So there's Project M. With a little bit of magic, you can change it to be basically your own game. This is a list of changes I've made to Project M.
Costumes
Zero Suit Samus is now upgraded to her SSB4 appearance, with some minor alt changes. One alt is even based on Samus's own suit.
R.O.B. has costumes based on the Wii, GameCube, NES and N64, and even one based on the PlayStation 4.
Captain Falcon has his gold alt from Smash 4.
Yoshi has alts based on Yoshi's Woolly World.
Giga Bowser (and his Dry form) has a very...demonic alt.
Fox has his gray alt from Smash 4.
Peach has an alt based on Vivian from Paper Mario, as well as alts based on Mario and Luigi.
Mewtwo's red, green, and blue alts are upgraded to stand out more. He also has an alt based on Shadow Mewtwo from Pokkén Tournament.
Lucario's black alternate costume is replaced with a yellow and red one based on Ken from Street Fighter.
Snake's default costume is now his sneaking suit from the original Metal Gear Solid.
Roy has a new black and blue alt and an alt based on Link.
King Dedede is now upgraded to his Smash 4 appearance.
Sonic (and Super Sonic) now look like how they appear in the recent Sonic games.
Trivia
- When R.O.B. is being grabbed, in hitstun, being Star KO'd/Screen KO'd, in his "lying on the ground" animation, drowning, or has broken his shield, all while using the Wii alt, you can find a copy of Brawl outside of where the disc would go on a regular Wii. In addition, when normally using Wii R.O.B., the Wii is turned on, indicated by a green light; when in any of the listed circumstances, the Wii is off, indicated by a red light.
- Interestingly, the copy of Brawl is a PAL copy, not an NTSC one.
- In addition, the N64 and GameCube variants have a copy of their respective Smash games, and the NES variant has a copy of Super Mario Bros. inside.
- When using any of the Yarn Yoshi costumes, using Yoshi's up or neutral special will result in a black egg most of the time; in some cases, it will feature textures from characters or items. I can only assume that the game doesn't know what color to use for the Yoshi egg because of the mod (and because, in PM, the eggs change color depending on the Yoshi, much like in Smash 4), and it just decides to use a random texture for the egg instead.
- What's interesting to note is that the on-screen appearance egg, side special egg, and egg shield use the regular green color.
- Gray Fox shows up as normal Fox in All-Star Mode, for some reason.
- Interestingly, the Ken alt for Lucario is just his Shiny alt (from vPM) with a red outfit.
Stages
Battlefield and Final Destination are replaced with how they look in Smash 4.
Flat Zone 2 has a subtle, but big change to it; instead of the stage taking place on a Game & Watch system, it takes place on a Wii U.
Fourside, Port Town Aero Dive, Shadow Moses Island, Brinstar, and Temple are now Ω stages (though some stages still have platforms).
Castle Siege is retextured to look like Amestris from Fullmetal Alchemist.
Halberd is retextured to resemble Galacta Knight.
Frigate Orpheon is replaced with Pyrosphere.
Norfair is replaced with the area from the second boss fight in Super Mario 64.
The Online Practice Stage is replaced with a Project M-style training room.
Delfino Plaza is retextured to look like the hub world from Sonic Adventure
Pirate Ship is replaced with the Merry ship from One Piece
Pokémon Stadium is replaced with Midgar's Ω form.
Skyworld is replaced entirely with a stage based on the Ace Attorney franchise.
Onett's layout is now a duplicate of Smashville's.
Spear Pillar is its normal self, but with no hazards; it also has an additional red variant where Giratina appears.
Princess Peach's Castle is now a traveling variant of Mario Circuit, retextured to look like a Rainbow Road track.
Trivia
- For whatever reason, the on-screen appearances do not activate on Flat Zone 2.
- The same applies to the Merry ship, except it only occurs for the first player (as they spawn on the head of the ship).
- On the second phase of Amestris, you can see a bunch of still images of Alphonse Elric, and, if you have a sharp enough eye, you can see Edward Elric as well (though he can be fully viewable if the camera is moved towards him).
- Temple actually uses its Ω design from Smash 4.
