Watching es2xx's 100% run on youtube, following along on a sweet map from
Metroid Map Station, it looks like he actually misses a Missile container in the Pirate Ship.
es2xx video - screenshot of map just before finishing
Missile that was missed?
And doing the count, that would make 144. Which gives 230 missiles (which seems to make a little more sense, since all the other maximums matched that of Super Metroid). Yet still it says 100% at the end?
Edit: Also, with PB early, could you get the power bombs sitting in Chozodia that get stolen later on?
Edit 2: So, watching the rest of the video, you apparently have to get this one during the escape. Whoops!
Edit 3: Still curious about the PBs though, if anyone has that answer.
Edit 7 million: I might have figured that out too - are those the same PBs that you get in Tourian by the Xray (so if you get them early, they don't appear later)?
