Solitaire

This may sound like a silly suggestion, because just about every Windows PC has solitaire on it, but what about a portable solitaire game.

I am thinking about attempting make Big Solitaires 3D portable.

Name: Big Solitaires 3D (40+ Solitaire Games in 3D)
License: GPL
Website: http://sourceforge.net/projects/big3dsol
Registry: None that I can see.
Size: 4Mb
Dependencies: OpenGL, Win32 (MS Windows), GTK+, wxWidgets

I am pretty sure it either has an Open GL renderer or requires Open GL. Would that make it non portable?

I can't tell if it requires Java or not it say it is written in C++.

Under user interface on the Sourceforge page it says:OpenGL, Win32 (MS Windows), GTK+, wxWidgets.

Used universal extractor to unpack the installer then launched it from that folder. Seemed to work just fine and write no settings to the registry.

Any thoughts?
