I have been pondering why has no one done a 100% run of this game yet for this site?

There are a few tricks actually this video is of Mr_Shasta playing it at SGDQ in 2015 but other than that no i don't think there is much difference.

Is there a reason why no one uses the Famicom disk system to run Metroid? I ask because i honestly see no difference in time advantage.

It may just be preference but i would like to know as i have not really seen any runs on the Japanese version of the game.

Well if i can find the game in the app store then i might consider it

I was wondering how do you record a IOS devise?
