ps2 - imports not booting

So I'm booting up a backup I have a of JAP NTSC game I just backed up.

It's called Blood+.

It boots fine then it goes past the PS2 Logo and it hits a screen that looks familiar to a "Insert memory card, blah blah"

But of course it's all in Japanese characters. I notice some numbers that correspond to how much space it wants, so I'm assuming it's something about a memory card.

I plug in my memory card, and try both selection options (both in japanese), but I can't get past that screen.


I'm using a DMS3 using the latest firmware and it does play import games (tho this and another are the extent of imports I've tried to play)
