Pretty much everything to be fair:
- Email with Roundcube
- Chat with Matrix-Synapse + Element
- My files with Nextcloud, easily one of my most used self-hosted apps
- RSS with Miniflux (open to change, as soon as I find any RSS backend with a usable Android app)
- My social network presence, with Pleroma (again, subject to change, as soon as I know how to properly move my domain to a different software tool)
- My media, with Jellyfin
- Peertube to watch videos from other instances and comment on them
- And finally, all of the above protected with a password vault from Vaultwarden
EDIT: For those wondering, I use @yunohost@mastodon.social ( https://yunohost.org ) as my server manager
That, or a *decent* upscaling algorithm such as xBRZ. Old upscalers like Super 2x SAI made pixel art look like a cheap watercolor, and made later upscalers get a bad fame. Nowadays a good upscaler basically turns the game screen into a vectorized set of lines, and it looks much better, closer to what the pixel artists intended the end result to look like on a big screen.
