It looks like I do have the XML files, By version 0 do you mean a dump with no updates applied? I don't think it has any updates but I'm not sure, how can I find out?are you using the version 0 (extracted or dumped from your disc), or did you apply updates? probably v0 or else you can't use miimaker.
Do you have the XML files?
if you don't have the cos.xml and app.xml in the /code/ folder, loadiine uses a default value, but the default might not be good (it's not) for Mario kart 8.
if you don't have the xml, apply an update to get them and use SSB to launch the game.
if it's still happening, verify your dump is complete, or maybe your SD card is corrupted.
