TL;DR on the bottom.
shinyquagsire23 looked through the fighter table and found this:
After Mewtwo + 7 there are 5 additional “Mario”s listed. This means, that there are 5 additional unused characters in the fighter table in the latest update. Right now, we know for sure that Lucas is coming. After Lucas, it is heavily suggested that Roy (Fire Emblem) and Ryu (Street Fighter) will be incoming as DLC. Therefore, we have two additional slots for DLC. Whether the two slots will be used for the ballot results, or for pre-ballot result DLC is unknown. Stay tuned for additional information.
On April 15th, 2015 Club Nintendo users finally had the chance to play as Smash Veteran, Mewtwo. With the new fighter an update was released for both the 3DS and the Wii U which introduced a number of gameplay balance changes, and support for upcoming DLC. However, this news was quickly overshadowed by future DLC discoveries.
shinyquagsire23, an active member of the 3DS homebrew scene, posted on reddit claiming that there was a number of unused tracks in this update. The tracks were housed under a new folder, thus indicating that they were accidentally left in. Based on the numbering and names of these tracks, users were able to quickly figure out what the tracks were. The biggest shocker was that Ryu (from Street Fighter) and Roy’s (From Fire Emblem) victory songs were included in this folder– two potentially previously unannounced DLC fighters. Because of this, the Internet went on fire as users within the Smash community tried to find additional sources to confirm. Around 10 hours later, additional confirmations started to pour in as other data-miners and hackers backed shinyquaqsire23’s claims. Now, there are over 5 unique confirmation, which further proves that these files are indeed left in the update.
Below, are the list of files that were accidentally included in the update:
Based on the track naming convention within Smash, users were able to identify the music tracks.
“MoriStage” is the Forest Stage song from Kirby’s Air Ride.
“Sentou Zekrom Reshiram” already exist the base version of the game. The file was updated in a previous patch.
“Ryu” is Ryu’s Theme from Street Fighter 2.
“PupuLand” is the N64 remix of Dream Land from Kirby Super Star
PacMan is a song that already exists in the base version of the game. Reportedly, it was altered in this latest patch,giving further credibility to this data-mining.
Mewtwo, Ryu, Lucas and Roy are all victory songs.
We can decipher the meaning behind the tracks not only by listening to them, but by the naming convention.
What Do You Mean, ‘naming convention’?
Brawl introduced a unique track naming system. This system is relatively straight forward once you look at the tracks. However, let me quickly break down some tracks:
First off- snd_bgm indicates that the track is background music.
The first letter indicates its part of group “A”, which in Brawl and Smash 4 translates to the Mario series. 53 is the track number within that series.
MKT8 indicates that the song is from Mario Kart 8. “Rainbow Road” is the name of the track. The last number indicates if there has been a revision.
A = Mario
56 = track number in Mario series.
GLX = Mario Galaxy
Super Mario Galaxy theme song.
The Smash 4 system builds upon the existing Super Smash Brother’s Brawl system. Brawl’s system was even ordered by release date of games, which allowed users to identify some of the tracks that have been completely dropped or deleted from the game. Smash 4 new songs are placed immediately after Brawl’s songs. Below is a list of the series letters:
A – Mario
B – DK
CRS – Menu music, music for modes
E – Yoshi
F – Kirby
G – Starfox
H – Pokemon
I – F-Zero
J – Fire Emblem
K – Mother
L – Pikmin
M – Wario
N – Animal Crossing
O – Is missing. Was missing in Brawl.
P – Kid Icarus
Q – Famicon ・new series
R – Game and Watch, Punch Out, DS, Other ・Additional new series
S – Megaman (Used to be Metal Gear in Brawl)
T – 64 Songs
TEST1-5 – blank files, for testing purposes
U – Sonic
V – Pacman
W – Melee Songs
X- Music from Brawl
Y – Only two tracks here: snd_bgm_Y05_SBX_BossSentouKyoku1 and snd_bgm_Y07_SBX_BossSentouKyoku2. The two boss battle tracks. (Presumably for Subspace)
Z- Fighter related tracks (winning theme music)
New Kirby Stage:
Since there are two new Kirby songs, it would appear that Kirby is getting a new stage. Frostwraith, an active member of SmashBoards noticed in several 3DS Classic playthroughs that if the Kirby path was chosen, it would now sometimes load Battlefield instead of Dream Land. Theoretically, this is because the game is trying to load a new stage that isn’t in the current file set.
shinyquagsire23 investigated the stage table in Smash 3DS, and found that the number of additional slots was increased from 4 to 14. However, because each stage has both an omega version and a regular version the actual number of potential extra stages is increased from 2 to 7.
“Z” Fighter Numbering:
Bold, and caps lock so people will read it:
NOT ALL OF THESE FILES ARE IN SMASH 4. I’M SHOWING A THEORY OF WHAT A COMPLETED LIST LOOKS LIKE SO PEOPLE CAN BETTER UNDERSTAND THE MEANING BEHIND THE TRACK NAMES THAT WERE FOUND.
Fighters that were missing for a version were given new numbers in the newest version. See Mewtwo for definitive proof. This means that Lucas and Roy will also get a new number when they are released.
64 Fighters (Notice the lack of Jigglypuff)

Smash 4 Section
(Smash 4: Clones and Altered characters first)
75 – ? Reserved number? (NOT IN SMASH 4)
76 – ? Reserved number? (NOT IN SMASH 4)
(Updated File List)
The “Z” number order is further proof that Jigglypuff wasn’t a priority in Brawl. Also, since there are no missing numbers in Smash 4, it could mean that the Rhythm Heaven representative didn’t get very far into development at all. Most investigation will be done into both of these topics.
Please note: because this folder was only accidentally left in the 3DS version, there are no files present in the Wii U version. Here’s the list of files included in the update. (Provided by soneek).
Possible Fighter Pack Incoming?
It’s possible that a fighter pack will be released with these three characters. Currently, there is no price listing for Lucas on all versions of the Super Smash Brothers site. The release date is slated for June, which will probably coincide with E3. Ryu and Roy would be huge reveals for Smash DLC, and it makes sense to announce both of them at E3.
NEW INFORMATION: 5 additional “Mario” was added to the character database. 3 of them will probably be used for Lucas, Roy and Ryu. The other 2 are currently unknown.
Ryu from Street Fighter and Roy are very likely going to be DLC in Smash 4.
Their numbers indicate that they were started along with Lucas, possibly even with Mewtwo.
There’s additional stages incoming (up to 7). One of which is possibly a Kirby stage due to the number of new Kirby songs that were included. Possibly Dreamland from Super Smash 64.
