# 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
|
|
|
|
## Save Locations (approximate)
