Seems a new version of the GBA, DS, DSi and potentially one day 3ds emulator known as no$gba dropped.
For those unfamiliar it is an emulator that started out just doing the GBA but over the years added those other things (also PS1 PocketStation as it was similar hardware). Its debugger (useful for homebrew authors, ROM hackers, commercial developers, cheat makers and more besides) is one of the best going and its accuracy as an emulator is also right up there.
The hardware documentation it...
No$gba 25 Apr 2020 - version 3.01
