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.

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.

Latest revision as of 18:38, 25 August 2015

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.

Description[edit]

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.

Shader program structure[edit]

When uniform values are set (in shm_uniformfv/shm_uniformiv), they are attached to the current shader program and stored into the corresponding shader program structure. They are later written to the GPU command buffer in __shv_validateShaderValidator or equivalent.

Shader program struct :

Offset Size Description
0x000 0x04 Value 0x0 ?
0x004 0x04 Program ID
0x008 0x04 Value -1 ?
0x01C 0x04 Pointer to program-specific uniform table
0x020 0x04 Total number of uniforms for program
0x028 0x04 Number of program-specific uniforms
0x414 0x04 Pointer to vertex shader struct
0x64C 0x04 Value for GPU register 0x0104
0x7C0 0x04 Bitfield containing dmp_FragmentLightSource[n].shadowed values
0x7D8 0x04 Bitfield containing dmp_FragmentLightSource[n].geomFactor0 / dmp_FragmentLightSource[n].geomFactor1 / dmp_FragmentLightSource[n].twoSideDiffuse values
0xA20 0x70*8 Table of structs for 8 dmp_FragmentLightSource

dmp_FragmentLightSource struct:

Offset Size Description
0x00 0x01 dmp_FragmentLightSource[k].enabled
0x04 0x10 dmp_FragmentLightSource[k].ambient (float[4])
0x14 0x10 dmp_FragmentLightSource[k].diffuse (float[4])
0x24 0x10 dmp_FragmentLightSource[k].specular0 (float[4])
0x34 0x10 dmp_FragmentLightSource[k].specular1 (float[4])
0x44 0x10 dmp_FragmentLightSource[k].position (float[4])
0x54 0x10 dmp_FragmentLightSource[k].spotDirection (float[3])
0x60 0x04 dmp_FragmentLightSource[k].samplerSP (u32)
0x64 0x04 dmp_FragmentLightSource[k].distanceAttenuationBias (float)
0x68 0x04 dmp_FragmentLightSource[k].distanceAttenuationScale (float)

vertex/geometry shader struct:

Offset Size Description
0x0 0x4 Pointer to shader code data
0x4 0x4 Size of shader code (in words)
0x8 0x4 Pointer to shader opdesc data
0xC 0x4 Size of shader opdescs (in words)

Proposed REing methodology[edit]

1. Choose a "uniform" you want to RE below

2. Take note of its ID and type !

3. Depending on whether its a float or not, go through the gigantic switches in shm_uniformfv or shm_uniformiv (non-float) based on the ID of your uniform (in the case of steeldiver: sub wars you can now just go directly to the handler as it's listed in the table below)

4. Once you find the piece of code specific to your uniform, take note of how the values passed to shm_uniformfv/shm_uniformiv are written to the shader object

5. Go through __shv_validateShaderValidator looking for where those fields written to in shm_uniformfv/shm_uniformiv are used and written to the GPU command buffer either directly or through __cb_writeRegs, __cb_multiWriteReg or __cb_fillRegs.

6. Document findings on 3Dbrew ! (that's the most important step)
