Official dev builds now have DeSmuME fork with the option to render increase internal resolution. Be warned that this option is very system-intensive.

====Official Implementation====
After the increased internal resolutions were implemented in the X432 fork (originally contributed to main but rejected due to ''creative differences''), as well as in Drastic and even the barebones official Nintendo Virtual Console DS emulator on Wii U, the mainline DeSmuME projects decided to reconsider their ''creative differences'' and include their own implementation of higher internal resolution.
Official dev builds now have the option to render at a higher resolution as well, and filter textures to boot. Overall, it's more hardware intensive than X432R's implementation.
The latest development version of RetroArch DeSmuME core also has an option to increase internal resolution which can be set using '''desmume_internal_resolution''' in Core Options. This option was added in [https://github.com/libretro/desmume/commit/5e430dfbc22f9d54c77f291304a38352ee1e5a63 August 8, 2015 commit]. This is massively CPU-intensive because only SoftRasterizer exists in RetroArch core.
