How to fix MUGEN 1.1 Error

Are you having an error when opening MUGEN version 1.1? Calm down. Chances are you can fix it one way or another. Continue reading to find out how...

Error no. 1 - Resolution Error

Clipboard tail:
------------------------------------------
M.U.G.E.N ver 1.10 (2012.08.31) status log
------------------------------------------

Initializing graphics...gameCoord 1280x720...render mode 2_20...trying 1280x720x32 mode 0x0...failed.


If you are getting this error it means that your computer resolution is lower than 1280x720 and cannot handle this resolution. This can be easily fixed by lowering the MUGEN resolution. Open the data folder and edit the mugen.cfg with notepad and under "CONFIG: change the "GameWidth" and "GameHeight" to whatever you want.

;Game native width and height.
 ;Recommended settings are:
 ;  640x480   Standard definition 4:3
 ; 1280x720   High definition 16:9
 ; 1920x1080  Full HD 16:9
GameWidth = 800
GameHeight = 508

Error no. 2 - OpenGL Problem
If you are getting an Error that reads OpenGL, then you are a bit unlucky. There are a few steps to take in order to diagnose what's causing the problem and fixing it.

Step 1 - Check if your Graphics Card supports OpenGL 2.0 or higher
New MUGEN 1.1 features require OpenGL 2.0 to work. Use this tool to check if your Graphics Card supports it:

Step 2 - Changing rendering method
This will fix your problem even if your computer doesn't support OpenGL, but new MUGEN 1.1 features will not work and if you try to implement .png files into it, they will just appear black. Also some stages that are using .png files will appear black as well, but the engine will work properly if you use .pcx files.
Open mugen.cfg. that is located inside data folder, with notepad and under "VIDEO" change the following "RenderMode =" from OpenGL to System.
But if your computer supports OpenGL and you want the latest features, then Step 3 is recommended.

Step 3 - Drivers and Windows 8/8.1/10
Update your Graphics Card driver and check if MUGEN 1.1 works for you.
It doesn't? Are you running Windows 8/8.1 or 10? Then it means that you have installed a new Operating System(OS) on an old computer. Sometimes new Operating Systems don't support all the necessary drivers (Especially Windows 10 that is very new). You might find some fixes to this around the internet, but I suggest reverting back to Windows 7. It's what I did on my old laptop and I can assure you that it will work.

I hope this article helped you in solving your problem!

Basically you guys need to go to mugen.cfg and chance the "OpenGL" for DirectX or System

For everyone who is still having trouble, try this:

go to the data folder and open the mugen.cgf folder and find this
--------------------------------------------------------------
[Video]
;Screen rendering mode.
;OpenGL - Experimental OpenGL renderer (recommended)
;System - default SDL rendering mode (e.g. windib in Windows)
;DirectX - DirectX 5 renderer
;System and DirectX modes do not support advanced features
;such as RGB sprites and window resizing.
RenderMode = OpenGL

Change "RenderMode = OpenGL" to "RenderMode = System"

Hope this helps!

I figured it out.
go to you computer files, type Control Panel in the search bar, click Programs, then click Programs and Features, and click Turn Windows Features on or off. Check every box (I'm not sure which one to check specifically so just check them all). Finally, click Ok and update your computer. that should do the trick.

Bro,,,Thanks so much. My problem was about resolution error. Many videos I saw on youtube also with the same thumbnail including my problem.. But I tried them, nothing changed at all.. The YouTubers were only telling to change rendermode from "OpenGL" to "DirectX", another man was showing to change it to " System". But after doing that it was showing a different error. Then I understood that those were just causing another errors instead solving. However, at last, I searched on Google and found your blog, tried it and my problem is solved now.👍
