Oh, I tried to pay attention but at the end I haven't read correctly. I saw "Geisha" instead of "Gelsha", and I didn't see that Yu-giri's url was incomplete, I was looking for "Sanjose". Nevermind... I found about 30 pages too. Let's have a quick calculation : 10 results per page or so 300 links. If we consider geocities.jp was popular during 10 years, we get 30 blogs per year. It seems plausible, does it ? According to what you say, there is no way for you not to found what you're looking for, except if the site you are visiting does not contain the word "mugen". The chances are low, I think you've already done everything (hats off to your work). By the way, do you voluntarily avoid referencing links that have no "important" MUGEN resources (such as tutorial, home made bgm / stages, sites rating ...) ? E.g. :
  • sky.geocities.jp/haitakanomori/
  • www .geocities.jp/devilgenemugen2010/mugentutorial/installingexcharacters.html
  • www .geocities.jp/kofskurukaga/dairi.html3rd.geocities.jp/rorilltan/list1.html
  • 3rd.geocities.jp/rorilltan/list1.html
