Why are the only games listed the arcade game, ASB, EOH, and that Part 1 game?

Where's the Part 5 game? https://en.wikipedia.org/wiki/GioGio%27s_Bizarre_Adventure

I played through it, it's pretty good. Haven't seen any runs of it though.

On a side-note, where are the Eyes of Heaven runs? They're aren't any, and that disappoints me.
