Classic, everything is working now.
Works out of the box with the latest proton, doesn't ask for the CD key or anything

please insert your rollercoaster tycoon loopy landscapes pack cd in the following drive
It asks me to insert a disc and errors out. The various ideas on this forum don't appear to help sadly.

Some edits to wine registries may be needed. Worked fine on my desktop and steam deck, but not my laptop.
If you end up with the "Please Insert CD Key" error, verify/add the following registry key to the system.reg file: [Software\Wow6432Node\Fish Technology Group\RollerCoaster Tycoon Setup] 1689209680 #time=1d9b5249af44f4e "addon"=dword:00000001 "CancelPrompt"="Cancel" "CDKey"=dword:00000000 "CharSet"=dword:00000000 "executable"="rct.exe" "FontFaceName"="MS Sans Serif" "FontPointSize"=dword:0000000c "language"=dword:00000000 "OKPrompt"="OK" "path"="E:\steamapps\common\RollerCoaster Tycoon Deluxe" "SetupPath"="E:\steamapps\common\RollerCoaster Tycoon Deluxe\RCTdeluxe_install" "title"="Roll" Also, make a link to the parent directory of your steamapps directory (e.g. /home/need_an_adult/Game) in the dosdevices directory called "e:" (no quotes). I assume you can use different paths and it would still work just fine, just make sure wine can access the "RollerCoaster Tycoon Deluxe" directory, and the "RCTdeluxe_install" directory (that's how it 'reads' the disc).

Alt-Tabbing away from the game causes the game window to continually flicker on screen
Areas such as the save menu where the game opens Windows' native UI can cause issues with selecting stuff, but I managed to save and load a game successfully
its a fun classic, but i STRONGLY recommend downloading OpenRCT2 or buying RollerCoaster Tycoon Classic instead
changed executable, ran the game in window mode
i made the config
fullscreen displays the original 4:3 resolutions on the top left side of the screen, window mode fills up the screen with a 4:3 aspect ratio, made a fix to stretch window and fill the whole screen
the version of proton steam uses by default has some sort of issue and does not allow you to save games, GE-Proton7-38 does allow you to save games properly
if you for some reason want to play the vanilla version, set the game to window mode, you will get a 4:3 resolution but atleast the game will fill up the screen vertically, if you want a widescreen option, you can try downloading this mod
https://www.moddb.com/games/rollercoaster-tycoon/downloads/rctdeluxe-fix-for-steamdeck
tough honestly, you are probably better off downloading OpenRCT2 and running this game through that or buying RollerCoaster Tycoon Classic, but if for some reason you only have RCTD, dont want to buy Classic and dont want to download OpenRCT2, then just download the fix
Works without problems. But you have to care for the path of your steam library.
The path to your steam library is not allowed to contain a . (dot). Unfonrtunately this is the default if you did not changed your library path. The default on a steam deck is /home/deck/.local/share/Steam/steamapps/common/RollerCoaster Tycoon Deluxe/ If you add another folder as library e.g. /home/deck/SteamLibrary and move the game installation to it. After that saving and loading works as expected.
The game installs, but cannot be opened. It gives a message asking for a CD key.
If the save/load functionality doesn't work then it can't really be played on your map on multiple occasions
Even if not full screen after a change in the game, it was on the left side rather then centered
No sure if couldn't load or save

If you don't care about your battery life, this game works well. Specify a virtual resolution before playing to fix fullscreen.
Text is harder to read at higher resolutions as the game does not upscale.
You must specify a virtual resolution in the game's properties in Steam, then set the game's internal resolution to match the virtual display.
Huge power draw on Steam Deck.
I do not recommend this title on Steam Deck at this moment due to battery drain. Please note that I did not try this with OpenRCT2, which may or may not change battery impact.
Fully playable on Steam Deck. Minor resolution issue must be adjusted using game options once. Set Left Joystick to arrow keys for movement.
- Left Joystick = Direction Pad with arrow keys. Used to move the in-game viewpoint.
- Right Joystick = Joystick Mouse, with mouse sensitivity set to 25. Used for fine adjustments of the mouse, or casual play without the trackpad.
- All other controls are accessible via the in-game menu, and hotkeys can be assigned according to individual preference. Hot key commands are visible through the in-game "Options" menu.
Upon first booting the game, it will be displayed in a small window in the upper-left of the Steam Deck, not filling the height of the screen. Using the trackpad mouse controls:
- Start any game mode.
- Select the floppy disc icon from the on-screen menu.
- Select "Options"
- Change the "Display Mode" to "Window"
The screen will now fill the Steam Deck resolution and no further adjustments will be necessary.

