[Rijy]

Hi! First, thanks for taking the time to read this and help me out!

I am new to this...

I saw some people on youtube running snes emu and nes emu with a coverflow.

i want to do this but the emu i installed (wich i think is supposed to have covers wont work with my wiiu controller. Is it possible to use a wii u pro controller to play and a wii u controller to navigate in the emulator?
Also, is it possible to install the covers and the roms on my external hdd?

If someone could help me i would appreciate it

Again, thanks and sorry for being such a noob...

ps: i understand english but speak french so please try to be clear with the answers....

Thanks so much!
