This page contains a list of frequently asked questions and their answers.


Q: I am having blackscreen issues when playing GTA: Underground. The HUD is visible, but everything else is not, while I can hear in-game audio just fine. What's wrong?
A: This is a known problem and we know it is related to the postfx shader which is used by GTA: Underground. We will fix the issue soon, for now you can use the following workaround step by step:

  1. Navigate to your installation directory and open skygfx1.ini.
  2. Find this configuration option:
    ;colorFilter=PS2 ; Select the color filter
  3. Change it to:
    colorFilter=PS2 ; Select the color filter
  4. Save the file and restart your game. This will override the postfx shader used by GTA: Underground, which means the in-game weather in any additional map included in GTA: Underground will look very weird, but it should solve the issue.

Q: I need help with an installation problem that doesn't appear on this page.
A: Explain your issue in #ug-installation-problems channel on the official GTA Underground Discord server so other members will be able to help you find a solution.

Q: Is the Rockstar Games Launcher version compatible with UG?
A: No. Even downgrading the RGL version will result in many problems afterwards. Either get a downgraded steam version or (the best option) get a 1.0 US version.

Q: I get the following issue when starting up the game: Value of FILE_TYPE_DFF cannot be changed. Editing this limit currently unsupported. Current value: 60000
A: Do not try to edit Fastman's file with the "proper" values, simply use the correct exe. This happens when you don't use the right HOODLUM crack. Try this one instead.

Q: Where can I report bugs which I find during my playthrough?
A: You can report bugs on our bug tracker

Q: My game crashes during the splash screen giving me a runtime error.
A: Download DirectX9 here: https://www.microsoft.com/en-us/download/details.aspx?id=35. It should fix the issue with the CRT exception during the splash screen.

Q: I can’t hear the stories radios for some reason even though the icon is there.
A: Even though the icons are there the actual audio files are not anymore. We made the stories radio as separate download so you will have to download those in order to be able to listen to them.

Q: I crash in UG-MP whenever I die.
A: This is a known bug with downgraded steam versions related to audios. Either get the 1.0 audio files for your Steam version or get the whole 1.0 crack version altogether. We've uploaded a link to the original audio files here.

Q: When I try to launch UG-MP, it gives me an error which says "Unable to locate gta_sa.exe. Please ensure that the launcher is ran from your GTA: Underground installation directory.".
A: As the error suggests, the launcher was not able to locate gta_sa.exe. This might be because you are running ugmp.exe from outside your GTA: Underground installation directory.

Q: When I try to launch UG-MP, it gives me an error which says "Unable to launch. Contact the GTA: Underground development team on our official Discord for further assistance."
A: The launcher failed to run gta_sa.exe. Try running ugmp.exe as administrator. If that doesn't work, please visit our official Discord server.

Q: When I try to launch UG-MP, it gives me an error which says "Unable to open samp.dll. Please verify if GTA: Underground is installed correctly."
A: You most likely touched your installation files, as samp.dll was not found (it must be in the same directory as the UG-MP launcher (ugmp.exe)), and thus UG-MP can not be launched.

Q: Can I play UG-MP on older versions (such as Snapshot 3.3.11)?
A: No, you can't. The game will give an error if you try to do so.

Q: The game crashed, what do I do?
A: If this occurs frequently for you (and you know under which circumstances it happens), open a new entry on our bug tracker. If not, you can join our official Discord server and give us the minidump it generated there.

Q: I get the "Too many people are downloading this file at the moment" error when downloading from Google Drive.
A: Try one of our mirror links.

Q: The game tells me I need a different EXE, and that the one I am using right now is not supported.
A: You will need the 1.0 HOODLUM US crack in order to play GTA: Underground. It can be downloaded here.
