i had the same problem, what i did that seemed to fix the problem (somehow) is to use simplePOPSTATIONGUI and customize the eboot, with a background or something and it then detected it.
There is another way where you change the name of the savedata but you will have to search afterdawn for that cuz it wasnt my method
Using popstation you can also edit the game save ID which is used for multidisk use!! make sure that all your eboot files are the same ID as the first and it should detect them, sorry if i wasnt much help but i found the way i did it worked
Click on Change Game Save and Game ID... write down what it says (probably something like SCUS-94163). Don't change anything, and exit out of popstation.
Now, open up your second EBOOT.PBP inside of Popstation and click on Change Game Save and Game ID. Change this one to be the same as your first one was. Then click on Go... and it'll patch the game for you.
Now you should be able to open your first disc data with your second disc!

until now i was trying just by changing the game save id, i will try now with also changing the game id and post back if it works
the game ID and game save ID both need to be the same as the first disc. the other forums just say game save id needs to be the same, thanx a lot XEnigmaX!!!
mine still cant work.. i changed the game and saved files id but when i load the data from disk 2, theres only a black screen.. but the memory stick light is flashing.. is there anyway to solve this?
