This last game was originally released on DSI. It's the first game in the series, it's sequel (Go! Go! Kokopolo 3D: Space Recipe for Disaster) is already listed on the site as "Go! Go! Kokopolo 3D". Both of these games recently received physical prints from Limited Run Games, so (of course) I simply had to get them! Anyways, the info is below for the first game:

@GoldenSpork and @Guildofgamers - Those have all been added!

@kw4s - I split out the first Valis game since it appears as though the Genesis / PC Engine CD versions were different from the original MSX release (which was ported to a few other platforms). It doesn't seem as though the Genesis and PCE-CD should be split out, so that means the same game will be in both collections. Is that what you're thinking as well?

@moho_00 seems about right, yeah. According to this review https://www.youtube.com/watch?v=DKDtH56t6ag&t=169s there are some differences but not "totally new game" kind of differences. Also, the review mentioned that the MSX version was also included in the second collection (which was not mentioned on the LRG page) I quickly checked nintendo.co.jp, and yep - the second collection includes 4 titles not 3 as I previously said
unfortunately I don't have my copy yet, so I cannot confirm if it is in the western release of the collection but it certainly is the part of Collection II that is on the JP eshop: - https://store-jp.nintendo.com/list/software/70010000053987.html
So:
Valis: The Fantasm Soldier Collection - Valis The Fantasm Soldier, Valis II, Valis III
Valis: The Fantasm Soldier Collection II - Valis IV, Syd of Valis, Valis: The Fantasm Soldier, Valis: The Fantasm Soldier (MSX)
