Headless Ninja Volley (Master System) - licence ================================================================ Headless Ninja Volley is a homebrew game for the Sega Master System by Haroldo O. Pinheiro (haroldoop / haroldo-ok). Licence: the Unlicense (public domain dedication, any use including commercial). The licence is declared in the "Software licence" field of the game's page on SMS Power! (https://www.smspower.org/Homebrew/HeadlessNinjaVolley-SMS), where the author published the game; the package itself carries no licence file. The text of that page, as read on 2026-11-11, is reproduced below, followed by the standard text of the Unlicense. What this site serves: "Headless Ninja Volley v0.9.sms" from HeadlessNinjaVolley-SMS-0.9.zip, published by the author on SMS Power!, running in the Gearsystem emulator. The ROM file in the package is 12,453 bytes long; we fill it up to 16 KiB with 0xFF bytes (as the unused part of a cartridge chip would read) because the emulator only opens ROM files in whole kilobytes. No byte of the game changes; the script that does it (build-headless-ninja-volley.sh) is hosted with the source. The package includes the author's source code (src.zip, C for the z88dk compiler, with the graphics data); the game has no music. The original package is hosted next to the ROM and linked from the game page. ---------------------------------------------------------------- Game page on SMS Power!

Pinheiro [email protected] The premise of the game is pretty simple: At the beginning, the game will show a menu where you can choose whether you'll play against a friend or against the computer, as well as the color palette. Use arrows to select, and any button to start the game. Once inside the actual game, left and right arrows move your ninja, while any button jumps. You can do an off-wall jump, too, by pressing jump while moving against a wall. Try to push the ball to the opponent's field, while trying to stop it from bouncing twice on your side. The game ends when someone scores 15 points. ---------------------------------------------------------------- Readme of the package (Readme.txt) ---------------------------------------------------------------- Headless Ninja Volley v0.9 by Haroldo O.
