Playing a Xbox game that is compatable with the 360 gives me an error

Thank you, I signed up for a live account not knowing its free and it worked, thank you so much.

So.. I have to have a Xbox live account to get the update to play the game?

Hi,

It used to be you could update just the BC list with a USB or writable CD, but I believe that avenue has been closed off with the discontinuation of official support for 360 hardware.

The only way I know of to update the BC function on the 360 is connect your old console to Xbox Live (yes, I know, not what you wanted to do). All you'll need to do is sign in with an account (any account), you don't need a gold subscription. Insert your original Xbox game disc and the console will download the file. It's only around 6MB.

As long as your hard drive is an official Microsoft drive the game will now run.

As long as you don't clear the console cache, the update will remain and you can play offline.

The current game is a backwards compatible game. In order to play backwards compatible games on the 360 you have to have an original MS Xbox hard drive. If you don't have a hard drive or it's a knock-off, it'll give you an error.

Wait, in your tags, it says "Unreadable disk". If the 360 gives an unreadable disk error, it means just that, it can't read the disk.

If you play an xbox game that is NOT backwards compatible, it will FLAT OUT SAY "THIS ORIGINAL XBOX GAME IS NOT COMPATIBLE". Not "this disk cannot be read".

Try cleaning the disk. Are there any scratches on it?
