# "S3DTK Error : SetState" from a stand-in S3D Toolkit

## Symptoms

The game stops with "S3D Virge Library Fail ! S3DTK Error : SetState" (or `CreateRenderer`),
or crashes in its clean-up right after `S3DTK_GetState`.

## Cause

The S3D Toolkit's functions disagree on success: `S3DTK_InitLib` returns 0 (`S3DTK_OK`), but
`S3DTK_CreateRenderer` and every function in the table it fills (`SetState`, `GetState`,
`TriangleSet`) return 1 (TRUE) (*observed*: `cmp eax, 1` after each call in `WPODS3D.EXE`).

## Evidence

The disassembly right after each call; the error strings next to the branches.

## What to do

Return 0 from `S3DTK_InitLib` and 1 from everything else. For `S3DTK_GetState` of
`S3DTK_VIDEOMEMORYADDRESS`, answer 0 and make `S3DTK_LinearToPhysical` the identity: the
offsets the game derives (`sfOffset`) are then plain linear addresses into its surfaces.
