Here is a quick port of Wolfenstein 3D based off the SDL port and using some code from my other Nintendo DS port.
A few notes:
------------------
1) May still be a few bugs
2) No sound
3) No music
4) No saving
5) No loading
6) The analogue stick is used for movement, even in the menu
You can redefine the keys if you don't like how it's set to by default, just check imap.txt to see how it goes.
If you do find a bug, let me know so it can be fixed.
I have tested this on firmware 1.5 (emulated) and through the 2.71 XMB with the latest homebrew enabler.
