Mega Man 8, known as Rockman 8: Metal Heroes in Japan, is the eighth installment in original Capcom’s Mega Man series, and was originally released in Japan on the Sony PlayStation on December 1996. The following year, Mega Man 8 saw a release on the Sega Saturn and was localized for both consoles in North America and the PlayStation in PAL regions. Director Hayato Kaji revealed that he initially designed Duo as robot created by the Mega Man 4 character Dr. Cossack. When it was decided that Duo would instead come from outerspace, his appearance changed but still retained remnants of Russian traits, such as his headware. [Info from Wikipedia]

Thanks to Proto1, we found out that MegaphilX uploaded an interesting video from a Mega Man 8 beta in his Youtube Channel.

Everything is practically unused in the footage. The background, the effects, no bolt item, Mega Man’s got a strange running animation and towards the end of the video, you can see early footage of the stage select screen. The bosses have not been made yet, so their Metools act as their temporary icons. Also, a sprite of Duo appears here as well, something that isn’t in the final at all.

– Completely unused BGM
– The background for the stage is unused and unfinished.
– Mega Man has an odd running animation. He’s very stiff in comparison to his final running animation
– His color when using the MegaBall is Green and Yellow instead of Pink and purple.
– Enemies appear at places they don’t usually in the final.
– Big yellow blocks have a blue streak through them. In final, they’re solid yellow.
– at one point in these videos, there’s an elevator lift moving downwards. In the final, elevators never go down, only up.
– No enemies in elevator portions.
– No hit detection with Whale Airship enemies.
– Bolt items weren’t implemented yet
– Beginning at 5:04 in this video, you can catch a quick glimpse at a work-in-progress stage select. Mettools represent stages under construction, and the Duo character is shown as the boss for the Island stage. Duo isn’t a boss in the Island stage, so perhaps he was in this particular build.
– Also at the stage select, Tengu Man’s mugshot appears on the top right column where Frost Man should be. In the final, he’s on the top left.

Thanks to Proto1 for the contribution!
