[Mono-list] Porting FreeTrain to Mono

[Atsushi Eno]

Hello,

So I've created a patch to make it build with mono (from FreeTrain.sln, 
built with MonoDevelop). Though I
could not get it run fine on mono due to some SDL_Image_Load() 
behavioral difference that returns null.

atsushi at linux-tx2c:/svn/FreeTrainSDL/bin/Debug> MONO_IOMAP=all mono 
--debug FreeTrainSDL.exe
Unhandled Exception: System.ArgumentNullException: Argument cannot be null.
Parameter name: src
  at (wrapper managed-to-native) 
System.Runtime.InteropServices.Marshal:PtrToStructure (intptr,System.Type)
  at SDL.net.Surface..ctor (System.String filename) [0x00052] in 
/svn/FreeTrainSDL/lib/SDLGFX.net/Surface.cs:99
  at FreeTrainSDL.SDLGUI.initGUI (Int32 width, Int32 height, IntPtr pf) 
[0x00067] in /svn/FreeTrainSDL/SDLGUI.cs:61
  at FreeTrainSDL.FreeTrainSDL.Go () [0x0011b] in 
/svn/FreeTrainSDL/Program.cs:120
  at FreeTrainSDL.FreeTrainSDL.Main () [0x00006] in 
/svn/FreeTrainSDL/Program.cs:79

It would be nice if someone who is familiar with Tao/SDL could try it.
