GB OPERATOR is a slot that allows you to enjoy the Game Boy cartridge introduced by Epilogue on PC. It can be used by connecting it externally to a PC, and it has an emulator built-in while in use, so it is possible to save it while playing or restart it from the same location.
The core emulator is mGBA, which allows you to play Game Boy Color and Game Boy Advanced. When you plug in a pocket camera, it also extracts photo data or supports cheats. You can also create your own games using a program called GB Studio. In addition, illegal cartridges can be identified at once, which can be used to identify fakes.
It is priced at $49.99 and will ship worldwide in August. You can enjoy it on Mac or Linux, so you can use it regardless of the operating system. Related information can be found here.
