Introduction: How to Build Your Own MUGEN Roster

Picture of How to Build Your Own MUGEN Roster

Have you ever wanted to make your own fighting game but didn't have the time or the knowledge to do so? Well MUGEN is the first step for any fighting game fan with these dreams to start. With MUGEN, you can build your own fighting game with all the characters you wish, just look at mine for example. Building a MUGEN is very simple and will only take about one day to learn! Perfect for anyone with a weekend appetite for gaming! So sit back and let's explore the world of MUGEN!

Step 1: Download MUGEN

Picture of Download MUGEN

 First step is to download MUGEN. The site is here. Once you download it, unzip it using whatever program you wish, I use 7Zip. This is the basic MUGEN that most people start out with. Very bland, gray and has two characters with 12 slots for more characters.

Step 2: Find a Screenpack

 This boring screenpack will not do for us. A screenpack is MUGEN term for the whole system. All the menus, the character select and more. The characters and stages are their own separate files, so we will get to those later. You can find other screenpacks here.
The screenpack that I am using and will use for this instructable is IMT (Blue) by user Acey. It can be downloaded here

I recommend this one as it can hold as little as 70 characters, a good start for anyone. Mine hold's 336, which also comes with the pack.

Some MUGEN screenpacks do not include the program and require you to copy all of the contents of the screenpack into the default MUGEN you downloaded last step. This one, the author was nice enough to give us MUGEN with it, as well as a very helpful program called VSelect, but we will get back to that later. Special thanks to the creators

Step 3: Get Characters

 After extracting IMT from it's compressed format, the next step is to get some characters to populate your game! For this step, we will yet again visit Mugen Free For All. Here, everyone is so nice they ordered everything into neat categories, with COLLECTIONS being the place I head to the most, for convince. Let's start with these. Six characters from MARVEL Vs. Capcom 2. Fair enough. Download the file.

After extracting the files, your folder should look like this (I renamed the IMT (Blue) folder to MUGEN Instructable. )

Step 4: Adding the Characters

Picture of Adding the Characters

To add the characters to the game, copy the folders and paste them inside the 'chars' folder, which is located inside the IMT (Blue) folder.  Next up, we need to add them to the actual code! This may sound difficult, but if you can type in the characters name, you can code them into the game. To code MUGEN, go to the 'data' folder. This is enough to make some of you panic most likely, but don't worry, you won't touch most of these components! Instead, go to the IMT04 folder. Here will be an image file, and two .def files. 'Select' controls your characters and stages and 'system' is, well, the system. Open the select.def. You may be wondering how, as you most likely have never heard of a .def file before. But simply open the file with Notepad. Yes, Notepad. Now everything is in clear English. 

Under [Characters], simply type the name of the character. Your first few lines should now look like this.




And Ta Da! Open MUGEN and there they are! 

Step 5: Adding Stages

Now what good is a fighting game without a good venue?? To get a stage, we are heading back to the wonderful people at MUGEN Free For All! Let's take a basic stage from Street Fighter II, Guile's Stage. Extract the folder and place it's contents into the 'stage' folder. Open up your select.def again, and scroll to the bottom, where you'll find [ExtraStages]. It should look like this. 

;Put extra stages here. They will be available in VS and Watch modes.
;For example, you can insert "stages/mybg.def".


Below stages/Stage0.def (the training stage included with MUGEN), add stages/guilestageDG.def

What this does is tell the game to simply look in the stages folder, and pull out that specific file for use as a stage. Boot up MUGEN's VS Mode, select two characters and pick the stage. Congrats

Step 6: Finishing Touches

Picture of Finishing Touches

This is most of what you need to set up and start building your own personal MUGEN roster. But there are a few things that I should note. Below the [ExtraStages] in the select.def is [Options]. [Options] controls the order of who appears in Arcade Mode. To make a character appear later in Arcade Mode, simply add ",order = x" with x being a 1-9 number, 1 appearing first, then 2, etc. Say I want to fight a few level 1 characters then fight a level 2 as a boss. Everyone is level 1 automatically, so just add ,order = 2 to your boss, for this example, I will use Magneto. Make sure you change your values under [Options] to this

arcade.maxmatches = 3,1,0,0,0,0,0,0,0,0

This simply means that you fight 3 level 1 characters, then one level 2 car. It should look like this. 


Magneto, order = 2


And with your [Options], Magneto should now appear after you beat 3 randomly selected characters.

And that's about it! Congratulations! Now go amaze your friends with your fighting game skill!

the easiest way o add characters is to use a program called VSelect. You just drag and drop the .def file of each character into your preferred select screen, save and you're done.

