Hi! I'm not sure how accurate the list is you linked as these two others I found don't list the game as backwards compatible:

Delete the game, clear the console cache and download the game again

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

I am a gamer and independent advisor on the XBOX community platform.

Hey Laith49, how are you today? Hope you're well.

I am assuming that you're trying to download them from Xbox Store in your console, not from any external hard drives.

Try this on your console:

First, clean the cache of your console that way:

1. With the console turned on, hold the XBOX power button on the console for 10 seconds until you hear a small sound.

2. Wait 10 seconds.

3. Turn it back on.

Note: It may take a while for it to turn on, don't worry, it's normal.

Then, restore your console keeping the games and apps:

***IMPORTANT*** If you share accounts with someone, you will have to redo the process of placing the account as the main one again, be aware of the chances you still have to do this, as Microsoft makes available per year, only 5 chances so you can make some account your console's main account. Make Sure to know all passwords and email addresses of your accounts, you will need to log then back in.

1. Press the Xbox button to open the dashboard.

2. Select System > Settings > System > Console Information >

3. Select Reset console > Restore and keep my games and apps.

4. When asked to pull settings from an old Xbox, choose no, thanks

5. You will have to log in to your accounts again, and when you sign in with your account, make sure you turn it has your home console also, that's it.

NOTE: Rest assured, you won't lose games or saves

Just in order to avoid any misunderstandings: The Original Xbox game 'Rayman 3: Hoodlum Havoc' (released 2003) you mentioned seems not be playable on the Xbox 360. 'Rayman 3 HD' which was released 2012 as an Xbox Live Arcade title however is playable on
the Xbox 360 as well as Xbox One. So which version are you trying to run on your Xbox 360?

Hi!

Rayman 3 HD is compatible with X1. Make sure the console is correctly updated and connected to the Live. Also try to clear the system cache by holding down the power button for 10 secs and try to start the game.
