Technical notes

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. ref: KNULLI package/emulators/advanced_drastic/advanced_drastic.mk:7-14, KNULLI package/system/knulli-configgen/configgen/configgen/generators/advanced_drastic/advanced_drasticGenerator.py:30-50,156-158

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. ref: drastic r2.5.2.0 0x131018-0x1310f8, drastic r2.5.2.0 0x12fa18, drastic r2.5.2.0 0x12fce0, drastic r2.5.2.0 0x132128-0x132260, drastic r2.5.2.0 0x132a90-0x132aa8, drastic r2.5.2.0 0x1359b8
