What is JuraviS?

JuraviS is a cross-platform tool written in NodeJS that allows users to easily create and patch mods. It can also be used as a debugging/cheating tool. Originally it was developed for Final Fantasy Tactics, but the author Xifanie felt that a new broad patching tool was necessary in the video modding community, and thus painstakingly edited her come to allow any game to be edited by the program; within language limitations, of course. The newest version of NodeJS operates on a 32-bit standard, which can be constraining.

It is open source, but sadly currently with little in-code comments.

The software is still in its infancy and currently mostly focuses on implementing features specific to Final Fantasy Tactics.
