I finally found the composer!

(Sorry if the image is not showing up, it's just my first time trying to show an image to this website. I don't even see a tutorial of how to get one to show up...)
According to Stagger I/Red Hawk's Staff Roll, Seo Jung-Hae was credited in "Sound".
Don't believe me? Go to any Stagger I/Red Hawk video and fast forward to the Staff Roll, and there you'll see what I put up there! (By the way, I just think Seo Jung-Hae is a she.)
Also, Afega used some of Dooyong's songs, because after Dooyong's bankruptcy, their employees moved and work for Afega.
Seo Jung-Hae usually recreates her songs for Dooyong's 1993-1996 games.
This is all I can find! So, if there is any misinformation, tell me which ones I got wrong. (I was memorizing what to say.)
