Flame Zapper Kotsujin version 1.0

[CStarFlare]

I'm a big fan of this PC-98 shmup, but I can't find any information about the supposed original release. The version that's floating around on video sites and the like is Ver. 2 (labeled FINAL on the title screen). Not being a Japanese speaker probably limits my searching, but near as I can tell there's really no videos or information about a version 1 on the net in English or Japanese.

I'm hoping someone here is deep enough into the PC-98 scene to tell me if 1.0 actually exists. Genuinely curious to know what differences there may be.
