XOR (CPC scene member)
From CPCWiki - THE Amstrad CPC encyclopedia!
XOR (Philippe G) was one of the best known and active crackers in the French CPC scene throughout the early and mid-1990s. However, his cracks of Titus Software' Super Cauldron and Prehistorik 2 were met with strong disapproval by the German CPC scene, who disliked the fact that he had cracked games written by a fellow member of the CPC scene (in this case, Elmar Krieger).
