Updates

What has changed on MasteryHub.

26 October 2026

1.2.0

  • Mosaic: downloads no longer need every icon scrolled into view first. The button loads the artwork itself and counts it in. Big boards export more reliably, on iPhone the download opens the share sheet so it can be saved to Photos, and an export that takes a while offers a Save button when it is ready.
  • Mosaic: choose the download quality: Standard (PNG) or Small (JPG), a lighter file for posting.
  • Mosaic: presets. Default, or Icon Wall: just the box art, edge to edge, with the columns set to make a wall taller than it is wide.
  • Mosaic: show each tile's mastery number (#N, counted from your first mastery).
  • Mosaic: choose the order of the text under each tile, put fields on the same line, and change the gap between them, or show the info on the icon itself.
  • Mosaic: removing games works on phones. Turning on Remove games puts a × over every tile to tap, instead of one that only appeared on hover. Dragging pauses while it is on.
  • Mosaic: the ramasteryhub.com mark now sits in the empty space at the end of the last row when there is room.
  • Mosaic: new default look. Bigger icons with the mastery number, title and RetroRatio printed on the icon, and auto column count on.
  • RetroRatio: show each game's RetroRatio (its RetroPoints divided by its points, RetroAchievements' measure of how rare a mastery is) on the mosaic tiles and on the Mastery Card. The first time a big board is shown it can take a few minutes to fill in. A notice above the board says when ratios are still loading, paused, or could not be loaded.
  • Mastery Card: presets. Default, or Wide: a landscape card with the box art, the game, your mastery number and stat boxes, on a background tinted from the box art.
  • Mastery Card: Tint background from icon, a setting that fades the box art's colour into the card's background. On by default in Wide.
  • Mastery Card: no more ramasteryhub.com mark on the card.
  • The home page's Mastery Mosaic and Mastery Card buttons now sit side by side.
  • The footer now sits at the end of the page instead of staying on screen.
  • The site is dark-only now; the light theme and its toggle are gone.
  • FAQ: why MasteryHub is free and ad-free, and where to send support if you want to (RetroAchievements first).

1.1.0

  • Mosaic: custom order — drag tiles on the board to arrange them by hand, instead of by date or title.
  • Mosaic: Hide / Filter masteries — remove individual games from the board, or narrow it to games matching a text search like "Hack" or "Mario".
  • Mosaic: the profile header's mastery count can show either every game RetroAchievements has on record, or just the games currently on the board.
  • Fixed the Mastery Card's game dropdown showing unreadable light-on-white text when the site is in dark mode.

Initial release

  • Mastery Mosaic — every game a RetroAchievements username has mastered, laid out as a grid of box art with a settings panel for the profile header, game titles, platform, mastery dates, colours, layout and sorting.
  • Mastery Card — a single-game card built around one mastery, with its own header, icon glow, platform, date and card styling, and a dropdown to switch which mastery it shows.
