I never done it really, but after looking it up, I guess its easy.
- You have to have be able to boot backups using swap magic or a modchip.
- Open WinRAR
- Browse to the folder the game is in
- Highlight the 1st numbered file with a single click
- Click 'Extract To..'
- Choose an extraction location, or just click OK
- Sit back, and wait for the iso to be extracted.
- Burn ISO file using Nero / Alcohol 120% to a blank DVD of good quality
I hope this helps.
edit: actually, I'll have to take back my words, its
not that easy. Most of the latest discussions on the
ps2 forum @ afterdawn.com are about this game.
