Modern handheld with Gamezone II games?

[forgotusername]

I came across a YouTube video showing an odd emulation-based handheld dubbed the "Great Boy". For whatever reason, it includes four of the "Gamezone II"-affiliated arcade ports (Scramble, Moon Cresta, Missile Command, and Frogger); which almost never surface on other plug & plays. Judging by an Amazon review of the console with screenshots (https://www.amazon.com/gp/customer-reviews/R140J8JZN7UT02), it dates back to at least 2021; whereas the Gamezone II was only dumped online in late 2023.

The Great Boy only includes 20 games total (despite the Amazon page claiming 1015 games, though it may be that the others are hidden on a microSD); with around half of them being common Nice Code derivatives. However, there are six additional games which I do not recognize at all: Falling Fruit, Lost Home, Match, Pong, Sky Up, and Tic Tac Toe. Pong is the only one to feature a title screen, and appears to be NES-based; I can't tell if the other games are based on Famicom/NES hardware or something customized for the handheld.

I felt this system was worth noting here due to the obscurity of the games included, and it could be something worth looking into further. Here is the YouTube video of the console (note that it's recorded by a young child): https://www.youtube.com/watch?v=QS5HI-kNqsQ

Perhaps I could purchase a unit and take a look at the microSD.

Just realized that the only surfacing video is a low quality one hahaha

Okay, forgotusername, my unit arrived. Oddly it's in a "GB-10X" packaging even though that's of a different Sunplus system. What did you want to look for in particular?

The thing to check for, I believe, is to see if the console loads an additional game menu that appears when no microSD card is inserted. I'm guessing this is how the 20-in-1 menu (with Gamezone II ports etc.) is accessed. It's possible the ROMs are also mirrored on the microSD contents, so that's worth checking too; though in how it's demonstrated, I'm guessing the 20-in-1 is built into the actual console memory.

You're correct. The 20 games are flashed on the system itself (would need a hardware dump, which I can't do), and a different menu shows up when the microSD is inserted.

i know that there is/was (not entirely sure) a group called Project Plug & Play who might be able to dump it