- On Shadow Moses Island, if you manage to land one of Captain Falcon's powered up moves (discussed in the Other section of this page), the pillars will disappear, along with the platforms on them; however, the game thinks the platforms are still there, so you can (theoretically) stand in midair. However, like in the original Shadow Moses Island, the pillars will return to normal after a while.
- When the pillars do reappear, they look different during the reentry animation, but then snap to their regular appearance after fully reappearing.
- The acid still rises in Brinstar, but it affects the fight in no way (most of the time).
- There's like a 1% chance that you can hit the acid when off-screen, though I wouldn't recommend trying it.
- The AI still expects to be hit, so sometimes they just plummet to their doom.
- Oddly, they do the same thing in Distant Planet.
Characters
Wolf's model and moveset are replaced with that of Ryu's.
Donkey Kong's blue alt is replaced with Sonic the Werehog.
Link and Zelda's models are replaced with how they appear in Hyrule Warriors.
The Ice Climbers's models are replaced with the Game Grumps.

Sonic's Shadow, Tails, and Silver alts are replaced with an actual model for Shadow, Tails, and Silver.
Snake's white costume is replaced with the Terminator.
Ike's model and moveset is replaced with Cloud's.
Peach's Daisy alt is replaced with an actual model for Daisy, and her blue alt is replaced with Rosalina.
Ivysaur's model is replaced with Duck Hunt.
Samus's model is replaced with Alphonse Elric from Fullmetal Alchemist.
Lucas's model is replaced with Ashley.
Kirby's model is replaced with the Hyrule Temple.
Ganondorf's Brawl model is replaced with Sauron from Lord of the Rings, and his Melee model is Johnny Bravo.
Sheik's model is replaced with Mai Shiranui.
Jigglypuff is an Oreo.
Falco's head is now Toucan Sam.
And Meta Knight's model is replaced with a shopping cart. Yes, you read that right: a shopping cart.
Trivia
- In All-Star Mode, Aipom will, for some odd reason, show up as regular Diddy Kong.
- Despite being a texture mod, Natsu doesn't use any weapons that Pit owns; his bow, shield, and even wings don't show up.
- When using Rosalina, the items used in her side smash are replaced:
- When using any of Daisy or Rosalina's moves (most notably, the side special), the eyes eerily moves to the far right, almost completely out of sight.
- One of Natsu's recolors is based on Gray Fullbuster, also from Fairy Tail.
- Pressing A after the first hit of Ashley's down smash or trying to angle Ashley's side smash causes her to appear in a T-pose; however, this has little to no affect on gameplay, as you can move at any time. Perfect shielding the attacks also seems to cause this.
- With the side smash, her magic wand is also included in the T-pose.
- In-game, Aipom has a much bigger head than Diddy; however, this doesn't actually change his hurtbox.
- Additionally, in some cases, his tail clips through his head.
- When using Vine Whip as Duck Hunt, he uses a chain instead of a whip. However, the texture for the chain seems to be some weird static-like gif. It's always moving, even when the game is stopped on a frame via the debug menu.
- Interestingly, in All-Star Mode, Samus's model is being read as an older mod I had where it replaced Samus with Zero Suit Samus. I'm not sure why this is the case.
- While Ryu's moveset is mostly being a one-to-one transition from Smash 4 to Project M (right down to the differing Final Smash), barring the removal of Ryu's special inputs, the mod does add one new gimmick of its own: when Ryu has taken 50% damage or more, he is able to hold his down taunt, and transform into Evil Ryu, whose moveset features a new down special, as well as incorporating the darkness and electric effects into some of his moves. His Final Smash also changes to the famous Shun Goku Satsu.
Voices
Wolf, going with his Ryu mod, has Ryu's voice clips.
Ike, going with his Cloud mod, has Cloud's voice clips (some even in English).
Kirby has voice clips from famed YouTuber JonTron.
Marth, going with his Lucina model replacement, has Lucina's voice clips.
Pikachu has voice clips from famed YouTuber Egoraptor.
Roy, Lucario, and Falco use their voice clips from Smash 4.
Sonic has voice clips from Roger Craig Smith (not his clips from Smash 4).
Bowser now has reused clips from Mario Kart Wii.
And possibly the best addition of all, Fox uses his classic voice clips from Melee.

