GarboDev, a new GBA emulator, is released

GarboDev is a new, open source GBA emulator written in C# 2.0, so requires Microsoft .NET Framework 2.0 installed to run properly. The author, Gary Linscott, says the compatibility it's near 100%, uses pixel shader (DirectX 9) rendering, plus has debugger capabilities

Pixel Shader rendering? WTF?

OK, this definitely deserves a try.

Pete's OGL2 GPU plugin has a similar feature, as well as MPC with VRM9 mode (Direct3D 9) output and shaders enabled. This is kind of hardware filtering, usable if the videocard supports OGL2/D3D 9
