GB Enhanced+ vs Gearboy

GB Enhanced+ is a free, open-source emulator for DMG, Game Boy Color, Game Boy Advance and Pokémon Mini systems, available on Windows, Linux and macOS. Nintendo DS emulation is described as experimental. The project focuses on emulating peripherals and less common hardware, with support listed for the Wave Scanner, Wantame Card Scanner, Vaus Controller and WorkBoy. It also supports link-cable emulation, real-time clock features, save states and controller input. Configuration options include joystick haptics, accelerometer input for motion controls and netplay settings for linking emulator instances. The emulator can automatically apply an IPS or UPS patch file when it shares a name with a ROM. PDF and ODT manuals cover operation, netplay, rumble support and motion controls. Building it requires SDL 2.0, OpenGL 3.3 or greater, a C++ compiler and CMake; Windows also requires GLEW. Qt for the GUI and SDL2_net for netplay are optional. It is licensed under GPLv2. Save states from version 1.9 and earlier are incompatible with version 1.10.
