Retro Station Pocket System GB-50
Another VT-series console supporting MicroSD cards, similar to BL-826A, with larger memory for loading ROMs. Built-in it has 150 Nice Code VT03 and NES games, and comes stock with an SD card containing 500+ NES games.
Uses a GBA SP battery & charges over MicroUSB.
Although my unit has a 2019 seal, it's been stuck over another 2019 seal which was broken, so presumably it had to be opened for some reason before sale.
