melonDSi Git (2019/10/20) is complied. melonDSi is able to boot DS-mode games from the DSi menu. They currently run with the DS-mode BIOSes and backwards-compatible touchscreen mode, but at the 133MHz clock speed and with 16MB of RAM. 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!

melonDSi changelog:
* Merge branch 'melonDSi' of https://github.com/Arisotura/melonDS into melonDSi
* add DSi shit to cmakelists
* * some fixes to SD controller support, make it clear that there is no SD inserted, makes Flipnote work somewhat better
* don't auto-patch firmware touchscreen coordinates, atleast until we find out whether that causes problems in DSi mode
