A free program for Windows, by Team FCOM.

FCOM Convergence is a mod for the popular game, Final Fantasy Record Keeper. In this game, you can import and play with characters and monsters from a number of popular Japanese RPGs. The most popular of these is Final Fantasy Record Keeper, which allows you to play with more than 30 monsters, including a large number of monsters from Final Fantasy.

The main purpose of this mod is to let you play with different kinds of monsters in a single game, which is not possible with the normal Record Keeper. In addition, it also lets you import your favorite monsters from other RPGs into Final Fantasy Record Keeper. This mod can also be used with other games that use Record Keeper.
