Import Backup Questions

[Marukka]

Hey there, I bought DDRMax imported from Japan, and because my crappy modchip (burn in hell sbox/neokey/whatever) won't play original PS2 imports, I have to make a backup of said game for it to work. But here's my question... How in the hell do I do that?

I've made the backup, and tried booting it from my GS2, but when I try booting it it will either A) Freeze at the Press X to continue, blahblahblah screen or B) It will continue from the press X to continue screen, the screen will go black, flash, remain black, and I can hear the disc wirring, but nothing is happening. So what am I doing wrong, or am I completely screwed in the situation? The PS2 is a 30001 (something to that extent) version, and I'm not sure about the GS2 version, it says GS2 V2 but that's all.

Any help would be appreciated, so here's my pre-emptive thank you.
