Due to an occurrence I like to call "I woke up at 5 AM and I could never go back to sleep", I did a deeper analysis on this thing. Since Nintendulator now supports the VT369 format, I can view that format of games easier; and there is...a lot to unpack here. So much that I really can't even document all of it. But I thought I'd mention what's there, to the best of my ability.
Basically, it seems that every Cube Tech VT369 hack is in here. That includes ones like the Donkey Kong Jr./Jr. Math hacks, which were not on the My Arcade console, but appeared on some 230/240-in-1s from other manufacturers. But more interestingly, there are at least eight hacks that have appeared on some of the plug & plays (in 2x resolution), but I don't think any mini arcades (which are 1x resolution) with them have surfaced. Those eight hacks are of:
*Bokosuka Wars (seems broken...)
*Glommy Chess
*Hon Shougi
*Magic Bubble (Nice Code Tetris)
*Ms. Pac-Man (Tengen)
*Pac-Man
*Tetris (Tengen)
*Xiao Ma Li
There are multiple Cube Technology original games that go unused as well, including:
*Cube (puzzle game)
*Love's Arrow (shooting game, hit both hearts at once)
*Unknown table tennis game
*Unknown puzzle game, Zuma-ish
*Unknown music/rhythm game
*Unknown karate game, smash the objects
I was only able to rip games that were 256K or 512K in size; meaning there are possibly more unused, larger-sized ones that I couldn't access. But I'll save trying to find those for another sleepless night; for now, here are the ROMs of every game listed above.
