The Coolboy RS-97 is a handheld console released by Anbernic. It is nearly identical in appearance to the Revo K101 Plus, but runs on entirely different hardware. It also goes under the name K101 Pro (to seem like the Revo K101).
This system is one of several bootleg consoles to have been sold by the rapper Souljaboy on his (now defunct) SouljaWatch website, rebranded as the SouljaGame Console. Due to the majority of systems featuring pirated Nintendo software built-in, Nintendo sent a cease-and-desist to Souljaboy around New Years Eve 2018, leading to all of the SouljaGame listings being taken down.
The Coolboy RS-97 looks exactly like the Revo K101 Plus, save for the lack of the Revo logo under the screen. Like the Revo K101, it has a GBA cartridge slot on the bottom, but it doesn't actually play GBA games. It uses a flashcart that only works for the Retro Game, which can be removed. It charges with a micro USB.
It has the ability to run NES, Game Boy, Game Boy Color, SNES, Neo Geo, and Game Boy Advance games. It can crash randomly. When it does this, the reset button doesn't work, so the user will have to open the battery case, then remove and put back the battery.
