I understand. I'll search for official material with his name written in kanji.
I've been watching some staff rolls from SNK arcade games and I find that KONNY appeared in a lot of them instead of KENNY, including Garou Densetsu/Fatal Fury. Some Japan Wikipedia entries like
Garou Densetsu credit KONNY (not KENNY) as 西田和弘 again. If KONNY is actually KENNY, maybe is more easy to find kanji info from Garou Densetsu, and VGMdb could merge KONNY and KENNY profile pages.
