About
Zoo Tycoon (2001) is a construction and management simulation by Blue Fang Games / Microsoft in which players design, build and run their own zoo. It is long unavailable from Microsoft — never released digitally — but runs cleanly on Steam Deck via Proton Experimental with very low power draw. The Marine Mania and Dinosaur Digs expansions also work via the same method.

⚙ Setup notes
Game: Zoo Tycoon (2001, Blue Fang Games / Microsoft) — classic zoo-building simulation. Never given a digital release; long unavailable from Microsoft. Supply your own disc or installed copy.
Install: Install your copy under a Wine/Proton prefix, then add zoo.exe as a non-Steam game in Desktop Mode. SteamDeckHQ ran it on Wine-GE 8-26; Proton Experimental also works. The exe ends up at e.g. drive_c/Program Files/Microsoft Games/Zoo Tycoon/zoo.exe.
Resolution fix (recommended): By default it runs 4:3 with black bars. Edit zoo.ini in the game folder and, under the [user] section, set screenwidth=1280 and screenheight=800 for a proper Deck aspect ratio.
Performance: Hard-capped to 60 FPS — apply a 60 FPS frame limit and a ~4W TDP cap. Real-world power draw is roughly 8–9W, giving about 6 hours on an OLED and ~4 hours on an LCD. Mouse-driven UI works well with the Deck's trackpad or in desktop mode.
Do not toggle windowed/fullscreen: switching modes in-game crashes it and offers no benefit.
Expansions: Marine Mania and Dinosaur Digs expansion content also work via the same method.
SteamDeckHQ: Featured in *Classics on Deck* #3 (March 2025).
The one thing to know
Supply your own copy: Never released digitally — supply your own disc/installed copy. Add zoo.exe as a non-Steam game.
No digital storefront: long unavailable from Microsoft with no current legal purchase path (a GOG dream-list page exists but it is not for sale).
Disc DRM (SafeDisc): retail discs use SafeDisc, which is broken on Windows 10/11; under Wine/Proton this is generally a non-issue, but be aware of it if installing from disc.
Resolution: Defaults to 4:3 with black bars. Edit zoo.ini [user] section: screenwidth=1280, screenheight=800.
Capped at 60 FPS / ~8–9W: apply a 60 FPS limit and ~4W TDP cap. Do not toggle windowed/fullscreen in-game — it crashes.
Expansions: Marine Mania and Dinosaur Digs expansion content work via the same method.

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.
