HTPC Steam & Emulators

Bazzite HTPC at 192.168.1.86. See htpc-bazzite-proton for Proton game compatibility details.

Hardware

CPU: Intel Core i7-6800K, RAM: 32 GB, GPU: AMD Radeon RX 570
TV: LG webOS at 192.168.1.75 (HDMI)
OS: Bazzite 44 (Fedora-based, immutable OSTree, bazzite-deck variant)

Gamepads — 8BitDo Ultimate (2 dongles)

Critical: both 8BitDo Ultimate dongles (2dc8:3106) must be on separate physical USB ports, not sharing a USB hub. If both share the Huasheng USB2.0 HUB on port 006, the second dongle fails to enumerate (#Ifs=0 Cfg#=0) and creates no /dev/input/js.

Working USB layout:

Port 005 (direct xHCI, no hub) → 8BitDo #1 (E417D8D87F0C)
Port 006 → Hub Port 001 → 8BitDo #2 (E417D8C197E4)
Port 006 → Hub Port 004 → Xbox 360 Wireless Receiver

Symptoms of wrong layout: lsusb shows both but second has #Ifs=0; only one /dev/input/js; Steam sees one controller.

Rules

Game save paths: managed per-emulator; see emulator config in Bazzite
Gamepad config: stored in Steam controller profiles, backed up to ~/controller-profiles/
Steam shortcuts for non-Steam Windows games: use Proton Experimental

ROM Symlinks (Data partition → EmuDeck)

Emulators expect ROMs at ~/Emulation/roms/<system>/. Symlinks from the Data partition (/run/media/bazzite/Data/):

ln -s "/run/media/bazzite/Data/n64 roms"     ~/Emulation/roms/n64
ln -s "/run/media/bazzite/Data/snes roms"    ~/Emulation/roms/snes
ln -s "/run/media/bazzite/Data/gba roms"     ~/Emulation/roms/gba
ln -s "/run/media/bazzite/Data/3ds roms"     ~/Emulation/roms/3ds
ln -s "/run/media/bazzite/Data/ps2 roms"     ~/Emulation/roms/ps2
ln -s "/run/media/bazzite/Data/dolphin roms" ~/Emulation/roms/wii
ln -s "/run/media/bazzite/Data/cemu roms"    ~/Emulation/roms/wiiu
ln -s "/run/media/bazzite/Data/mame roms"    ~/Emulation/roms/mame
ln -s "/run/media/bazzite/Data/sega roms"    ~/Emulation/roms/genesis
ln -s "/run/media/bazzite/Data/nes"          ~/Emulation/roms/nes

After symlinking, run Steam ROM Manager (EmuDeck) from Desktop Mode to import ROMs into Steam with cover art.

Non-Steam Windows Games

/run/media/bazzite/Data/games/ — 38 pre-installed games (Bayonetta, Cuphead, GTA V, Witcher 3, etc.). Add as Non-Steam games with Proton Experimental.
