    Hi Memorix101,

    Awesome work.

    I have five problems:

    - Windowed mode looks perfect, but in Fullscreen, the game renders at 16:9 aspect ratio but into a 800x600 resolution. So everything looks narrow. The interesting thing is that this happens when desktop resolution is 16:9 (for example 1080p). If desktop resolution is 4:3, then fullscreen has correct FOV. This means your port can run the game at 16:9 aspect ration, but being limited to 800x600 makes it broken.

    Examples of how the game renders FOV depending of desktop resolution aspect ratio and using fullscreen 



    - Arrows that represent cars in the map, are inverted. 

    - Car doesn't react correctly driving under water. In the original game, the car floats and is hard to control.

    - I found no way to save/load the profile

    - I found no way to remap the controls. Handbrake in controller X button is a no way for me :P

    Oh! Thank you for the hint! I never tested the game in fullscreen. 😅
    The reimplementation is incomplete, so it misses some features or others are just hard coded. 
    The project is open source on GitHub so in case you are interest you can contribute to the project. 

    when i try to run the app on mac it just doesn't open (i'm on mac 10.15)

    You need to install  XQuartz. Otherwise, it will not launch.

    i did that and it still doesn't launch

    The app is a wine bottle wrapped as a macOS app. You can open it like a folder with a right-click and inside it is a Wine configuration tool. Launch it, maybe something needs to be adjusted to your macOS version. I am still running 10.14 Mojave as I need 32bit support for some apps I am using.

    i spent a little time fiddling about with the wine wrapper thing and it still didn't work no matter what i did,  i think it might be my macos version causing the problem, sorry for wasting your time :/

    No problem at all. Maybe we can fix this at a later point :)

    I can't play the full version, I run the game and I was told to set up a demo

    Please read the installation instruction above!

    Is it possible in any way to run Carmageddon 2 through openc1?

    Edit: forgot to add "2"...

    Sadly, no. Because Carmageddon 2 is using a different engine and OpenC1 only reimplements the engine for the first Carmageddon.

    Really? I thought I read somewhere that it used the same engine that's why I asked. 

    It's a shame, Carmageddon 2 could use something like this as well haha 

    BTW, openc1 works on Linux? 

    Yes, but not native. You need to install Wine to do this.
    It's how the macOS version works. It's just a Wine wrapper for Mac.

    hey, there still seems to be some error on startup, i can get in menu, but the game crashed when i try to change car, or start a race

    On my end everything is working fine :( I need more details ... what platform are you playing? I'm on Windows 10. Please make sure that all dependencies are installed as listed on the download page.

    Hello! I clicked on the .exe (I guess) and nothing happens, doesn't open any game, why?

    Hey, I verified the download and found out it was somehow missing files. I updated it. I should work for you now. :)
