Marcel sent us a couple of screens from an early version of Aerogauge, an F-Zero clone that was released in 1997 for the Nintendo 64. It seems that the HUD was different, but as we never played the final game, we dont know if there are other interesting beta differences. Maybe someone else will be able to notice more differences!
A video from the retail version, the same stage: we can notice the hud changes and different textures. The “car” seems almost the same as the beta version
