User guide
How to use
Open the CTroll3D homebrew on your 3DS.
On Citra, access the menu option: Tools> Connect CTroll3D, and enter your 3DS IP Address.
Optimization
glReadPixels and VSync doesn't perform too well. So to increase the performance, please disable the VSync on Citra (and some other heavy stuffs like Accurate Multiplications). You can access these options in Preferences> Graphics> Advanced.
In some cases, the bottom screen mirroring can slow down your emulation, and should be disabled by pressing L+R+Down+Touchscreen (it can be enabled by L+R+Up+Touchscreen).
