ROM hacks by my friend Spooniest.
Final Fantasy II Rebalanced (v1.0 - 7/16/15)
Starts you with better stats, skill levels in your equipped weapons, and a basic survival kit of magic. It makes the game simple to pick up and hard to master, but not nearly the three-ring slaughterfest that the vanilla version is.
Final Fantasy IV - J2evisceration (v1.0 - 4/2/16)
It removes the swearing from the game script, corrects several translation errors, removes non-canonical lines from the script, and changes the font and spell names back to their SNES counterparts.
Final Fantasy V: Legend of the Crystals (v2.1 - 2/28/21)
Legend of the Crystals is an attempt to modernize the now nearly-two-decade-old translation of Final Fantasy V done by the fine folks at RPGe. No gameplay changes were made to this, so your stats’ll work out fine. Take a trip back to December 6, 1992… Enjoy!
Final Fantasy VI: RPGONE Alt Menu Font (v2.0 - 4/1/2016)
