Total time to complete this process: ~15-20 minutes. This also works with the new PaletteSwap update on gamebanana bringing 20 brand new characters to the game.

1. Back up your game files
2. Where to find skins
3. How to decode which character is which
4. Update the skins
5. TEST THE SKINS
6. Enjoy :)

Anytime you are altering game files, the first step is to create a backup that can be used if there are any issues down the road. You'd be surprised at how many skins seem to have issues from time to time and you will be happy you had a backup. Depending on where you installed your game, you may notice that it is in the C:, D:, etc.

How to find what drive it is installed in:
1) Open Steam
2) Click the Library Tab
3) Right Click on Ultimate Marvel vs Capcom 3
4) Click Properties
5) Click Local Files
6) You will see the drive letter in blue towards the middle top of the page and the size ~3.52gb

Now that you know what Drive you installed it in, the path should be the same as below as long as you Swap the starting D:\ path with the drive letter we just checked in the Local files step above.

Folder path for your files:
characters: D:\SteamLibrary\steamapps\common\ULTIMATE MARVEL VS. CAPCOM 3\nativePCx64\chr\archive
actual game save: /c/program86/steam/userdata/xxxxxxxxxx/357190

I have a folder on my external hard drive labeled Backups. Within that folder is a UMVC3 folder that contains both the character backups and a folder for my actual game save.

Create the folder for your backup wherever you would like, Copy and paste the characters from the referenced path above into this new backup folder.

NOTE: If you dont want to do this, you can just uninstall the game from steam and re-install the game. The total game is around 3.5gb so it doesn't really take that long.

Gamebanana - One of the biggest locations of modded skins, there are large packs, individual skins, MCU version of characters, even the Herald alternates for each fighter. **I would recommend gamebanana and the palleteswap update that was released in January. This one download contains 20+ characters including Thanos, Cyclops, Psylocke and many more.


Reddit - reddit r/MvC3/ - Majority of the mods posted here are OC or user made posted in google drive folders and other means. In general this is another solid place to find custom or modded skins.


Gamewatcher - Decent collection of skins, special effect recolors, music and other packs. Similar to the items in Gamebanana but I have seen a few unique ones here.

Each character is not labeled with their name but instead a Hex Code. When you are replacing the skin for a character, locate their corresponding Hex Code.

Character Arc IDs
Character .ARC files location: \ULTIMATE MARVEL VS. CAPCOM 3\nativePCx64\chr\archive\
00XX_YY.arc => where XX is the character, YY is the costume slot

00XX_00 (default costume)

00XX_01 through 00XX_05 (the other color versions of the default costume)

00XX_06 (H&H Color)

00XX_07 (Alternate)

00XX_08 (gold H&H) - only Akuma, Doom, Wesker and Dorm have this

Example: 0032_05.arc is Taskmaster's 6th costume slot, his black regular costume.

Once you have identified the corresponding Hex code, head to the skin folder and drag the new skin into it. Keep in mind that the skin has a specific slot to go into and will take its place. This will ask if you'd like to replace the current skin and you can press yes since you've already created a backup.

It always helps to double check you are dragging the correct new skin into your main skins folder.

**Special Note if this is the PaletteSwap Update!!! There is an extra folder which contains I believe the sound for 3 characters, thanos, cyclops and 1 more character. Make sure you drag the 3 files that are in the sound folder of the download into the sound folder of the game which is located almost exactly where the skins are.

There are some skins that seem to work fine for other people but regardless of how many times I attempt to install, the game hard crashes if its picked for a fight. It's an inconvenient crash when you are fighting with a friend and have to boot the game back up. You will know the first time you try to launch up a battle with a modded skin if it will work for you.

My suggestion is to try them all by yourself first and if it crashes, replace the specific skin you've just tested with either the original from your backup skin folder or an alternate modded skin. Whether its the training room or Arcade mode, testing is always recommended.

**Nearly all of the paletteswap skins work with no errors on my end locally. The skins that are 1 offs on game banana are typically the ones that break.

You've done it! The hard work is over and any new skins can be added that you find over time. There surprisingly are skins still being created and added all the time which is exciting.

If you play online with the same few friends and they want to see the same modded skins you have, feel free to create a zip folder of your skin path and share it via email. They will obviously want to back up their skins as well for future use but having the same modded skins installed means if someone selects Sentinel with the captain america skin, both parties will see that during the fight. Sharing is caring.
