Kazuhisa Hashimoto, a Konami veteran who worked some of their earliest classics has unfortunately passed away at the reported age of 61.
This was confirmed by Yuji Takenouch on Twitter (An ex-Konami Sound Designer):
Konami also offered the following statement:
While Hashimoto-san will be vastly remembered for the famous Konami code, there's a larger significance to Goemon fans in that Hashimoto-san worked as a Designer on the first entry of the Ganbare Goemon series: Ganbare Goemon! Karakuri Dōchū.
This title brought Goemon to Famicom and MSX where it gained acclaim, planting a seed that would eventually bloom into the popular Ganbare Goemon franchise! Without Hashimoto-san, would this website exist today?
Our thoughts are with Hashimoto-san's family at this time. May we honour his legacy by firing up a copy of Ganbare Goemon! Karakuri Dōchū.
