DeSmuME

Accuracy

Performance

Features

DeSmuME is an open-source Nintendo DS emulator and is among the most accurate. It sports tools designed for hackers, speedrunners, youtubers, and casual gamers (use Dev-builds). Homebrew programs are supported and can even be debugged through GDB. It can be run from the command line directly or as a graphical program and it even allows for increasing internal resolution. It is also available as a libretro core for RetroArch.


DeSmuME X432r is a modified version that has filters, OpenGL video setting, 3D emulation, rotate screen, up scale resultions and much more but requires a higher end PC and hasnt't been updated since 2015.

0.8 -> 0.9

There have been so many changes that this list can hardly be considered complete.

For this release, we have formatted the list into a high level overview of big changes and bad bugs relative to the previous release. Hopefully what you're interested in.

This list does not include items which are solely performance boosts, for let us just say that virtually every system has been speeded up.

 

* The savestate system is totally changed and incompatible with old savestates.

* The 3d system should be considered rewritten.


General/Core:


enh: Convert to c++

enh: Add secure area decryption from ndstool [zeromus]

enh: Change savestate code to support loosely bound chunks and more easily other parts of the emu (GE, GPU).

     The savestate format is changed, but from now on it is in principle more resilient 

     (though it will continue to break as we tinker with the internals) [zeromus]

enh: Added SSE2 optimizations for matrices. Since we now make an SSE2 build, more optimizations can be made. [CrazyMax]

enh: Add a preliminary GUI hud system [CrazyMax,zeromus]

CPU/MMU:


bug: Many fixes in IPC and GE FIFOs. Fixes freezes in NSMB, dsracing, and others. [CrazyMax,luigi__,shash]

     The audible core runs with the host, causing music to slow down but not tear or pitch bend. [zeromus]

Graphics:


- Overhaul 3d:

 . Move entire GE to core emu.

 . Move OpenGL renderer to emu core for optional use by platforms, removing ogl_collector. Now every platform shares the same 3d code.

 . Reorganize 3d code to defer rendering to after 3d vblank. Eliminates tearing, and texturing artifacts. [zeromus]

 . Add optional fragment shading pipeline (more precision) [luigi__]

 . Move lighting model to software instead of using opengl's fixed function model [zeromus]
