Linux for iPod?

I found my 7th gen iPod Touch running 15.8.2. This device is no longer supported by Apple so I can’t Sign in with Apple ID to do anything useful. Any ideas of how I can save this device from becoming e-waste? I was trying to add Delta emulator to use it for roms but no luck.

Any ideas/suggestions?? 🤷🏼‍♀️ TYIA 💜
