1024x768 and UP!
It's been my minimum resolution since 1995... At the time, I was using 256 
colours, but quickly upgraded to 16 (high colour), then 32 bits (true colour).

I have no idea how to help you. You might need to get Dev-C++ and 
recompiled it for your machine. What version of DirectX do you have?

I didn't need Dev-C++ to run it on windows, so I'll guess that isn't the
problem.

A quick check of the call stack for snowflake1.exe gave me:
ntkrnlpa.exe
ntkrnlpa.exe!ProbeForRead
ntkrnlpa.exe!KeReleaseInStackQueuedSpinLockFromDpcLevel
ntdll.dll!KiFastSystemCallRet
kernel32.dll!Sleep
hge.dll

The hge.dll is included in the zip, but it could be that WINE isn't
finding it. You might check if the Haaf's Game Engine can run under
WINE. The other files I think are ones that WINE should handle.

You need to get Dev-C++ to *recompile it from source* for your machine, 
if you were going to use the suggestion of recompiling.

Under WINE it indicates dx8 is being used, (but it is emulated so maybe 
just some missing functionality).  In my W2K VM, I show ... whoops, looks 
like I might not've installed any version.  Will fix that and try again 
in the VM.

The error message under WINE is:

err:wgl:X11DRV_wglGetProcAddress (wglMakeContextCurrentARB) - not found
err:wgl:X11DRV_wglGetProcAddress (wglGetCurrentReadDCARB) - not found
fixme:win:EnumDisplayDevicesW ((null),0,0x61f444,0x00000000), stub!
fixme:d3d:IWineD3DDeviceImpl_GetAvailableTextureMem (0x136bd0) : stub, 
simulating 64MB for now, returning 64MB left
fixme:d3d8:IDirect3DDevice8Impl_GetDepthStencilSurface Call to 
IWineD3DDevice_GetDepthStencilSurface failed

So this looks like a WINE issue.

Hopefully you can get it working, since I've got a new version almost 
complete. It produces more realistic snowflakes, and is based on an 
iterative function. Stay posted...

DirectX 9 on W2K now, no luck, though. :-(

Will do, hopefully the new version will have better luck...

Hi Sam,

Wow, this is really cool! It works fine, and the processing of 
snowflakes looks very beautiful. I will try out the bitmaps with povray 
as soon as I got some time.

Thanks! I'll be looking forward to seeing what you make.
