XBox360: How can my son bring his character to another house?

So my son and his friend are HUGE into Castle Crashers. HUGE. It’s all they play (7 year olds). They like to play with each other whenever they can. Now, it is true that they can play online together but they only live 4 houses down from us and they like to be in the same room playing each other.

I can’t figure out what I need to do so he can bring his character over to the other kids house instead of using a second character he made.

I’ve actually got a memory card from back when the 360 first came out. Do I have to copy his profile on there? If I copy his save game will he be able to access his character off the memory card while his friend accesses his own character off the hard drive?

Hoe do I make this work?

First of all, if your 360 has the latest update you don’t even need to use that memory card. Any flash drive will do. Copy his profile from the 360 to the flash drive. Now you’ve got to find the save file for Castle Crashers and copy that, too (it’s important that you copy, not save- otherwise if something happens to the flash drive he’s lost his save forever). Just have him use that when he’s playing on another 360. Remember that he’ll have to update his old save on the original 360 using the new save on the flash drive when he gets back home.

Doesn’t he first have to sign in as his own Gamertag or something?

Would that be necessary for offline play?

Save files only work with the gamertags that initially created them.
