@toto2000 said in Which emu for ESPGALUDA 2 ?:

I thought that even 2D rendering could take advantage of OpenGL / Mesa 3. Fba uses that I think, for accelerating 2D rendering cycles...

It's not about being 2D or 3D, it's about being software or hardware rendered :

software renderer will render everything on a framebuffer then pass this to whatever backend is used for rendering hardware renderer will render the various elements using directly the gfx apis and let the gpu compose everything, meaning they are only compatible with the gfx apis they were written for

While it's totally possible to render a 2D sprite by directly using a gfx api, it was never done in either MAME or FBNeo.
