Is it true that inmates on death row voiced the characters of the video game Golden Axe?

I keep seeing that in Facebook and Tumblr posts, and I try to look it up but can’t seem to find any “official” word on it. Apparently one of the dwarfs was voiced by an inmate called “The Bloodaliser” or something like that. I always wanted to find out if this was BS or actually true, and if so why the hell would Sega let death row inmates voice characters for a kid’s game?
