@ExarKunIv Yes I was not able to get the latest version of OpenRCT2 working at all on my 3b+. I was able to get an older version running but it had a glitch with the mouse cursor that I couldnt figure out.

Just wanted to report that I got the latest version of openrct2 built on my rpi 4. Looks like we finally have a more recent version of cmake to work with. Performance using the software renderer with hardware display gets me about 40fps which is great! However I'm still getting the strange mouse/pointer issue. I reported it on GitHub, if that gets fixed I think this would be a great addition to RetroPie ports.

If anyone else who knows a bit more about compiling is able to test out openrct2 I would be interested to hear if they encounter the same issue with the mouse pointer. I watched a couple YouTube videos of people running openrct2 on their raspberry Pi's through a desktop environment and they didn't seem to have issues with the mouse pointer. I have tried running openrct2 through matchbox window manager but I don't know enough to figure out quite how to get it to work. It always tells me it cannot open the display.

So I got a little further with matchbox, I'm having issues though getting it to display the correct resolution and the screen sometimes flickers but the mouse cursor issue is resolved!

Had some issues where matchbox wanted to change res to 4k mode (this is why the game was just a small window). Even though I had my config.txt set to 1080p mode I had to block all 4k modes to get to display correctly. But game is running great now and I just finished my first park!

@quicksilver that is sweet, now i want to get my Pi4. lol

nice park btw

@ExarKunIv if the version of cmake has been updated in raspbian stretch I would think you could get this up and running on a pi 3 too.

ExarKunIv

@quicksilver well that would be cool. not that i would have a clue on how to find out what version of cmake is on the pi3 right now,

quicksilver

@ExarKunIv I'll give it a shot on my pi 3b+ and report back

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.

I wonder if it there are more tycoon games out there that has been ported. I just received Zoo Tycoon Complete Edition for free in my local neighborhood and that game works on Windows 10.

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 ;)

ExarKunIv

@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.
