I've tried the glide mode of the Xengine successfully with OpenGlide (a glide to OpenGL wrapper, get version _009RC3 here:
http://sourceforge.net/project/showfiles.php?group_id=18883). I haven't tested any other wrapper so far.
You'll have to edit the openglid.ini to make it work properly. Here is mine, that works properly on my PC (check my signature). It has been generated by an older version of the wrapper, so it may not be compatible with the current version, don't copy/paste it, use it as a model.
Code:
Configuration File for OpenGLide
Version=Version0.09a3
[Options]
CreateWindow=0
InitFullScreen=1
EnableMipMaps=0
IgnorePaletteChange=0
Wrap565to5551=0
EnableFog=1
EnablePrecisionFix=1
EnableMultiTextureEXT=1
EnablePaletteEXT=1
EnableVertexArrayEXT=0
EnableFogCoordEXT=1
TextureMemorySize=16
WrapperPriority=2
FrameBufferMemorySize=8
I'm almost sure it wasn't with UHLE 2064, because I've tested the Xengine with PJ64 and 1964, much more than with the UHLE core.
