About
Mods allow you to change nearly any aspect of the game, including, but not limited to: music, movies, SFX, character/NPC/enemy models, gameplay, battle/world/field textures, animations, skill/spell effects, user interface, dialogue, tweaks and cheats, and more.
7th Heaven is unique in that it lets you easily activate and deactivate mods using a convenient user interface (GUI) without needing to permanently alter your game or mess with complicated mod file/folder installs. You can quickly try out a mod and keep or uninstall it without affecting your game installation. It accomplishes this by intercepting (hooking) the game's requests for resources (models, music, textures, etc.) and instead supplies an alternate copy of that resource from the mods you have installed and activated. There is no need to uninstall and reinstall Final Fantasy 7 if a mod causes a problem or is no longer desired.
