	The PICA200 is an ~~opengl~~ ES 1.1 compliant GPU manufactured by DMP. It comes loaded with a number of extensions that make it similar to an ~~openGL~~ ES 2.0 compliant GPU (ability to run programmable vertex/geometry shaders, for instance). Because of this, Nintendo wrapped GPU access into an ~~openGL~~ ES 2.0 implementation with some limitations. As the fragment stage of the pipeline is non-programmable, Nintendo instead gives developers the ability to configure a number of fragment-related values through glGetUniformLocation and glUniformXX. See below for the full list.		The PICA200 is an OpenGL ES 1.1 compliant GPU manufactured by DMP.

			== Other Symbols ==

			The list above is not exhaustive. A number of other strings specific to Nintendo's rendering framework have been found. Below is a table listing those strings including the location they were found in.

	This page's goal is to describe parts of Nintendo's OpenGL implementation for the 3DS as we reverse engineer it to better understand how to use the PICA200.

	Some of the information on this page is specific to Steeldiver : Sub Wars. The reason for this is that it's a fairly graphics-heavy game that's available on the eShop for '''free''', so it seems like a good target for a community REing effort.