RileyC13 (author)2016-03-11

Can you make your own characters and import them into the game

TJenkins006 (author)RileyC132016-11-15

yes you can but you need sprits and the knowledge to code in a move set and hit boxs

FrederickK5 (author)2016-06-01

soulpancake (author)2016-04-25

Error message: Can't open config file data/mugen.cfg.

Error reading data/mugen.cfg

It won't go in the game and I also tried running as administrator but still won't work why is this?

iAmTheWhite (author)2015-04-19

I cant open .def files, what program do I need to open those

dufer awyn (author)iAmTheWhite2015-08-25


right click - open with - notepad.

dufer awyn (author)2015-08-25

In the IMT01 skin (8400 char screenpack) there is categories for your characters.

Does anyone know how to change the category names? I tried editing it in the select.def file but it does not make the change when i start the program. I also could not find the list in the system.def file.

I would like to make my own categories and eliminate some of the ones i know i will not use. Any help is appreciated.

NearN1 (author)2015-07-30

Help! My characters are appearing outside the boxes.

dufer awyn (author)NearN12015-08-25

You placed your char files in the portion of the notepad that said "blank" it is left blank because if you place a character there it will appear outside of the box. Scroll down in your notepad until you see "CharName[001]" or "kfm" (stands for kung fu man) and replace that with your Kekashi file name. Then Kekashi (or whomever you choose) will appear in that slot. Sometimes the characters you download do not have icons that fit into the small sized boxes that this screenpack has, and they will appear elsewhere, however (in this case) you should still be able to select the character on the block he is suppose to be inside. The picture may just appear elsewhere.

Ok I'm having this problem...There's a blank spot in front of Snake and I can't figure out why...can anyone help please?

MosesP (author)2015-03-08

tried mugen on files but still will not work/characters wont show

YukariA (author)2015-01-09

What is the name of the screenpack in the first picture? please reply thanks :D

Timothyjbushey (author)YukariA2015-03-04

it's the same one that he linked for you to download, there are 4 different options. Each one looks different because they vary in roster size, the first image is option 3. To get option 3, go into the data folder, select the Mugen file (CFG) and make sure there is a ; in front of the word motif for options 1,2 and 4 and remove the one in front of motif under option 3. Then go to folder IMT03 (still in the data folder) and add the characters names into that select.def file instead of the one in folder IMT04.

to open the Mugen file (CFG), use notepad.

MrOmega (author)2014-09-13

I found a fix to get your chars to show. instead of edtiingt the slect.def in ITM04 do it in ITMO3, is that does not work, edit it in ITM02. do all the same steps just igrone the ITM04.

Timothyjbushey (author)MrOmega2015-03-04

or just go into the data folder and open the mugen (CFG file) file with notepad and choose the 70 character motif
under the Select Screen section. To do this make sure there is a
; in front of the the word motif in option 1,2 & 3 and remove the ; in front of the
one under option 4 and then make sure you added characters to the
select.def in the right folder (this one being 004). If you want more than 70 characters, choose one of the other options in this doc instead and then go into the appropriate folder (the pics show the roster image) and edit that specific Select.def

LoneWulfHD (author)2015-02-28

please help. when i extracted IMT Blue two files (system.sff and VSelect.exe) dont extract. I have tried multiple times. WinRar says it is a VCC error, pls help can play game with files.

try it again or maybe use 7Zip to extract it instead.

JeremyS4 (author)2015-01-28

I do all this, and then I open it, and only the kung fu man shows up! Please help!

Timothyjbushey (author)JeremyS42015-03-04

to get them to show up, make sure you have the right set up, go into the data folder and open mugen (CFG file) with notepad and choose the 70 character motif under the Select Screen section. it will tell you to make sure there is a ; in front of theones you don't want and remove the ; in front of the one you do want and then make sure you added characters to the select.def in the right folder (this one being 004)

jacob.baxter.1840 (author)2015-02-09

Thanks, but my characters won't be in my roster :(

ben.scrannage (author)2014-08-19

My characters aren't showing up on my selection screen, and I followed the tutorial perfectly, what happened?

amriorda (author)2013-04-05

I don't know if I'm stupid, or just technically challenged, but I seem to not have the ability to get the characters to appear on the selection screen. Any help would be great. Thanks.

MatthewK1 (author)amriorda2014-08-08

Same here!

RyGuy176 (author)2013-04-05

Sorry but do to the policy held in place by the MUGEN community, i am not to share a screenpack with characters that I didn't make myself. Making your own is the fastest way

spacepirate04 (author)2013-04-04

could you upload yours complete so i can just download and play it
