Emulating the Nintendo DS: Part 1

The author shares their decision to develop a Nintendo DS emulator, motivated by dissatisfaction with existing options like Desmume, especially regarding graphical fidelity. Having gained experience by emulating older handhelds like the Game Boy series, they view the NDS as their ultimate challenge due to its dual ARM processors, dual screens (with a touchscreen), and advanced hardware features like 3D rendering and enhanced sound capabilities. The NDS architecture involves an ARM9 and ARM7 CPU, each handling specific tasks, alongside substantial graphical and audio improvements over its predecessor, the GBA. This article serves as an introduction to the complexity of the system and the beginning of the author's ambitious emulation project.
