Then do a full +opengl trace (i.e. one from the start of the program) and it
should be enough to start to look at what happens.

Well, if you want just to test if the application works better, just add
(stubbed) support for the following extensions:
= adding the string for the extension in the WGL extension string (no idea
if it needs to be duplicated also in the 'standard' extension string).
= adding all functions that are described in the three preceding extensions
(having them returning correct values) and printing debug output
= run the game again and see if it actually uses now these functions and if
it works better (ie better in 'not crashing', not better as in 'working'

For PBuffers, the WGL and SGIX interface is a bit different so an adaptation
is required. For 'render to texture', one needs to use
'GL_EXT_framebuffer_object' (or PBuffers) to emulate the extension.
So this is not the 'simple' thunking that most of the rest of the OpenGL
