So I was reading up on some old EGMs when I came across this bit in the reader section of the magazine. I went and checked SEGA Retro if there was any info on it but couldn't find anything under either name. I started doing some searching a couple of minutes ago and found these flyers at the The Arcade Flyer Archive. Apparently these machines were around the good old 97 by SEGA Pinball Inc. I'm still looking up for more info on this.
