Install this emulator's files

With RetroPie: the installer finds RetroPie and its BIOS folder, then downloads only the files Super Mario War reads there and checks each one.

On the device

Open a terminal on the device. Or connect from a computer with SSH, a terminal over the network. Paste the line. Press Enter.

Terminal

curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --emulator supermariowar

Technical notes

The open source continuation of the Super Mario War fan game. The code and the game data live in two repositories: the engine reads graphics, sounds, music, maps, worlds and tours from a data directory, ./data beside the executable unless --datadir names another. A graphics or sound file missing from the selected pack falls back to the Classic pack, and missing menu fonts or start graphics stop the game at its splash screen. ref: src/common/global.cpp:24-29, src/smw/main.cpp:295-296, src/common/path.cpp:148-206, src/smw/GSSplashScreen.cpp:53-80

EmuELEC builds this revision with a patch moving the configuration to /emuelec/configs/smw. Its run_smw.sh fetches mmatyas/supermariowar-data at da13a367 into /storage/roms/ports/smw/data on first start, when worlds/Big JM_Mixed River.txt is absent, and passes that directory as --datadir. ref: EmuELEC packages/sx05re/emuelec-ports/supermariowar/package.mk:4-5, EmuELEC packages/sx05re/emuelec-ports/supermariowar/scripts/run_smw.sh:10-14,25-43
