  • It may be a good idea to add a clear disclaimer, for those who can't seem to understand the meaning of "2004 version ≠ Steam version".

    Kinda like this - Disclaimer: This Mod loader is for the physical 2-disc version published by Activision in 2004 for Windows 98SE/ME/NT/2000/XP. This program was made for the US version only. If you are playing a Japanese or European copy, or the Steam version, this tool will not work with those versions! PkR's SADX Mod Installer will replace the executable with the US version if the existing executable is incompatible.

    The tool to convert the Steam version to the 2004 version can be downloaded [here]. This tool will also install all necessary files and dependencies, as well as several options that fit your preferences.

    When trying to download SADX Mod Manager, when I try opening it, it asks for updates in which my Antivirus picks up an Infected Source; "mm.reimuhakurei.net/sadxmods/SADXModLoader.7z", meaning it can't install updates.

    Just recently reinstalled with better sadx 4.4.4 , but whenever I start up the mod loader I keep getting "The specified module could not be found" for four mods. Not major, but how do I fix this? Four mods are Idle Chatter, Smooth Camera, Egg Carrier Ocean music, and steam achievements.

    I've got a new problem, I tried starting up the mod loader recently and, even though it worked perfectly before, it's giving me a new error message.

    "startIndex cannot be larger than length of string.  Parameter name: startIndex"

    I didn't make any changes to the files, it just started giving me this.
