Final Fantasy: Dynasty Prelude

Final Fantasy Dynasty Prelude is perhaps one of the most controversial MZX games of all time, as well as one of the most hyped (and anticipated, at least back when it was being worked on).

A demo for FFDP was released on mWorld in 2000(?) but was intended for use by Square of MegaZeux members only, and was password protected despite being uploaded to the public mWorld archive. The password was eventually cracked by a community member.

In 2001, Ryohei released The Lost Summons of FFDP, a graphical showcase of the summon magic effects that he created for the game when it was in development.
