OK... I always get the discs with the light green color on the bottom... gold and blue will not work on any of my PS1s... 5400, 7500, 9000, and a PSOne.... These include the Memorex from Walmart, Durabrand (I know, but they work great and are fairly cheap), and Tevion from Aldi's..... these are dirt cheap but my stations read them... not using them in the PS2 because I don't want to screw up my laser... but they all read in it as well.....
