Trying to run MelonDS just "softlocks" the system.

Installed it the way anybody should install an software, screen turns black wont turn on, moms spahgetti, this hurts. After fiddling around with the power button for a solid min, system turns on; thank god its not a brick but what the fuck I just wanted to play Advanced Wars.

This port is very outdated, and I wouldn't be surprised if it doesn't work on current versions of Atmosphere/Horizon. I'm working on a new emulator called NooDS now, but a new melonDS port is also being maintained here. If you want to run demanding games, the new melonDS port is probably your best bet; NooDS doesn't have a JIT recompiler yet, so it doesn't run everything at full speed.
