Game Boy startup recording: [Nintendo Game Boy Startup — QuickSounds](https://quicksounds.com/sound/24067/nintendo-game-boy-startup). Sounds by QuickSounds.com. Used as embedded sound under the [QuickSounds Standard License](https://quicksounds.com/page/license-agreement), accessed 2026-10-24. Recording identified by its source; no claim of an independently verified hardware capture. No standalone audio download feature.

Startup logo pixel layout: [Pan Docs — Cartridge Header](https://eldred.fr/pandocs/The_Cartridge_Header.html). Boot sequence is a visual recreation, not firmware emulation. Nintendo and Game Boy names/logo belong to Nintendo. This is an independent interactive study, not an official Nintendo product.

Blocks, Snake, Paddle and gameplay pulse effects are original implementations. They are not commercial Game Boy ROMs or original game soundtracks. No background music is included.

Three.js r180 is included under MIT; see vendor/LICENSE. Hardware reference photographs are not distributed in the public site.

## Game Boy Color geometry references
Nintendo technical specifications: https://www.nintendo.com/de-de/Support/Fruhere-Konsolen/Technische-Daten-619585.html
Gekkio and contributors, Game Boy hardware database (Dandelion CG59430386-0): https://gbhwdb.gekkio.fi/consoles/cgb/
Reference photographs were used for modeling only and are not included in the site. Color startup uses the native-resolution capture credited below; no firmware is executed. Original mini-games are palette-colorized for this exhibit.

Side profile references: original yellow CGB photographed in [Ricardo listing 1310357394](https://www.ricardo.ch/de/a/1310357394/) and original purple/green CGB side photographs from [eBay 145618301357](https://www.ebay.com.au/itm/145618301357) and [eBay 397289255674](https://www.ebay.com.au/itm/397289255674). Used to model the continuous curved rear battery grip, taper and side details; no listing photographs are distributed.

## Dimensional convention
Nintendo's [technical data](https://www.nintendo.com/en-gb/Support/Legacy-system/Technical-data-619585.html) supplies nominal H×W×D: Game Boy148×90×32mm and Color133.5×78×27.4mm; nominal LCDs47×43mm and44×40mm. Models use1scene unit=1cm. Software checks use the assembled, unrotated maximum device envelope including controls and excluding the removable cartridge; Nintendo does not specify this datum convention or manufacturing tolerances. Matching nominal dimensions is not a claim of scan-level or manufacturing accuracy. Cartridge width/height are57×65.5mm; its8.795mm modeled thickness remains approximate because public cartridge references disagree. Detailed case contours and internals remain illustrative.

## Imported ROM emulation
Browser-local Game Boy/Game Boy Color emulation uses [binjgb](https://github.com/binji/binjgb), Copyright (c) 2016 Ben Smith, MIT. Pinned revision16621111ed0ee73bcc45c912a823bcebedcffc0f; unmodified JS/WASM runtime and MIT notice in vendor/binjgb. The Pocket Museum adapter is original. No upstream demo ROMs or firmware are included.
Imported games run from the visitor's browser storage; cartridge labels are original generated designs, with optional title suggestions from ROM headers (not verified cover art). Clock-dependent and special cartridge hardware is unsupported in this release. Startup presentation precedes the emulator's post-boot state. It does not validate or execute Nintendo firmware.


## Original GBC startup frames and marks
The 175 160×144 startup frames come from [Zakhary Kaplan’s frame-by-frame SameBoy capture](https://zakhary.dev/blog/gbc-web-button), [original animation](https://cdn.zakhary.dev/img/share/d3dba7d5.gif). Each frame is preserved without resizing or recoloring in assets/boot/gbc-frames.png. Playback uses 70,224 / 4,194,304 seconds per frame rather than the GIF’s rounded 20ms delay. assets/boot/gbc-frames.json records per-frame RGB hashes. The capture contains Nintendo’s original startup artwork; the author’s explicit CC0 statement applies to his finished 88×31 button, not a blanket license to Nintendo artwork. No boot ROM is included.

GBC chime: generated through the pinned binjgb APU from the documented register settings (NR11=0x80, NR12=0xf3, NR50=0x77, NR51=0xf3; frequency/trigger 0x783 then 0x7c1 four frames later). Timing follows [drhelius’s annotated CGB boot disassembly](https://gist.github.com/drhelius/6063265): first trigger after 82 frame periods; second after 86. This is an emulated digital chime, not a recording of a particular console’s analog speaker. The captured visual sequence is pixel-identical to the cited reference; browser display cadence and analog LCD/speaker behavior are not claimed hardware-exact.

Physical shell/cartridge marks use Nintendo vector artwork from Wikimedia Commons: [Gameboy logo](https://commons.wikimedia.org/wiki/File:Gameboy_logo.svg), [Game Boy Color logo](https://commons.wikimedia.org/wiki/File:Game_Boy_Color_logo.svg), [Nintendo black logo](https://commons.wikimedia.org/wiki/File:Nintendo_black_logo.svg), classified there as PD-textlogo. Marks are cropped, arranged and tinted to fit the modeled shell, preserving their vector letter shapes. Nintendo’s marks identify the historical devices; Pocket Museum is unofficial.

## Cartridge photo catalog
32 curated original cartridge photographs from the [Game Boy hardware database](https://gbhwdb.gekkio.fi/cartridges/gb.html) and its [Color catalog](https://gbhwdb.gekkio.fi/cartridges/gbc.html). Individual photographers, source editions, original photos, verified ROM hash sources and crop coordinates are recorded in [catalog.json](./assets/cartridges/catalog.json). Resized photos and cropped labels are CC BY-SA 4.0; see [photo credits and license](./assets/cartridges/LICENSE.md). The collection UI links each displayed photograph to its contributor/source. Matching ROM bytes unlock representative art, not proof of a physical label edition. No game files are included.


## iPod nano — first generation (2005)
Original procedural model and original menu approximation, with local user-selected audio only. No Apple firmware, music or reference photographs are distributed. White 4 GB A1137 identity, Click Wheel, flash storage and 30-pin connection are based on [Apple's 2005 announcement](https://www.apple.com/newsroom/2005/09/07Apple-Introduces-iPod-nano/) and [Apple's model-identification reference](https://support.apple.com/en-us/103823). Exterior/service reference: [iFixit first-generation nano guides](https://www.ifixit.com/Device/iPod_Nano_1st_Generation). Approximately 89×40×6.9 mm is a reconstructed enclosure reference, not calibrated CAD; contours, labels and ports are illustrative. The collection thumbnail is rendered from this site's model.
