Okay so I have recently downloaded a bunch of chars from anime fighting games like BlazBlue, Guilty Gear, Melty Blood etc. So I went and added all of them in my character select (I'm using the LEGACY screenpack): Aside from some portrait resizing here and there, overall it looked perfectly fine to me and I was ready to play. I opened MUGEN: to only see Guilty Gear chars and nothing else. I tried to see if there's just a problem with the portraits for the rest (meaning you could still select them) but no, the game only recognized Guilty Gear chars it seems. I decided to look for answers on the Internet and many of them said to make sure the character's def filename and folder name match, so I checked and almost all of them are. One guy said to not have a folder inside a folder so I did this with one char to test but still nothing. Is there something I'm missing here or am I just dumb ?
