I'm following this tutorial. I have a gameshark, formatted the usb stick to fat using windows formatter. I created the exploit, finding the title id from the disc. All necessary files are on the USB. I copied the exploit to the 8MB Sony Memcard. The only difference is that he used Spyro, and I'm using Need for Speed Porsche Unleashed. Now my main problem is disc reading errors. I have two PS2s at my disposal. One is a Slim Model No. SCPH-79001 Date Code 7B Serial No. HU2335589 The other is a phat Model No. SCPH 30001 R Date Code 1C U0969346 The phat will read the Gameshark just fine, but for whatever reason will not read the PS1 disc. The Slim is just the opposite. I Copied the exploit with the phat, and tried to load it on the slim, but it just boots the PS1 game. I've gone over it all a dozen times, but have gotten so close only to fall flat on my face. I would really appreciate some help.
