Knife trick boot should work, but it doesn't

[Devil N]

This is the situation:

I've got an unmodded PAL V3 PS2,
a recently bought PAL Action Replay V2,
a good knife tool for performing the knife trick,
a TV that supports NTSC,
an original PAL DVD game with a large TOC (Devil May Cry),
an original copy of the Asian NTSC-J version of FFX International.

Using the knife trick,
I can boot backups of my own original CD-based PAL games,
I can boot both PGEN and PS2Mame, which run just fine,
I can boot my own original DVD-based PAL games using a double swap with DMC.
The latter is for testing purposes only of course, I can boot original PAL DVD's without the need of the knife trick.

I figured that all this means I should be able to boot original imported DVD games. But FFX International does not boot. After the double swap and pressing X in the AR2, there's some disc activity and the screen turns black, but then nothing happens.

So my question is now: Where does it go wrong? What did I miss? It should work, at least that's what I figure, but nevertheless it doesn't.
Can I only boot backups of imported games? Or does my AR2 perhaps have some sort of limitation, seeing how it is a very new version? Or is it something completely different altogether?

Oh, and please don't tell me I should get a chip installed in my PS2. I'm looking into it, but it's very expensive here, so first I want to make sure there that there's absolutely no other way to do this.

Yep You Can ONLY boot backups With the AR2/GS2. the Neo2 dose not even boot Import Orginal.

Did you try to install cogswap? I have got a few DVD back-ups to play, so I would guess that you could also boot Import games. If you want to get cogswap. You would first put in the psx trigger cd, then after cogswap loads, put in the DMC DVD. After you wait for it to see you have a PS2 DVD in the tray, and hit [X] once. You should see a purple disc on the screen. Then you would knife the tray, and swap the import ( Do it fast or the load might fail ). Once you got the tray closed..hit the [X] button. If you need help installing or the setup of cogswap, just send me a email ( Or something :p ).

Here is what i would try burn cdloader then boot it with action replay/game shark then eject put in DMC toc disk then press x(will stop disk) then swap for import press x again

Umm, this is kind of an old topic by now. Swap Magic did the trick for me, and I've been importing more games than buying them at the local shop for over a year now. But thanks for the help anyway ;)
