It will be useful to everyone who plays GTA UNITED.
Just drop a new executable (gta_sa.exe) into the folder with GTA UNITED and all user files for the GTA UNITED mod will be stored in the "GTA UNITED User Files Folder" folder, instead of "GTA San Andreas User Files".
This will allow you not to confuse your saves and have more slots for saving, as well as personalize your settings, gallery and your music for GTA UNITED. Let me remind you that in the User Files folder the game stores saves, settings, user tracks and a gallery (pictures taken using the in-game camera). Since GTA UNITED uses gta_sa.exe with modified limits, in my file the limits are set identically to the original gta_sa.exe from the UNITED mod.
Just in case, I have included a limit patcher in the archive, although if you did not delete it, it should be in your game root after installing the GTA UNITED mod (patch_gta_sa.bat). If the game somehow behaves, which is unlikely, try running this file. Please report any issues with this fix in the comments. This way you will help yourself and others.
