You're right, the original emulator source code (SDL chip8) is not distributed under GNU license, but under a kind of copyleft agreement :

Here is the original hearder :

Code:

/*This is my first attempt at writing a complete emulator
  most of the code has been taken from a previous attempt of mine
  that was intended to use Allegro but I never learnt how to use that libaray
  anyway it is a chip8 emulator which is programmed to make
  use of openGL and GLUT, the purpurse of writing this emulator
  is to learn how to use openGL, GLUT, to write an emulator and
  to furter expand my c programming skills and knowlage please
  feel free to use bits of my code, all I ask is you give credit
  were credit is due, TJA.

  FEB 11, 2003. */

So, Zion can do what he wants with it (and port it to PSP for our best pleasure :P) , but i'm not sure he can release it under GNU license without the agreement of TJA
