+  trngaje's package around the closed-source 64-bit Linux DraStic, whose
+  screen output, input and settings menu it replaces through a hooked SDL2
+  build (trngaje/SDL_drastic) and the drastic_layout library. The repository
+  carries the DraStic binary itself, md5 59a7711eff41c640b8861b4d869c747d,
+  which announces "Version r2.5.2.0", together with its system, config,
+  resources and microphone directories, game_database.xml and usrcheat.dat.
+  launch.sh changes to its own directory and runs ./drastic on the content.
+  ref: README.md:1-12, launch.sh:1-9, drastic r2.5.2.0 0x135990
+
+  KNULLI builds this revision, installs the whole tree under
+  /usr/share/advanced_drastic, copies it to
+  /userdata/system/configs/advanced_drastic on first launch or after a board
+  change, then starts launch.sh from there. The copy includes the Nintendo
+  BIOS and firmware images the repository ships, so the platform installs
+  them with the emulator.

+
+  The binary names the same system files as DraStic r2.5.2.2: each BIOS slot
+  takes the Nintendo image, then the free DraStic one ("Can't find Nintendo
+  ARM9 BIOS. Trying free DraStic ARM9 BIOS."), the firmware is
+  nds_firmware.bin alone, a file of the wrong length is refused with "System
+  file %s is the wrong size", and an empty slot ends in "FATAL: Could not load
+  system files." It carries neither the firmware editor's
+  nds_firmware_modified.bin nor game_database_user.xml. The root also serves
+  game_database.xml, usrcheat.dat, microphone/<game>.wav then
+  microphone/microphone.wav, drastic_dldi.img for homebrew and the
+  drastic_logo_<n>.raw splash.
