Hello,

confirming, still present.
This problem is essentially the same as bug 25423

I dumped the problematic part from the loaders "IAT" from memory:

00430560   2016C547  ; ASCII "gdi32.ChoosePixelFormat"

00430570   2016C574  ; ASCII "gdi32.wglDeleteContext"
00430574   20126351  ; opengl32.wglDescribeLayerPlane

You need wrappers for the following functions to get the demo to work:

--- snip ---
opengl32.ChoosePixelFormat
opengl32.wglCopyContext
opengl32.wglDeleteContext
opengl32.DescribePixelFormat
opengl32.wglGetCurrentContext
opengl32.wglGetCurrentDC
opengl32.GetPixelFormat
opengl32.SetPixelFormat
opengl32.wglShareLists
opengl32.wglUseFontBitmapsA
opengl32.wglUseFontBitmapsW
--- snip ---
