melonDS Git (2020/01/29) is complied. melonDS is an open source Nintendo DS(NDS) emulator. melonDS is part of a second wave of DS emulators. There are a few other emulator projects that are part of it, which you might have already heard of. Either way, check them out!

melonDS Features:
* almost-complete 2D graphics
* 3D graphics (software renderer) with texturing, alphablending, lighting
* input: keyboard and joystick, touchscreen
* backup memory
* booting from the BIOS
* resizable video output window, preserving aspect ratio of individual screens

melonDS Git Changelog:
* Merge pull request #546 from nadiaholmquist/feature/unix-xdg
* Change the config/data dirs from "melonds" to "melonDS" for consistency.
* Remove redundant desktop file and change desktop/icon file name to net.kuribo64.melonDS, also change melonds to melonDS.
* Tell the user where to place romlist.bin if it can't be found for UNIX non-portable builds.
* Make UNIX builds non-portable by default.
* If all else fails, look for data files (romlist.bin) in the current working direcoty.
* Open with rb instead of r in OpenDataFile to avoid potential problems with Windows.
* Add a UNIX_PORTABLE build option, turning it off makes a build of melonDS suitable for systemwide installation.
