Dualis is a NDS emulator for Windows. it is primarily written in C++ and x86 assembly. it is a fairly rudimentary emulator and lacks an awful lot of functionality and has no compatibility with any commercially available game.
Alongside this it also does not offer any real extensive emulation of the NDS’s features, lacking any support for the ARM7 processor at all.
Dualis is primarily for homebrew only, as it is unable to successfully run any NDS game dump. We recommend using other emulators such as DeSumME or NO$GBA, they are much more complete emulators for both homebrew purposes and ROM development purposes.
