Mostly on where they come from; I have never seen that version of I.Q. Champion, for example.To the best of my memory, they were from the following MAME ROMs:
*pocket brick = "Virtual Football (with 3 bonus games)" [vfootbal]
*cute kids, iq champion, submarine bomb = "unknown VT02 based 25-in-1 handheld" [vt25in1]
*cookies labyrinth, golder = "Cyber Arcade Pocket (JL1895)" [lxcap]
*twin cards = "5 Bonus Games" [5bonus]
*apple chess vt03 = "Zudu-go / 2udu-go" [zudugo]
*solitaire (one-card draw) = "My Arcade Plug And Play 220 Game Retro Controller (DGUN-2959)" [dgun2959]
"Brave Boy" came from an otherwise-generic multicart released on LIBG, I don't recall the name of it.

I am not familiar with them, so I cannot say without having seen them.I have five of them on hand. Antiquarium, Move Box, and Plane are just the current ProjectPNP copies with their CHR banks removed, as the code is additionally read off of the PRG; the common copies of Mine and Goblet Tower are fully converted to solely read off of CHR. Note that Goblet Tower is/was a VT01 copy that I altered to use its "normal" colors.
My theory is that the earliest Nice Code games used this CHR-less coding, as multiple additional titles seem to have zeroed-out graphics data within their PRG (Music Moment, Balloon Shoot, Toy Bricks, etc). AFAIK the general VT02/03 architecture isn't compatible with files like this (though UM6578 is), which presumably led to the games being converted to use CHR later on.
