Compatibility issues

Skyline's way of initializing is not compatible with every game out of the box due to various reasons that can't be anticipated.

Mod developers might sometimes modify Skyline to make it compatible with a specific game which you should use if you are running into crashes.

Here are links to a few derivates (that you might have to build yourself):

• devkitA64.
• libnx - switch build rules.

This project is derived from OdysseyReversed and Starlight.
