Frequently Asked Questions

How do I use this installer?

  1. Get the installer from the Download page.
  2. Save sadx_setup.exe (or extract the archive if you got the offline version) to your desktop – or anywhere else really, just make sure you have enough drive space.
  3. Run sadx_setup.exe
  4. Follow the instructions in the installer.

The installer is only meant to be used the first time you install mods. As such, you only need to use it if you have just (re)installed SADX. If you have already used the installer on your copy of the game, you don’t need to download new versions of it or run it again. To update your mods, check for updates in the SADX Mod Manager instead.

Is SADX Mod Installer the same thing as SADX Mod Loader? What is SADX Mod Manager? What is SADX Launcher?

SADX Mod Loader is a tool made by MainMemory that makes it possible to mod SADX.
SADX Mod Manager is a program to manage your mods. It comes with the Mod Loader. A new Mod Manager called SA Mod Manager was released in 2023.
SADX Mod Installer (this tool) installs the Mod Loader and a selection of mods.
SADX Launcher is a configuration tool. It replaces the Steam version’s configuration tool when you install mods using the Mod Installer.

Can I get mods on the Steam version of SADX?

The only way to get mods on the Steam version is to convert it to the 2004 version. This installer can do that.

I have a Steam version of SADX.
I have an old disc version of SADX PC.
I have a European/American/Japanese version of SADX PC.
I have a newer re-release of SADX PC that I got on Amazon/eBay.
Can I use this installer?

The installer works with the following versions of the game:
– Steam/Dreamcast Collection Remastered (2016)
– US (2004)
– EU (2004)
– Best Buy (2004)
– Korean release (2004) – the game will be converted to the US version, and Korean language assets will be removed
– Sonic PC Collection (2009)

It doesn’t work with the following versions:
– Original Japanese release (2003)
– Sold Out Software release (2006)
– Dreamcast Collection (original 2010 release)
– Any cracked or modified versions

Can I get mods on the Dreamcast/Gamecube/PS3/Xbox360 version of the game using this installer?

No, this installer and the Mod Loader can only be used with the PC version.

My antivirus program detects the installer as a virus. Is it a virus?

No, it isn’t a virus. The installer downloads files from the Internet and runs them, so it causes false positives with antivirus programs.

I get an error when the installer is trying to convert the Steam version to the 2004 version. What should I do?

  • Make sure no files in the game’s folder are currently open and the game isn’t running.
  • Add an exception for sadx_setup.exe in your antivirus program (or disable it before running the installer) and try again.

Every time I try to install or enable the Mod Loader, it shows an error mentioning SADXModLoader.dll or CHRMODELS.dll. What should I do?

Add an exception for the installer (sadx_setup.exe) and the Mod Manager (SADXModManager.exe or SAModManager.exe) in your antivirus program and try again.

I’ve used the installer on the Steam version of SADX. The game runs but there is no music or voices. What should I do?

It’s possible that the installer has failed to convert your Steam version of SADX to the 2004 version, or your SADX installation is missing files. Reinstall the game from Steam and run the installer again.
Alternatively you could install the ADX Audio mod to get ADX voices and music. It’s still better to reinstall the game and run the installer again because some sound effects may also be missing.

The game works but the videos won’t play. What’s wrong?

SADX relies on Windows Media Player to play videos and it doesn’t like certain video codecs.
1. If you use a version of Windows that doesn’t include Windows Media Player, install it separately.
2. If you use Smooth Video Project (SVP) or LAV, disable or uninstall them before playing. Some other codecs like ffdshow may also cause issues.

Does this installer work with BetterSADX? Is it the same as BetterSADX?

I made this installer as an alternative to BetterSADX. You can use this installer if you have used BetterSADX in the past.
