Seeking help for a research project. Anyone have access to Block Challenger/ Block Perfect/ Lionex?

I'm assisting with a project about the history of Sunsoft, and they have a handful of games that haven't been ripped and have very little existing documentation (that we can find).

Their first two video games ever are said to be the following:
- GT Block Challenger / Block Challenger / G T Block Charenger
- GT Block Perfect / Block Perfect

These were released sometime around October 1978, and were produced by Gifu TOKKI. They are reportedly clones of Breakout.

Then there's also a Nintendo Vs game called:
-Lionex

All we have is a short clip on youtube, and a magazine ad. I find this particularly interesting because it's essentially a lost Famicom/NES game by Sunsoft. Edit: To clarify, it's unreleased, and something in the ballpark of 2 people are known to have cabinets. The ROM has been ripped, but it's not publicly available-

So I realize that Lionex in particular is a total long shot.

If anyone knows anyone who has access to these machines and is able to provide more pictures and video of them, that would be incredible.
