Extracting .epk files

[MightyCucumber]

I'm sorry to bother you guys, but this isn't Metin 2 related - however, since the only reference I found to an .epk extractor was from the Metin 2 community, I'm hereby asking for a bit of help. I think only you can help me, since this is the only place I've found reference to such file extension, and ways to extract it...

I want to open an .epk file contained within another game (Stunt Cars for the WiiWare if you're wondering) but so far Ive had no luck finding anything capable of extracting the files - namely the car models and textures. My plan is to convert these to Revolt, a game which some of you might be familiar with.

Here's the donwload link to the said .epk file, in case you are wondering -

Thank you in advance to anyone who's willing to give me a bit of guidance, and sorry again for asking this here. I really want to convert these cars, and you'll be given credit for your help.

Cheers,

Mighty.
