how does the vt09 emulation work on the gb-60a handheld?

[kelvin donna]

hello there,
recently, i picked up the gb-60a handheld from aliexpress. it was very fascinating to me, when i saw, that it does vt09 games as seen in this video (jump to 24:06):

i wonder if other vt games would work on it as well, since nes games show up like this (see picture)
this one may be a hint to the nes emulator being an emuvt.
