That doesn't really explain anything about Zook Hero, given that God Medicine is an RPG, heh. But there is something sort of related that always struck me as interesting.
In all of VFame's English-language RPGs on GBC, the font used for dialogue is not from PC Paint, as is the usual for that company. Instead, the dialogue font is from Survival Kids...which is also by Konami.
So did they actually base their RPG engine on Konami's or something?
