Awesome that you finally got it working. It must be because of the higher cmake version that the port requires. I can see this potentially becoming one of RetroPie's official source ports in future versions.

That would be really neat. Im new to all of this stuff and still learning so I'm not sure how to get it to run through runcommand or create a build script. Do you have any resources that you used to learn how to do that? You are kinda like the king of source ports around here. :) Also if at some point you decide to try to add openrct2 to RetroPie I would be glad to assist in anyway I can.

@ExarKunIv cmake in raspbian stretch repository is still stuck on version 3.7. I'm sure there is a way to build cmake from source but I don't think I'm going to mess with that right now. I would just get a pi 4 if I were you ;)

@quicksilver yea i was kinda thinking that, maybe for my birthday i get me a gift for my self. :)

@quicksilver To manually create a runcommand launch file there are some setup that you need to do first. You will need to create a config folder and a emulators.cfg file for the port and point it to the binary that you created/built with cmake in the source directory that you used. Then create the runcommand launch file openrtc2.sh and point to the config folder.

An example would be

Create a config folder for the port named openrtc2 ex: /opt/retropie/configs/ports/openrtc2
Inside the config folder, create a emulators.cfg and edit the file with typing the correct path to the the openrtc2 binary in your source directory.
Create a runcommand launch file inside "/home/pi/RetroPie/roms/ports/"name it openrtc2 and edit the file with typing the correct path to the config folder.

The emulators.cfg file will look something like this:

openrtc2 = "/home/pi/Downloads/openrtc2/openrtc2"
default = "openrtc2"

The runcommand launch file will look something like this:

#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 _PORT_ "openrtc2"

If this doesn't work, you could also try by just only creating the runcommand launch file and make it look like this.

#!/bin/bash
cd /home/pi/Downloads/openrtc2
./openrtc2

It is quite possible to get it working on a Raspberry PI 3B/3B+ but it will require one to update the cmake version. I know it can be done since I once did it on my Raspberry Pi 3B. Unfortunately I don't remember precisely how I did it. I think I manually compiled the newer cmake version and then it worked with compiling the source port that i tried at the moment.

Same here, I did have it running on my pi3 at one point but I don't remember the steps I took to get there. Thanks for all the great info, I'll look into this for sure. Learning this stuff is a ton of fun.

Great work I can't wait to play this. If only I had the slightest clue how to do what you've done.. I'd be on it by now 😂

If you ever feel the need to make an idiots guide and want an idiot to test it... Let me know 👍😂

quicksilver

@Jste84 I'll see about posting a step by step list of how to manually compile it for a pi 4. I'm not 100% sure that I'm doing everything correctly (even though it seems to be working) so it may be good to post if for some peer review as well.

Jste84

@quicksilver if you do that I'll happily test

tpo1990

@quicksilver That is exactly my experience as well just with a different game/source port that I got running earlier on my Pi 3B. Even though it takes time to learn it all, once you have managed to get a better knowledge of understanding how Linux works with compiling and installing you will get the success of it and just feel great for what you have accomplished. ;-)

Just keep on the good work and eventually you will get there. :-)

Your welcome. I will gladly help you out as much as I can. Just let me know.

So here are the build instructions for anyone who is interested. This will get OpenRCT2 up and running on your pi 4 (im sure the game can be run on pi 3 as well but you'll need to manually compile a newer version of cmake). The game can be run without a window manager but performance is not as good and there is an issue with the mouse cursor. I will add instructions on how to run through matchbox-window-manager but I will need some peer review with that part because I dont think I have it working 100% correctly.

