Seventh Cross Evolution, All Evolutions (Dreamcast, 1998)

It was a pain in the ass, but I did it. I got all the possible parts in 7th Cross Evolution. I would NOT recommend this to anyone, especially on original hardware. It would likely take WEEKS if not MONTHS of trial and error. And 7th Cross isn't a particularly fun game to play for that long.
Creature designs are pretty cool, tho.
