ROM Hack mkds hack on m3 sd?

[Hydra_Hunter]

I have hacked my mkds rom (replaced course files), and created a rom from it, but im having trouble running it. How do I run a hacked rom (such as the mkds level replacement hack i did) on an m3 sd? Do I just copy it into the sd card, or do I have to pass it through the game manager? I've tried both, but when loading, it always gives me 2 white screens...

Try it on another cart if you have one. But sounds to me like you messed something up.
