the "unable to read data please turn off and reinsert the game card" errorIn TWLoader's DSi Menu, move to a Mario Kart DS ROM, press SELECT, then select "Set as donor ROM".
