I do not recommend doing the swap trick just for Cogswap. I would just recommend to do the Swap Trick for ULaunchElf, then Boot the FMCB.ELF from there to install FMCB to your memory card. Kingdom Hearts will not work for swapping, as there is no .ELF to replace in the Disc. Also, is your PS2 a Fat (http://tenfey.files.wordpress.com/20...2420_440_1.gif), or a Slim PS2 (http://www.gocybershopping.com/images/T/t_1633.jpg)? Fat PS2s, in my case, have less security, so there is a wider variety of what you can swap. Slim PS2s have alot more security, hence very very very little variety of discs are allowed to be swapped. In this case, there is only 1 Disc that will work with Swapping on Slims. That Disc is 007: Agent Under Fire. It is very cheap, and you should buy it to do the Swap Trick if u have a Slim. If u have a fat, I do not recommend doing Swap Trick, IF you have a RETAIL cheat Disk, like Gameshark 2 or Action Replay MAX EVO, or Codebreaker that's a version of 8.1 or higher, and also 1 PS1 Game. If you have a Cheat Disc and a PS1 Game, there is a method to use the Cheat Disc to copy Custom System Configurations to your Memory Card, allowing it to boot something else when the PS1 Disc specified inside the System Configuration File is booted Normally. Otherwise, you will just have to buy 007: Agent Under Fire to Swap, regardless of a Fat Ps2 or Slim.
Hopefully this helped~!
