Nope, some brilliant individual managed to rip the ISO files for both games early last summer. I've only played the American version of this game once upon a time, so this was a nice turn of events.

Anyway!


It turns out that all I needed to solve this little problem of mine was a new SDHC card with a higher capacity of 8GB( as opposed to the regular 2GB SD card I was using previously )in conjunction with unzipping the RAR files straight off of my desktop, rather than trying to build the folder structure myself( which is obviously why it was failing ).

With this correct folder structure and extra space put to use, both Mario Kart Arcade GP and Mario Kart Arcade GP 2 are working beautifully.

Many kind thanks for everyone's attentiveness to this problem.
