• OSD/OS is developed by mehmet raif tasdemir (darkBLACK), github.com/mehmetraif.
• It is a modified version of 240-MP by Anthony Caccese and its contributors: the app it all started from.
• OSD/OS's changes to 240-MP were written with Claude Code, Anthropic's coding agent.
• The OSD/OS logo, the channel logo over the picture and the boot screen's cassette were made with ChatGPT, OpenAI's assistant.
• 240-MP was made the same way. In Anthony's words, from its README: "Because this is a hobby project (and a fairly niche use case), I am using Claude Code to build a large part of the backend C++ code and structure the modules. If you have concerns with that, I am glad to talk through it. Also, please feel free to fork this repo, update any aspects and tailor things to your own use case; that's why the source is fully open and available."
• The VCR OSD Mono font was created by Riciery Santos Leal (a.k.a. mrmanet) https://www.dafont.com/vcr-osd-mono.font
• The Unifont font (used as a fallback for characters that VCR OSD Mono does not cover) is GNU Unifont by Roman Czyborra, Paul Hardy, et al., licensed under the SIL Open Font License v1.1. https://unifoundry.com/unifont/ — license text: assets/fonts/LICENSE-unifont.txt
• Thank you to Plex, Jellyfin, Emby and Open-Meteo for providing open and free apis to enable building modules for each, and to TMDB, JustWatch and Wikidata for the catalogues behind Netflix and Prime Video. This product uses the TMDB API but is not endorsed or certified by TMDB. Weather data by Open-Meteo.com, under CC BY 4.0.
• Thank you to the MPV team for a simple, extensible and cross platform media player, and to Qt, SDL, FFmpeg, yt-dlp, Deno, Chromium and MAME, which OSD/OS stands on.
• The High Scores module reads MAME's high score files with openhi2txt, by inigomonyota (GPL-3.0), which parses XML with RapidXML, by Marcin Kalicinski (Boost Software License or MIT), and through hi2txt's game definitions (many of them from HiToText), by GreatStone and their contributors (hi2txt-xml, GPL-2.0). MAME's hiscore plugin, which keeps most of those tables, was written by borgar, and its hiscore.dat is maintained by Leezer.
• The Arcade module's pictures and data come from RetroAchievements (achievements, leaderboards and hardcore play, and the games' pictures and the achievements' badges, read through its Web API with your own account; OSD/OS is not affiliated with RetroAchievements), from progetto-SNAPS by AntoPISA (the Snapshots and Titles packs and catver.ini; its screenshots are free to use under fair use, their copyright held by the companies that developed and published the games), scraping using Arcade Database by motoschifo (whose service gives progetto-SNAPS' pictures of a set on request; names and images under fair use, all copyrights and trademarks their holders'), and from libretro's lobby and relay servers for online play. Thank you to all of them.
• Thank you to Raspberry Pi for the boards, and for Raspberry Pi OS and pi-gen, which the OSD/OS image is built with, and to Debian, which Raspberry Pi OS is based on. What the image carries, under which licences, is in os/NOTICE.
• And from 240-MP's README, Anthony's thanks to the Raspberry Pi Foundation "for helping me fill a drawer with SBCs to tinker with and inspire fun ideas like this project ❤️"

240-MP

OSD/OS grew out of 240-MP, Anthony Caccese's VCR-style frontend for CRTs. Its own pictures show where it started, before OSD/OS's menus:

• Photos of 240-MP on a CRT: the picture that headed its README, module selection, an item's page, the resume option, playback and settings.
• Its video overview, on YouTube: https://youtu.be/r-gylGDoELY