First step is to install needed dependencies:

sudo apt-get install --no-install-recommends -y cmake libsdl2-dev libicu-dev \
    gcc pkg-config libjansson-dev libspeex-dev libspeexdsp-dev libcurl4-openssl-dev \
    libcrypto++-dev libfontconfig1-dev libfreetype6-dev libpng-dev libssl-dev libzip-dev \
    build-essential make

Next we need to get the source from the repository (change master to develop if you want bleeding edge version):

git clone -b master --depth 1 --recursive https://github.com/OpenRCT2/OpenRCT2.git

Next, we need to compile (this may take a while):

cd OpenRCT2
mkdir build && cd build
cmake ../ -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS="-Ofast -DNDEBUG -mcpu=cortex-a72"
make -j4

Now run make install this will download required resources (json objects, title sequences) and installs openrct2 under /usr/local by default:

make install

OpenRCT2 requires original game files to run, I installed RCT1 (optional) and RCT2 on my windows computer then copied the install directories to /home/pi/RetroPie/roms/ports/. Im not sure if there is a better way of doing it or if a different location for the files should be used but this method does work. On first boot of OpenRCT2 it will ask for the location of the game files, or you can input the location manually by editing the config.ini located at /home/pi/.config/OpenRCT2/

To start the game run ./openrct2 from the build directory.

This section I need help on
Running the game without the window manager performance will not be as good and the mouse cursor has issues. So what I did was install matchbox window manager, xorg, and x11-xserver-utils:

sudo apt-get install xorg matchbox-window-manager x11-xserver-utils

Then I run the game using this command:

xset -dpms s off s noblank matchbox-window-manager & startx /home/pi/OpenRCT2/build/openrct2

However I get an error saying that xset cannot open the display, but the game still boots (im assuming because of the startx command?) I had issues with the game automatically running in 4k mode so I had to force 4k mode off in my /boot/config.txt/ I also noticed that when running the game this way that you cannot scroll the screen by moving your mouse to the edge of the screen, to work around this you can right click-hold and drag to move the screen around. Im hoping this is an issue because of something Im doing incorrectly (which I am sure I am). So if anyone who knows how all of this x server stuff works I would appreciate some pointers on getting this part to work right.

Some pointers for performance: Once the game is up and running I lowered the display res via the ingame options to 720p and increased the window scale to 1.5. I also used "software (hardware display)" as the drawing engine because everything looks a bit clearer/sharper. Uncapping the framerate also makes for a smoother gameplay experience because the default FPS is capped at 40. Also make sure that the games config.ini has proper permissions otherwise changing settings in game wont persist between game sessions.

Trying this now, but unfortunately I'm getting an error at step 2.

Fatal: repository '1' does not exist 😔

Hoping you can help @quicksilver 👍

quicksilver

@Jste84 sorry about that, there was a syntax error in the command I posted. I fixed it, can you try again?

Jste84

@quicksilver yip will try it again now 👍

Jste84

@quicksilver past step 2... Will let you know how I get on with the build. . Thanks for the guide and help.

This will make my day if it works

Jste84

@quicksilver I'm getting another error... In step 4, it says 100 per cent but I'm getting the following message after.

CMake Error at cmake_install.cmake:48 (file) :
file DOWNLOAD error: cannot create directory
'/usr/local/share/openrct2/title' - Specify file by full path name and verify that you have directory creation and write privileges.

Could this be because I've set up the pi4 to use my cloud home as storage. I had problems with save states earlier...

Not sure what to do to fix this. If I use winscp to manually add the directory would that work?

Edit: gone into winscp and can see there is no directory for openrct2 in usr/local/share.

Also moved the directories, done a reset but not seeing anything in ports...

Last thought... I've used the gog versions of the games which are RCT deluxe and rct2 triple pack... Assuming this won't make a difference?

quicksilver

@Jste84 try running this from the build directory within the openrct2 directory:

DESTDIR=. make install

Jste84

@quicksilver seem to have got by this now..

But nothing is showing when I go to ports..

Although I'm not sure if that's how I'm meant to open the game?

quicksilver

@Jste84 yes this isn't a build script for RetroPie so it won't appear in ports. You'll need to run it from the command line using the commands I posted above. You can also take those commands and put them in a shell script that can be run from emulationstation. Once we have a proper build script set up then it will appear nicely in ES and go through runcommand.

Ok... So this will be my silliest question yet @quicksilver ...

So the last step says run openrct2 from the build directory... How do I do that?
