Recently someone implemented Rollback Netcode for Super Smash Brothers Melee using a modified version of the Dolphin Emulator. This can be found on the site slippi.gg.
Because of this, Smash Bros. fans finally get the thing they have always wanted. A good online system.
The Melee community would really appreciate a video showcasing options for a "Portable Netplay Machine".
This would need a 120Hz screen, a dedicated GPU that supports the settings mentioned on the site, at least 1 USB Type A port for a GameCube controller adapter, and optionally an Ethernet port. The Ethernet port is optional since adapters can be used for that one I guess, and for a portable station I would assume WiFi is being used most of the times.
This could even potentially be a mini build with bare minimum specs and a small external monitor.
It's worth pointing out the Melee community is used to playing on small CRT TVs, so screen size isn't too important. While a large screen is nice, a 13in laptop screen works in this case.
I think this would be a great opportunity to talk about netcode (maybe a separate video on a separate channel), and point out machines for a niche community.
