Yes. I know what you're wondering, and thats not the case. I may have found out a way to boot DVD games with the CD version of Swap Magic. I have tested it with a few games and it works, but I need other people to confirm it! I think I've read somewhere in these forums that someone has mentioned this... but ah well. Here it goes:
Requirements:
A Ps2 (any will do I think).
Swap Magic CD ( I don't think the version matters, I use 3.6)
A real ps2 game DVD-5 (High TOC size is a must! Like Devil May Cry or Xenosaga 2).
CD loader (as a bootable disc).
A PS2 DVD backup game.
1. Boot the SM CD version
2. Boot CD loader
3. When CD loader appears, eject CD Loader properly (DON'T USE THE SLIDE CARD OR TOOL METHOD.)
4. Insert the real DVD PS2 game. The screen should load some numbers of the bottom like 4.37GB, when its done reading the disc.
5. Press 'X'
6. Screen will ask you, Boot EA method or something. Now you replace the game with your backup, using the Swap Magic method (I.E Slide card or slim tools).
7. Press 'X' again and the game should boot.
This is the best I can describe the method. As for the items, you'll have to find them yourself. Otherwise its all set. I think you can also use CogSwap or Zoneloader to do it, but I haven't tried it out. Oh yeah... I only found out this method yesterday after doing some messing around.
