Changing the resolution can work to subtract or increase the quality of a game and the advantages of this can be that if the game is displayed in low quality by raising the resolution can improve the graphics a little. As well as on the contrary if the game has a lot of resolution and it does not show you well, the screen is small and the game is out of the limits you can place a lower resolution and that adjusts to your requirements.
Steps to modify the mugen resolution
Method 1
- Enter the game folder and look for the folder named “data”.
- Find the file named mugen.cfg
