Hello there!
Sorry if this problem is also known, but i didn't find anything on google or the issues list which was similar to my problem.
I just downloaded Nintendont today just to use it with one game i loved ages ago (Super Smash Bros. Melee)
So the thing is: The game is working perfectly, no issues as long i don't turn on Memory Card emulation.
When i turn on Memory Card emulation, the game starts also, but the screen is weird, its flickering a lot, a few green bars vertically and i barely can read anything.
When i press the Home Button (to exit Nintendont), it loads back to the Homebrew Channel, but i just have a black screen with 3 vertically green bars.
Im using a WiiU (Pal)
The game ISO is a 1:1 backup (Pal)
Im using the WiiU Pro Controller
My TV is LED and supports Pal and NTSC
Using latest Nintendont Version (v2.298)
Also searched for updates from Nintendont's menu, where it said im using latest version,
but i downloaded it anyways in case there was an error while copying to my SD.
I took two pictures, so that you maybe have any idea...
