New to hacking :( Having problems

Hello everyone and thanks for taking the time to read my post. I have a wii u i have loaded up homebrew and updated the store and luncher after booting up homebrew. I am currently trying to run SNES emulators on my wii U. When i go into the store and download the Snes2010 emulator everything goes good until i try and open it after installation. It will always freeze at the 95% mark of loading. I have tried also downloading it and manually putting it on my sd drive and same issue. I am wondering if it has anything to do with the fact i am using a micro sd card with and sd adatper to it? If anyone knows what i can do to fix this please help!! Thanks
