You can still use the Modern Warfare Xbox Live demo to pay FULL SNK games for free! Just tried it and it still works! 1) Download Modern Warfare 2 demo (it's open to both Gold and Silver members now). Start it. 2) Once the game starts, Press the center "X" button on your controller to bring up the menu. Go to Quick Launch and find an SNK demo you've already downloaded from XBLA (Samurai Shodown, Metal Slug, KOF, Garou Mark of the Wolves, etc). Start it. 3) You should now have the full SNK game! 4) Only catch is that the game resets back to demo mode once you quit it, so to play another SNK full version game you need to do the whole process again, but that's only 20 seconds anyway.
