GBE+ (Source)
GB Enhanced+ is a DMG/GBC/GBA emulator and experimental NDS emulator. It is the successor to the original GB Enhanced project with a focus on enhancements and emulating as much of the Game Boy as possible.
GB Enhanced+ (GBE+ for short) aims to be a fully functional Game Boy emulator. The goal is to create a highly portable emulator using C++ and SDL, document the Game Boy's functions through clear code, and add as many enhancements (scaling filters, cheats, custom graphics) as reasonably possible. Additionally GBE+ strives to emulate everything about the Game Boy, including obscure accessories.
Compiling GBE+
The only requirements at this moment are SDL 2.0, OpenGL 3.3 or greater, a C++ compiler, and CMake. Qt (for the GUI) and SDL2_net (for netplay) are optional dependencies. GLEW is a Windows-only mandatory dependency.
