Come on Chris, i am lying to you man
i use it on my customers playstation from 5 thousand series all the way up to 9001 and ps1

it is called Wildcat Stealth 4 code, like i said on the other message reply, Mayumi 4 works too

this is all for NTSC, i can't speak for Pal games, Wildcat or Mayumi 4 don't work on PAL games, unless you have a international TV

i did extensive testing on Spyro 3 and all the NHL games PERIOD
