Friend is having problems swap-loading a game

[Jersiah]

Hey, I said I'd help my friend out with this so I'm posting for him.

He recently got the DMC3 demo from Japan and I told him he couldn't play it on an American ps2, he didn't wanna get a modchip, so I told him there was a swap method also. He got the slide card but his gameshark is Version 4 and pops the tray when the game loads so the trick doesn't work on it. He says he also tried an Action Replay and that didn't work either.

What could he use as a boot disc of sorts, where he could put in an original game, do the swap trick to put in the import demo without ejecting, and load it?

If it helps, he has a Version 7 PS2, Model # 39001.
