Pokemon TCG Online

This question appeared to have some fruitful answers. Apparently you can't open and edit them as such, but you can view them, which may allow you makes screenshots and then put them in a sheet.
The 2nd answer has a link to a web application to open them (which requires Unity Web Player), while the 3rd has a downloadable application. I'd recommend giving these a go and see if they can open your files.

I would give test them myself but I don't play the game. However since it looks free (to download in any case), I might be able to help if you happen to have any issues.

thx for the answer!
hmm so you can only view them...
ahh well better then nothing! ^^
i tried the downloadable application and it looks like it dont recognize the files as ".utility3D" files...
and by the 2nd answer i dont know how i should upload the files there...
it looks like you have to enter an url but i have the files on my pc...
ahh and yes the game is free to download & play...
you can buy booster packs but only if you want... ^^
but it looks like without buying booster packs its almost impossible to obtain all cards so i need to extract the cards from these .unity3D files to get all cards with their correct size...
