Hey guys! I am new to the ds dev scene and I am trying to get dualis working so I can use dslua with it. However, anytime i start dualis I get an error saying gpu_init failed. I hit ok and the program exits. Any help?

go into dualis.ini and change the GPU line to look like this

[GPU]
# OpenGL, D3D, GDI
Renderer=GDI

Thanks but still didn't work

Iirc, the only reasons for that error would be that you have a processor that doesn't support MMX or conditional moves (these have been supported ever since the PPro MMX that was released ten years ago), or that the gpu failed to allocate the memory it needs.
