I still haven't gotten a full extraction (for the record, I have no clue how to use binwalk, I just converted the .bin to .zip and extracted it...), but I found a full list of games somewhere in the file. From there, I ripped any games that sounded unique, and found two new ones; "SpiderMan3" and "TheLegendOfKhresna".
From what I see in the list, "Crash", "Higame1999SuperDonk", "JungleExplore", "Link", and the Genesis-based "hangman" are most likely undumped ones as well. But my file cuts off at LittleMagic (which I guess is why it ran properly as it?) so I can't access those. If anyone wants to look and has the technical know-how, those are the ones worth checking.
Downloads attached of the two roms + full gamelist.
EDIT: Forgot to mention that Hangman may be the pirate original released in 2007 by, drumroll...AtGames. Combined with the identical emulator(s), that could prove AtGames has ties to the bootleg market - which was already quite obvious, but not to this extent...
