I don't know anything about Ikemen Go because I've never bothered with trying it, but it is possible to use hardware scaling in Mugen 1.1 OpenGL mode. This can regain some (not all) image quality. How you want to do this exactly will depend on your current screenpack and monitor, so I will only provide an example based on what I do. Your results will vary.
Step 1: Configure Mugen for your screenpack
In my case, I use a 640x480 screenpack. Mugen can be run in whole multiples of the screenpack size, so I choose x3.
Code:
[config]
GameWidth = 1920
GameHeight = 1440
Step 2: Hardware scaling
Now I am going to scale that down to my monitor size (1920x1200). Since my screenpack is 4:3, this will result in a 1920x1200 window with vertical black bars on the side (1600x1200). There are some settings further in the video section for managing that behavior if desired.
Code:
[video]
Width = 1920
Height = 1200
Result? I have way more pixels available than normal, and I'm using the video card to hide the evidence when I scale something. That means I can scale any of my characters to an appropriate size and they won't look ugly. Pretty cool trick.