When running RollerCoaster Tycoon Deluxe after a fresh install, I was getting the "Please insert your RollerCoaster Tycoon Loopy Landscapes Pack CD in the following drive" and "Missing or inaccessible data file" pop-ups for several versions of Proton. For the solution to this problem, see the summary section of this post.
As others have noted, playing the game in Fullscreen can be a little buggy when switching to other windows. If I go to another window while RollerCoaster Tycoon is fullscreen, RollerCoaster Tycoon will start flashing uncontrollably. On my desktop environment, the only way of regaining control of the program is alt-tabbing in. This may have to do with my desktop environment and its settings, and it may be possible to fix this via winecfg; I have not tried.
The other major bug with windowing is that the "Save Game" and "Rename Ride" windows cannot be interacted with unless you drag them outside of RollerCoaster Tycoon fullscreen window. If you do this, you will get the flashing I described. However, it is possible to drag the windows outside the fullscreen, use the windows, then alt tab back into the game. This is doable but a little annoying.
Playing windowed gives me no windowing issues, but the graphics are a bit small for my eyes.
Summary: When running RollerCoaster Tycoon Deluxe after a fresh install, I was getting the "Please insert your RollerCoaster Tycoon Loopy Landscapes Pack CD in the following drive" and "Missing or inaccessible data file" pop-ups for several versions of Proton. I discovered that for some reason, the wine instance RollerCoaster tycoon is running in requires the RollerCoaster Tycoon game disk to be mounted, and for certain game files to be copied to Program Files (x86)
. Doing this is simple:
- Find the
steamapps
path including most of your Steam files. Since I'm on Debian, this path was~/.steam/debian-installation/steamapps
for me. - Run the following script, which creates symlinks in the game's wine prefix to allow the game to launch. Change the
export STEAM=
path on the first line to the path for your computer:
export STEAM=~/.steam/debian-installation/steamapps
# Make drive I: in the game's wine prefix contain RollerCoaster Tycoon install files, as if the RollerCoaster Tycoon game disk is mounted to drive I:
ln -s "$STEAM/common/RollerCoaster Tycoon Deluxe/RCTdeluxe_install" "$STEAM/compatdata/285310/pfx/dosdevices/i:"
# Make a directory in the location where RollerCoaster Tycoon expects the game to be installed in the wine prefix's C drive, then add a symlink to the game in that directory
mkdir -p "$STEAM/compatdata/285310/pfx/drive_c/Program Files (x86)/Infogrames Interactive"
ln -s "$STEAM/common/RollerCoaster Tycoon Deluxe" "$STEAM/compatdata/285310/pfx/drive_c/Program Files (x86)/Infogrames Interactive/RollerCoaster Tycoon Deluxe"
- You can now launch the game on Steam. This may not be the only way to fix this issue, so if anyone knows a simpler way please post it.
Game is perfectly playable. Either run the game in Desktop Mode, or set the game in Windowed and scale it during Gaming Mode.
Once in-game, click on the Floppy Diskette icon to go to the settings and change the screen resolution from Fullscreen to Windowed, and let Steam scale it using Linear, Nearest, Integer or FSR (personal recommendation: FSR). This will center the game screen for proper use.
Quick Access Menu battery performance settings:
- Refresh Rate set to 40: in-game FPS is 38 so reducing the screen refresh rate is beneficial.
- Thermal Power (TDP) Limit enabled, set to 3 Watts: game does not use much power on its own.
- Manual GPU Clock Control enabled, set to GPU Clock Frequency 200: game does not use much power on its own.
Fullscreen issues:
- Games start with
Full Screen 640x480
option, causing the game to be too small and appearing in the left top corner.- To fix this, go to the tutorial (third option on the title screen, clicking on the trackpad required once you load in to get control over the cursor) or try a new Scenario. Then click on the Floppy Diskette icon, then on the Options button. Change the Display Mode from
Full Screen 640x480
toWindowed
for a centered game screen. Filtering (Linear, Nearest, Integer, FSR) can be adjusted in the Quick Access Menu.

