You may pass this off as another “Sega Allies with Nintendo” rumor, but take a closer look–apparently this news comes out of the mouth of the president of Nintendo. From The Magic Box:
Yamauchi, president of Nintendo mentioned that they have no intention to discuss and sign contracts with Square. This rules out the possibility for Square to bring Final Fantasy IV, V and VI remakes to Gameboy Advance. However, Yamauchi mentioned that they have made an agreement with Sega on supplying game software for Gameboy Advance.
We’ll follow developments…it’s a very interesting thing to expose especially considering Sega’s deal with Pace made today.
