Nothing is wrong with the Xbox. Your disk is either dirty or damaged. Check the disk for dirt or scratches - either will cause a malfunction.
IT makes the other action replay codes work.
I think that Castlevania Symphony of the night is, but with 3.40, it's better to just doengrade to 1.50 and then use an emulator...tch, that was a mouthfull.

Go through the game from the start to the nugget bridge. Battle all the trainers there then go straight up and then as far left as you can then go down till you hit grass there you should find an Abra. Catch one, then go back to the top of the screen now walk down so your facing the trainer press start the second he sees you and teleport away. Then go back up nugget bridge fighting all the trainers to the left until you come to a kid that has a slowpoke. Beat him, and then teleport back. Go back to nudge bridge and a menu will pop up. After that, mew will appear. Follow these instructions. This works, I have mew. It will be level 7 when it appears, so try not to kill it. And also, have about 15 pokeballs, because, you will need them.
don't do that. I tryed today(11/29/08)and did not work.
That is a question of opinion. If you want to know what people who live near you think about video games, ask them. video games are a good way for people with uselless lifes to brake away from the chains of every day life and do some thing fun for a change (like fight a dragon for on reason). just kidding! not everyone how playes video games are losers. just a hefty majority. (like me!) well yeah video games are fun for most people but it depends on the kind of games you play. not all game are the same.
