Final Fantasy C2 is a Japanese Super Famicom/Super NES ROM hack that remixes elements of Final Fantasy IV to loosely retell the story of Final Fantasy II. It uses Final Fantasy IV as the base, meaning it still uses FFIV's leveling system, music, room layouts, town layouts, etc.
I've translated this ROM hack into English and released two versions of it:
You can download the patches here. Be sure to read the readme file too for patching instructions and more.
I've also released my tools + files + source code here, other FFIV hackers/translators will probably find it helpful or interesting in some way.
