If you played with Mewtwo after the launch of the character in Super Smash Bros last week, you may have noticed some glitches and bugs playing with the character online, and on various other modes. Nintendo Japan said they were working to fix the the problem and now they have! The new update 1.0.7 went live today and fixes all the bugs, allowing you to play with Mewtwo safely without any problems, for both 3DS and Wii U. The 3DS update is 1700 blocks, and the Wii U update will take up 21MB of space.
New Super Smash Bros Update Fixes Mewtwo Bugs

1700 blocks on 3DS? wtf? First they make character glitch our games and then eat all the space from our SD cards.
Buy a goddamn 32 GB sd card.
1700 blocks isn’t actually huge. In fact, we don’t know what the exact MB size is.
One block is one megabit, or 1/8 Megabyte
Even more reasons to change that dumbass “blocks” info because nobody knows what the fuck it means.
If you are having problems with update download sizes, you can actually delete the previous update data, and then download it again from the eshop. This is possible because the space the update takes is not the same it requires in order to be downloaded. Worked for me.
Well… Ok, just patching MewTwo… now I just have to wait for a relase…
Wow, that took up a lot of space for just fixing some glitches…
Nice and quick. I like it. Filesize is of no concern to me, especially on my 3DS.
This glitch never effected me but to those it did, I hope somehow they got all their save data back.
But IDK how that would be possible..
It just disables online play for the most part and might corrupt data by chance.
I had to get another sd card to download new leaf from club Nintendo anyways so right now I’m rolling in dat data space. As for Wii u I’m not sure how much I have
I cannot get the free download to work for my elite status
That’s a lot of Wii U MB for a patch. Why the hell is it so much?
Calm down, more than likely this is a replacement patch, meaning it fully replaces the previous one only changing the glitch information. However, to download you do need the full 1700 blocks free. Installed space is likely not affected much (assuming there isn’t anything else added). Of course, same for the 21mb on WiiU.
But what about the custom moves
As long as it’s been fixed, that is what matters. Regarding the file sizes, I’m rolling in data and I didn’t even buy a 32 GB SD card for my “new” 3DS XL or an external hard drive for my Wii U. All retail copies ;3 Except Captain Toad and Darksiders II.
21 mb is too big? Seriously people?
>>>It’s the cattle as usual, they don’t know anything>>>
Heh, tell me about it, Mb is the smallest grain on memory, from MB, goes to GB, GB goes to TB.
MB = Mega Bite
GB = Giga Bite
TB = Tera Bite
Low
Medium
High
Sigh. They must be trolling but not in a very smart way.
>>>No, they are just young, corrupted by the Xbot infection to hate everything that’s “in” right now, in other words, Nintendo>>>
I think load time super smash got a lot slower after i installed mewtwo.