Personal recommendation in Scaling Filter choice: FSR seems the prettiest over Linear (blurry), Nearest (uneven pixels all over) and Integer (too small).
Doesn't support 800p natively, only 768p at max. Lower resolutions don't scale to the screen of the Steam Deck, unless you are in windowed mode.
Game runs natively at 38 fps. This game is fully playable on Steam Deck, but would recommend OpenRCT2.

Game asked for data CD when executed, but it's impossible to provide it one.
Can't get to the actual game.

Doesn't work on Fedora 36
For any version other than 5.13-6 it prompts for a CD. For Version 5.13-6 it does not prompt, but also doesn't display the menu. Tried Xorg, Wayland, Intel, Nvidia, doesn't matter. Won't run.
Save/Load Dialog is finicky--need to offset mouse and/or use keyboard shortcuts to use it correctly
Renaming dialog very hard to work with, flickers a lot

The gameplay is great and functions just like it would on Windows, but the dialogs for renaming and saving are buggy although functioning
The dialogs for renaming buildings and for saving/loading the game appear behind of the fullscreen window, so you need to switch to them with alt+tab.
Gives a pop-up to insert CD. Switching off Steam overlay seems to not alleviate this issue.
turn off steam overlay

Loading progress bar halts and asks for Loopy Landscapes Pack CD
I used steam's "Verify integrity of game files" option and it detected no issue. For whatever reason, it seems that the program does not have access to the files it needs in order to run, despite a "fine" install. I forced older Proton version after seeing others use this specific version successfully with this game.

Runs but can't save or rename rides
Game will run out of the box if you turn off “Steam overlay while in-game”.
- Go to game.
- Click “gear” icon
- Click on “Properties”
- Click on “General”
- Here you will find “Steam overlay while in-game” - Untick this box.

Game will run out of box!

Works fine out of the box. No issues with anything. Great experience
In "windowed mode" everything is very small. Using fullscreen (4:3 resolution) it was much more fun


Works perfectly out of the box, just don't have a second monitor
- In a multi-monitor setup, the mouse pointer will sometimes be locked into the monitor that the game is not running on. I'm still able to interact with the game via the mouse, but I can't see where the pointer is.
- Sometimes in a multi-monitor setup, the game will split between the two monitors, but the mouse pointer will be locked to one monitor
Runs like native

Runs pretty much as expected.
When first booted, save selector doesn't register mouse. Fixable by alt-tabbing out then clicking the window in the system tray. Trying to alt-tab back in crashes the game. Also crashed when I tried to pull up the Steam overlay, but I only tried that once.
Was able to beat the first three scenarios. Pretty impressive, considering the original was written in Assembly.
Game runs perfect, with some minor picky details
Switching resolutions can crash the game
Just a slight noticeable delay with my mouse position and what the game had shown as selected. Nothing game breaking, just take your time.
Save games cannot be saved in default location. They'll pretend to, but you'll find they're gone when you try to load. I just made a folder in my user directory and it worked just fine.
Sometimes you'll get the infamous video driver violation at the very start when trying to skip the intros. Just gotta be patient and the game will load fine.

Game Runs Great. Save files don't work properly.
Can not save in the default location.

Runs perfectly. No glitches.


Seems to run flawlessly, but only initially; after about 30min to 1hr of playtime, the game starts to slow to a crawl. HOWEVER, this only happens if the cursor is hovering above the window, as soon as you remove the cursor from the game window, the game resumes normal speed.
Closing and opening the game temporarily alleviates the issue, and park size has no impact.
Tried different Proton versions, no fix.


Platinum for working better than in windows. Not even my saves needed any kind of management.

Works out of the box.


Works beautifully - actually less problematic than when I installed and played this on Windows. Platinum, for sure.


Working perfectly out of the box.

Ran out of the box no tweaks required, some minor weirdness with savegames, but picking a specific path (rather than saving to the default location) for those avoids them.

Runs perfectly fine aside from the fact that the save and load dialogues can't be navigated by a mouse and a keyboard is needed.

Works perfectly!

Runs perfectly.
