Thanks to Serenes Forest we can read about a list of differences that were found in the prototype version of Fire Emblem 7, a beta that was leaked online sometime ago. Major differences are in the colors of the CGs, options, sprites, animations, extra shops and items. The 2 betas can be download at the Hidden Palace archive.
U64 is an archive with articles, screens and videos for cancelled, beta & unseen videogames. Every change & cut creates a different gaming experience: we would like to save some documents about this evolution for curiosity, historic and artistic preservation.
