I installed a crystal chip and can't get the flash screen to boot on the ps 2 v 15. It just a black screen. I put in a orig. game and it worked fine, after trying to boot the flash screen a few times, now it wont even play the orig game. I tried loading a upgrade cue in and nothing. The file seems kind of small 2K, am I unzipping ir correctly off my the computer, you would think the file would be biger? Any help please.
