Is there any way to automate downloading ROMs for retro games, similar to Sonarr/Radarr?

I had been using,

1. Google Drive - 1600 INR per year
2. 1Password - 4500 INR per year
3. Netflix - 2400 INR per year
4. Prime Video - 1500 INR per year
5. VPS - 7000 INR per year

That is 17000 INR or $180 per year.
Last year I bought a mini PC for 20000 INR or $210 and now I self host,

1. Immich
2. Owncloud
3. Vaultwarden
4. *arr Stack

which saves me that $180 every year right now and gives me more control and privacy.

But now I can also self host many more things which I didn't used earlier because I had to pay a subscription.
