Hidden Details: Binary Byleth (Patreon)

 Welcome to the seventeenth episode of the revamped Hidden Details blog!

Have you found some obscure reference or detail in this comic? A JoJo reference? A sneaky little Loss? A callback to a previous comic? Let us know what you've found in the comments! Every detail that has been found will be added to the list below. Once everything has been found, this comic will officially be marked with "all details found".

The Patron who has found the most Hidden Details at the end of the year might win something nice... We still need to do the big reveal of last year's winner though!

Please only comment with ONE hidden detail or reference!

I'm going to help you a bit. I've ordered these details into categories. Also, there's no Loss and no JoJo reference in this comic.

General:

1: Marth says something along the line of 'Sorry, I don't speak English yet...', to which Fox replies 'Ah that's okay, me neither!'. This is a reference to the fact that Marth spoke Japanese in Melee (even in the North American/European version). Fox did have some English voice lines but they were obviously done by a Japanese voice actor. Found by James Patrick Victoriano
2: Furthermore, Falco is seen learning his English lines from a book called 'English for Video Game Characters'. Found by Marwan Abunura
3: All the fighters in 2001 have their old Melee designs (Mewtwo's huge head and long fingers, Roy has a babyface, et cetera). Found by Zoe Kunz
4: Sakurai is wearing a GameCube shirt in 2001. Found by Toon Draw
5: Sakurai has a glorious mustache, long hair and white Nike shoes in 2001. He didn't have those in reality back then, but it's fun to imagine he did.
6: Only the newcomers are wearing 'Hi, my name is...' badges. Marth, Roy and Falco have written their names in Katakana, since they can't read/speak/write English yet. Found by CrazySeanDX
7: In 2020, Sakurai has changed his shirt to a Nintendo Switch-branded shirt. Found by JakiStow
8: The nametags on the two Byleths read 'Byleth' and 'Also Byleth'.
9: All the fighters in 2020 have their Ultimate designs (Mewtwo's proportions are normal again, Falco doesn't have his huge beak anymore).

The two wide panels take place in the same room, but things changed in the past 20 years:

10: The little village outside the window grew into a huge city with skyscrapers and everything. Found by AquaticMadman
11: The plant grew big. I did some research into long-living plants and the Hosta apparently can live longer than 15 years, so I made sure to make it look like a Hosta. Found by Phloxiana
12: The walls got a fresh new layer of white paint.
13: The flags have changed colors from 'Melee purple' to 'Byleth green'. Found by Alex Nelson
14: The huge CRT TV has made room for a flatscreen in 2020. Found by Zach

Lastly:

15: Balthazar's butt is visible among the Fire Emblem fighters. Found by Hunter Poirier
