Anbernic has started selling the RG503, a small handheld games console with a 4.95-inch OLED display. The Arnbernic RG503 is available in three colours but only 16 GB of storage and 1 GB of RAM. Supposedly, the US$150 is powerful enough to emulate games from many popular consoles, including the Nintendo 64 and PSP.
