Hello,

it seems the demo uses its own loader/imports resolver (directly walks PE
structures).

Unfortunately it can't cope with forwarded imports.
The author probably didn't expect that Wine forwards some opengl32 API.

Partial dump of the loaders own "IAT":

--- snip ---
...
004300B4   7E61A912  ; opengl32.glColor3us
004300B8   7E61969C  ; opengl32.glAccum
004300BC   7E62259D  ; opengl32.glRectf
004300C0   7E61969C  ; opengl32.glAccum
004300C4   7E66C75C  ; ASCII "gdi32.wglCreateContext"
004300C8   7E6266B2  ; opengl32.wglGetProcAddress
004300CC   7E66C7EA  ; ASCII "gdi32.wglMakeCurrent"
004300D0   00000000 
--- snip ---

opengl32.spec:

http://source.winehq.org/git/wine.git/blob/658b048940e837e988487a64a4be3d4c6...

If you make small wrappers for wglCreateContext() and wglMakeCurrent() which
call corresponding gdi32 API using function pointers the demos will work.

The "magic" of 1K is actually a little shader snippet and of course squeezing
out PE header specs ;-)

Regards
