    DeSmuME

    DeSmuME

    DeSmuME is a Nintendo DS emulator

    In this version we have added support for high-resolution 3D rendering. Try the new “GPU Scaling Factor” feature to increase the 3D resolution beyond the native resolution of 256×192 pixels. Also, the Cocoa frontend sees continued radical enhancements and while the Windows frontend sees some new incremental enhancements. DeSmuME is a very CPU demanding app. While many users will see DeSmuME as a toy (and use it as such), it is actually a very sophisticated piece of software with lots of features. Also, DeSmuME focuses more on compatibility and features than on speed. Our philosophy is this: You can always mow some extra lawns or babysit some more rugrats to buy upgrades for your computer; but there's nothing you can do to fix compatibility or gain new features. We take care of our side of things, so you should take care of yours. DeSmuME is mostly CPU intensive and less GPU intensive.

    Zelda 64: Recompiled

    Zelda 64: Recompiled

    Static recompilation of Majora's Mask for PC

    Zelda 64: Recompiled is a specialized recompilation project built on top of N64Recomp, focused on reconstructing The Legend of Zelda: Ocarina of Time and related N64 titles into native, compilable code for modern systems. It takes original game binaries and translates them into structured C code that can be compiled and run without requiring an emulator, enabling more efficient execution and deeper access to the game’s internals. The project is designed to preserve gameplay accuracy while providing opportunities for enhancement, including graphical improvements, performance optimizations, and expanded modding capabilities. By leveraging the N64Recomp framework, it benefits from a standardized approach to static recompilation while tailoring the process to the specific architecture and behavior of Zelda titles.
