About
Resident Evil 3: Nemesis is the third main installment in Capcom's survival horror series, following Jill Valentine's escape from a zombie-overrun Raccoon City as she is relentlessly hunted by the bio-weapon Nemesis. Built on the same engine as its predecessors, it uses 3D character models over pre-rendered backgrounds with fixed camera angles. Originally a PlayStation hit in 1999, it was later ported to Windows and received critical acclaim. This recipe targets the classic 1999 PC release enhanced by the community Seamless HD Project mod, built on Gemini's Classic REbirth.

⚙ Setup notes
Mod: The Seamless HD Project — a community full-game mod that overhauls the 1999 PC Resident Evil 3 with HD pre-rendered backgrounds and seamless room transitions, built on Gemini's Classic REbirth.
Base game: Needs the base game (the classic RE bundle is sold on GOG — supply your own copy). Confirmed working on Steam Deck by multiple users.
Install: Install the base 1999 RE3 (SourceNext/GOG) via Heroic, apply Classic REbirth then the Seamless HD Project, and force a Proton with DXVK 2.5.3 — GE-Proton 9.25 or Proton 9.0 (Beta).
Patch on Windows first: The Seamless HD Project patcher relies on Windows APIs and will NOT run under Linux/SteamOS. Run the patcher on a Windows PC, then copy the fully-patched game folder onto the Deck. Launch the patched bio3.exe (rename to 4249120_Launcher.exe if you want Steam playtime/overlay; some packagings use a custom R.P.D. Terminal launcher for the same purpose).
Proton: DXVK MUST be enabled or the HD mod silently won't render. Use the ddraw,dinput8 DLL override above (WINEDLLOVERRIDES="ddraw,dinput8=n,b" %command%).
Display: In Classic REbirth Settings > Advanced, DISABLE 'Force 240p Backgrounds' so the HD backgrounds show on Deck.
Controller: Classic REbirth swaps the old DirectInput 5 input for XInput / DirectInput 8 / Raw Input, so the Deck gamepad is recognised for tank or alternate controls. A Steam Input gamepad layout is still the most reliable on Deck; the optional Modern Controls Plus add-on gives RE1-Remake-style analog movement for those who dislike tank controls.
The one thing to know
ProtonDB: The classic 1999 RE3 (SourceNext/GOG) is not a Steam title, so there is no ProtonDB entry — protondb_tier left empty. Community reports (GBAtemp / GOG forums) say plain Classic REbirth runs well on Deck, while the Seamless HD layer is the fragile part.
Supply your own copy: The Seamless HD Project is a free community mod that needs the base game — bring your own legally-owned copy (GOG sells the classic 90s PC bundle).
Finicky HD mod: Confirmed working on Steam Deck, but the HD mod is finicky: it needs DXVK 2.5.3 (GE-Proton 9.25 / Proton 9.0 Beta) AND 'Force 240p Backgrounds' disabled in Classic REbirth's Advanced settings, or you get graphical glitches / no HD backgrounds.
Stability: Plain Classic REbirth alone is rock-solid; the HD layer is the only fragile part.
Controller: Controller works (Classic REbirth modern controls + Steam Input).

Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options, Proton version)
and registers the shortcut with artwork.
