Add argument check for the type in IDirect3DDevice8Impl_GetTextureStageState.
Does the attached patch help?
The game somehow queries all values for the Type(also not available ones) from
0 to 32 in IDirect3DDevice8::GetTextureStageState(), which seems a bit strange.
The problem is that the tss_lookup table has only 29 entries, which returns
random memory (or an access violation) in cases where the index >= table size.
The patch prevents this.
There might be another problem when WINED3DTSS_FORCE_DWORD is triggered (e.g.
Type == 0). So it could happen that there is also an access violation on read
access.
