I am all over these. Honestly, if it weren't for Mugen, I would have never played or even heard of these.
Question: did 9 convert all of Melty Blood's roster?? Or there some missing that other authors/contributors have made?? I'm hoping 9 did them all as they are all solid characters in my opinion. 
He has converted over the 75% of the roster. He hasn't made Mech-Hisui, Normal Arcueid, Normal Akiha, Normal Ciel, Archetype Earth, Executioner Ciel, the Neco-Arcs, Ryougi Shiki (his friends Young Kirei and Take K. did, though, but she has a couple of missing things).
Another question: What exactly does the .CFG text file... configure?? All of the text looks like gobbeldygook due to it being a different language, E.G. odd characters. Any insight would be appreciated. 
And it's great to have these in my Mugen once again. I had them a long time ago in my old WinMugen days. Come to think of it, I still have those older versions on my Desktop!! And I'd also like to add that 9's and Rajaa's Melty Blood Characters are a real treat. All of these are simply fantastic and I love the way they play.
