Obsessively combing the net for more info and hopefully videos, but so far I'm finding absolutely nothing besides Sam's article and pics. :D
Eh, might as well post an updated version of the game list with the official names for the games in Sam's article. Names in bold are official ones.
Edit: Updated the list with game names from the Twitch video
1) Fragile Platforms
(Ice Climbers with a Samus-like main character).
2) Sub Hunt
(multiscrolling fish shooter).
5) Adventures of Lolo / Sokoban
6) Caramel Caramel
(Gradius). It shows two sections but it's the same game.
7) Pocky and Rocky
(UFO with boomerangs).
10) Fist Hell
(Kunio Kun / Renegade / Double Dragon).
11) Blaster Master
12) Son Son
14) Hyper Contender
(Towerfall / Smash Bros).
15) Party King
16) Onion Delivery
(GTA / Retro City Rampage).
(Mother / Earthbound?).
20) Seaside Drive
(Silkworm, horizontal car shooter).
21) Kick Club
22) Dino Defense
(prehistoric tower defense).
24) Blaster Master
(side view sections; another UFO cameo).
25) Sacrifice II
Two by two split screen:
(Knight crushed by falling ceiling)
1-2) UFO Racers

2-2) ??? (Walrus diver)
Four by four split screen:
1-1 a) Star Waspir
1-1 b) Metal Storm.
1-2) Afterburner / Fantasy Zone (again with the UFO :) ).
1-3) Final Fantasy (!).
1-4) DOTA? (seems to be a two player game where you spawn enemies to send against the other player).
2-1 a) Paint Racer
(Splatoon, 2p versus, paint the tiles).
2-1 b) Orbient? (gravity / orbit game).
2-2) ??? (grid strategy game with castles).

3-3 b) Sacrifice II
3-4) Rogue? (green grid).
4-1 a) Disc Lords
(Tin Pin Slammer).
4-1 b) Super Mario Bros 2.
4-2) Quibble Race
(two menus, races / loan, same game?)
4-3) Dungeon Master / Eye of the Beholder
4-4) ??? (no clue what's going on there :D).
I can't locate Camouflaged or Sacrifice I from Sam's writeup, nor Diabolika; also, the following are game names from the Twitch video that I can't conclusively pin on any game:
- Bug Hunter
- Ant War
- Campanella / Campanella 2 (these are the UFO games, but which one is which?)
- Elfazar's Hat
- UFO VR (this is probably 1-2 from the 4x4 split)
As an aside, I really love that each game's name is so descriptive and straightforward, that's going to be a huge help when trying to remember which game is which.
