The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded.

Virtua fighter has a few massive polys that shouldn't be visible. It looks like these polys have a bad matrix, but the node distances are all zero. This means the bounding box that encapsulates them is of size zero. Skipping over these entirely seems to fix the issue.

The mipmap data in some games seems to being sent behind the base textures, and when the base textures are bound and created the mipmap chain is not yet valid in memory. To fix this, we invalidate the base textures, when the mipmap chain is updated.

Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :)

The hardware actually seems to treat the quad primitive as a triangle strip. The winding order can actually change between the first and second 'triangle' inside the quad, leading our code to incorrectly backface cull the 2nd triangle. So we must re-calculate the winding order for the 2nd triangle. This fixes a massive missing poly in the road in la machine guns, probably other games too. The hardware is unaffected by the winding order, as it doesn't calculate the poly normal from the vertices directly, instead it uses the provided normal in the poly header.

Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess.

The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space.

Non luminous polygons seem to be effected by the lightModifier also. API seems to have no restriction in this regard, neither does the SDK. The ocean hunter requires this for some of the 2d stuff. Light modifier values only seem to exist between 0-16, which is strange for 5 bits of precision. Possibly top bit disables the effect and lower 4 bits are the value. This clearly differs from the SDK, but without this the values come out clearly wrong.

Legacy renderer changes:
...
- Updated shading model. Unfortunately, it is far from perfect but it seems to be the best I can do for now. Not really much of a difference from before except that the Scud Race castle is fixed at the expense of the Yosemite level in LA Machineguns being too bright.
- Added lots of notes in the shading code.
- Passing both specular coefficient and shininess to shader. This will probably break specular lighting for now until the shader is updated to use the shininess correctly.
- Color table address in polygon RAM is now obtained from culling nodes as they are traversed (found this in the Pro-1000 SDK).

Previous 'fix' did not work for Magical Truck Adventure anyway and also broke some games (Daytona 2 transmission and course select screen, ECA title screen).

Rewrote 2D renderer and fixed 2D layer priorities, stencil mask clipping (Scud Race 'ROLLING START'), and cleaned up code. Unfortunately, the new code is about 50% slower, mostly due to the need to perform stencil clipping after scrolling.
