I'll take wine support for now though. Looking forward to seeing if/how well it will get ran on Steam Deck. The Steam Deck's OS is based on Arch which is a rolling release distro. What this means is it gets the latest updates faster than things like Ubuntu. This may amount to nothing but it will probably help in getting this running well in WINE (Wine Is Not an Emulator).
More importantly, Arch has access to the AUR. This will make installing Launchbox SO MUCH EASIER. Someone will probably make a launchbox-steam-deck that will have it configured pretty perfectly I imagine. One command and it's installed. If the developers see enough demand in that market, then they will happily make a more native implementation, as they have said before. 🙂
