Because Counter-Strike NEO was never planned to be deployed outside the Linux ecosystem, a dedicated emulator is required to run the files.
Currently the game is entirely in Japanese so after running NEO, check out the guide for a detailed walkthrough.
Setup the Emulator
Download the game files (mirror) and extract the contents2.bin (including the .bin contents). You will need an extraction tool such as 7Zip.
For improved resolutions and graphics, download the CSNEO_ResPatcher. This file is optional.
Download the CSNEOLibs_Latest (mirror) archive and extract the contents to the Contents2\csneo2\linux folder.
Go to the TeknoParrot folder (Contents2\csneo2\linux\TeknoParrot) and open the setting.ini file. Change the FREEPLAY value to 1 so you get unlimited credits.
Download the latest TeknoParrot emulator and extract the contents to the same directory the contents2 folder is at. For example, if you extracted Contents2 at C:\Arcade, do the same for TeknoParrot.
Run TeknoParrotUi.exe and install all available updates prompted. After fully updating TeknoParrot, restart it. This might happen a few times if there are further updates. Re-launch TeknoParrot once again and select Counter-Strike NEO from the game list, then click on the ‘Add Game’ button.
Under the ‘Games Added’, select NEO, followed by the ‘Game Settings’ button.
Click on the space below the ‘Game Executable’ and select the hlds_amd file. The file should be located inside the Contents2\csneo2\linux folder. Save the settings, and you will see a success message on generating csneo.xml.
STEP 7 (FOR AMD GPU USERS)
NVIDIA graphics card users can skip this step. If your system is running on an AMD graphics card, a fix is required. Navigate to the TeknoParrot\N2\AMDFixByNezarn folder, copy the cgGL.dll file and paste it at TeknoParrot\N2 to replace the existing one.
Click on ‘Launch Game’ and wait for for the files to load. This usually takes a short while.
Play the Game
Once the game has fully loaded, access the console with the ALT+F7 keys, and enter the following command:
“login 12” (without quotes).
Feel free to change the numbers to whatever you like; 33, 69, 71 and such.
Click on ‘OK’ on the prompt and enter any username. Then click on the [決定] button, followed by the [はい] button and wait for several seconds. The main menu should appear.
For the sake of simplicity, open the console again with the ALT+F7 key and enter the map (e.g. map neo_06collision). For a list of playable maps, click here.
Once the map loads, access the console once again and enter the bot_add command to add bots to the team.
