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):
https://www.youtube.com/watch?v=Gb6IhU_0C0Ai 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.
