Thank you for providing it. I managed to identify every Famicom/NES ROM within the code (sifting through loads of junk data), mainly done by just searching for common .nes file sizes (e.g. 25k, 41k). Games of particular note include the following:

*Three uncommon Inventor hacks: Air Raider, Dream Rapid, and a variant of Rush Hour featuring motorcycles (whereas the prior known version uses cars). The early version of Boat Race mentioned a few posts back is also present here in working order.
*Anger Bird, Khresna, and Upin & Ipin Adventure 3, three hacks which are affiliated with the "Play Vision Portable" systems.
*The 8-bit version of Waixing's Explorer (AFAIK, the last remaining undumped VT02 game in the set), as well as an MMC3-based version of Tank. Unfortunately, both ROMs do not run standalone; I assume this is initialization-related, though I could not determine a fix at a cursory glance.

Some additional technical notes that I found interesting:

*As mentioned in MAME's notes, remnants of what appears to be a Linux system are scattered across the SD card; with the NES ROMs haphazardly thrown in alongside the Linux data.
*Every ROM contains space for an iNES header, though in some cases it is overwritten with other data, presumably used by the VT02 menu system.
*Some of the games are duplicated multiple times across the SD card contents. While some duplicates are merely unaltered ROMs, others seem to be in varying states of removing the games' copyright information.
*All of the games are either NROM or MMC3, without support for CHR-RAM; which is to be expected of a VT02 console, but still a bit jarring given its SD card compatibility. There are quite a few MMC3 conversions on here as a result, including some games that are not commonly converted (e.g. Kero Kero Keroppi 1, Tetsuwan Adam).
*The ROM of Fish War features a Nature Color Game copyright, but it was blanked out via PRG (because of course it was). I did attempt to restore the notice, but it required more guesswork than usual...
*The ROM of Bolt Action is massively overdumped, and inexplicably, appears to have overwritten the data of "Mechanical Invader", a Nice Code game that is almost completely undocumented. The CHR is largely intact, though no portions of the PRG are present.

I have attached the most notable games below. I will likely compile the mapper hacks at a later date; if not a full release of the extracted contents. _{(Also note that with all of that, I still have no idea what "Video Player" was supposed to be...)}

it does not show its presumed built-in games.

Thank you all for the information and help. I don't have full-scale mock-ups for the JungleTac title screens, but I can provide the logos; the Fire Fighter one is seemingly modified from the Fatal Fury logo, for whatever reason.

However, the game itself is just a clone of the famous Flappy Bird.

Only if they use mapper 256 submapper 1. Writing a utility for that purpose would be laborious, too laborious for such a nice purpose. The "wii thingy" that takes .WXN files runs them in an emulator of its own, though (and it has horrible sound quality, from what I have seen), so it's not exactly "running games on original hardware".
