Can't play Xbox 360 games on series x

So I can't even play the game on my Xbox series X controller without the guitar also I can't play the disc version on my Xbox series X

You can still use external HDD for your Xbox/Xbox 360/Xbox One games but you can't play Series X/S games from them,

Series X/S games can only be played from the internal or external storage card,

with game file size's getting bigger, that 1Tb internal NVMe SSD is going fill up quick.

Hi,

Where did the Xbox 360 games come from? Another Xbox 360?

If they were downloaded via an Xbox One/Series console you can't play these games on an Xbox 360. Firstly the drive wouldn't be configured for an Xbox 360. Secondly, Xbox 360 games downloaded via an Xbox One or Series X|S are actually 360 games that have been converted to run on an Xbox One, they are no longer native Xbox 360 games.

Yes, if you purchase the game from the Xbox 360 marketplace, you can play it on the Xbox 360, Xbox One or Xbox Series X|S.

As for what Hardcore Games said, you can still buy Xbox games for the Xbox 360, and play them on the Xbox 360, and if they are backward compatible, play them on the Xbox One & Xbox Series X|S.

Hello there,

every Xbox 360 and or Xbox one game you can play via backwards compatibility on your series X/S share the same multiplayer network, so yes you can play those games with your friends across different generations of Xbox. However for future games releasing
on Xbox one and series X/S separately, I can't confirm that it will work a 100%.