Trivia
- Captain Falcon's replaced victory theme isn't just a small excerpt from an F-Zero game; it is instead the full Finish theme from F-Zero GX, which includes the results theme from said game. This makes Captain Falcon one of two characters with a different results theme, the other being Sonic (as his results theme has both the Level Clear jingle and the results theme).
- Technically, Pit makes three, since his victory theme is more of a full-on song.
- Sonic's victory theme has gone through the most changes. It went from the original to the Level Clear jingle from Sonic Colors, to the Xenoblade Victory Theme from Smash 4, to the Level Clear jingle from Sonic CD, to the Level Clear jingle from Sonic Generations.
- In contrast, Melissa has gone on the most stages. It moved from Final Destination, to Battlefield, to Castle Seige.
- Infinite Glacier, Final Destination, Skyworld, Green Hill Zone, Battlefield, Dreamland, Princess Peach's Castle, Onett, and Skyloft are the only stages where all of the songs are replaced by me.
- Not counting Dreamland (and, to a lesser extent, Fountain of Dreams) or the victory themes, the Kirby universe is the only one without replaced music.
- In contrast, the Sonic and Kid Icarus universes are the only ones that only have replaced music.
- Theme of Samus Aran, Space Warrior is the only unchanged song to change stages.
- Fountain of Dreams comes close to that title as well, as it does appear in vBrawl.
- Due to the way the Subspace Emissary works, some of the SSE cutscenes have replaced music in them, and the outcomes are quite hilarious. Notable examples include "The Pig Statue Targets Lucas", "Link's Misunderstanding", and "Samus Revived".
Other
Captain Falcon has an interesting, yet hilarious mod for his moveset; his dash attack, forward air sweetspot, neutral special, and side special all cause 999% damage, make a huge explosion that engulfs the entire stage and then some, and makes all opponents die.
Pit's Final Smash is a little different; Palutena and the Centurions are replaced with a bunch of Rare Pepes.
Several announcer voice clips are replaced with GLaDOS from Portal.
The Ping sound effect is replaced with the MLG Airhorn.
Mario's Fire costume has a golden metal texture color.
Ness's forward smash uses the SMAAAASH!! sound effect from EarthBound.
Sonic's metal texture is now based off his metal skin from Sonic Heroes.
Zelda has bigger boobs.
Peach's turnips now have meme faces on them.
Roy's jumping animation now matches the one he has in Smash 4.
Snake's side taunt involves him dancing, as opposed to speaking into his codec.
Mr. Game & Watch now has a fully animated three dimensional model.
Bowser now uses Flying Slam instead of Koopa Klaw.
Sonic's purple alt now aesthetically has NiGHTS's bracelets and shoes.
The All-Star Rest Area is replaced with its Smash 4 variant, music and all. It even uses the Brawl trophies in the background.
Trivia
- Captain Falcon's mod makes it so his dash attack also has the flames from the Falcon Punch.
- Like Yoshi's egg (see here), Mario's Cape uses a random texture when it can. However, it doesn't show up as black initially; it shows a color similar to Mario's overalls.
- Because Mr. Game & Watch's model is now fully animated, it leads to some...interesting views, to say the least.
- Also worth noting is the fact that he remains three-dimensional on Flat Zone 2.
- For whatever reason, jumping while using Octopus causes the game to freeze.
- The Smash 4 All-Star Rest Area uses portraits for each character as they appear in Smash 4, with the following exceptions:
- The Ice Climbers and Wolf use their trophy poses from Smash 4.
- Sheik and Zero Suit Samus do not use their portraits, regardless of who is fought in All-Star Mode, as they are not separate from Zelda and Samus, respectively.
- Snake has a non-existent portrait, instead having an image with a random number on it. When the game is paused, it is replaced with the text "Back: Quit: +".
- Marth and Roy share an icon, due to both Brawl not having an icon spot for Roy and Project M not adding one in.
- Wario, despite being defaulted to his overalls in Project M, has his biker portrait. Weirdly, his head icon is also changed.
- Charizard does not appear in the icons, despite having one of his own from Smash 4. Instead, the fourth slot goes to Mewtwo, who does not use his appropriate portrait from Smash 4.
- Strangely enough, it is possible to SD on the new All-Star Rest Area. You don't respawn, though.
- Additionally, the stage remains untouched if you go into Boss Battles, despite it literally using the same layout.
