v0.50

New since v0.44:

• PlayStation: PS1 games from Slot/Games/PS1 (.cue/.bin, .chd, .pbp, .iso, .m3u) on a shelf of discs that spin into the slot, games of several discs included.
• Rumble: games that rumble now drive the Brick's motor.
• Favorites (Y) and sorting (SELECT), with play time and a title card for the selected game.
• Brick Pro support: its left stick works as the D-pad, and its stick lights have their own LED row.
• Fonts: HOME → System → Font, with GohuFont included, and room for your own in Slot/Fonts.
• A reworked HOME menu: Emulation, Gameplay, Library, Online and System.
• Faster startup, and Wi-Fi fixes.

INTRODUCING: Slot OS

Slot as its own custom firmware: the Brick boots straight from the SD card into Slot, in under
3 seconds instead of about 9. Otherwise it is the same Slot, with the same games, saves and
settings. Flash slot-os-v0.50-sd-card.img.xz onto a card (it erases the card); the README has
the guide. It keeps itself up to date through HOME → Online → Update.

Dev build

Test build of the latest changes, 25 October 2026. It may have bugs.

v0.44

New since v0.43:

• HOME → Update: update Slot over Wi-Fi. It shows what's new (L1 / R1 scroll long notes), asks before installing, and leaves your games, saves, states, labels and settings alone. Updates are signed and checked before anything is replaced; if the new version doesn't start, the previous one is put back, and an update cut short by the Brick switching off is cleared away. Needs 20% battery or a charger.
• Also a little secret in the Update menu. Hint hint: If you input a well known video game code from the late 80's something happens
• HOME → System: LEDs, Date & Time and About are now under System, leaving the menu shorter.
• System → Auto Clock: with Wi-Fi on, the clock now sets itself from an internet time server, on connecting and every six hours. On by default; the time zone is still set under Date & Time.

v0.43

New since v0.42:

• Overlays for every system come with Slot: KrutzOtrem's Vanilla set for GB, GBC and GBA and CRT set for NES and SNES, made for the Brick. Thanks to @KrutzOtrem!
• Overlays with a grid or tint over the game (such as KrutzOtrem's LCD and DMG grids) now work: the game fills the part of the overlay that isn't fully opaque, at the size the overlay was drawn for.
• An overlay name too long for its row is shortened, and scrolls slowly while the row is selected.
• Gameplay → Auto Save: save the game every 1, 5 or 10 minutes, or never. It was every minute.
• Gameplay → Low Battery Shutdown: save and shut down at 3%, 5% or 10% battery, or never. It was 5%.

v0.42

New since v0.41:

• Screen settings are sorted by system: Game Boy / GBC, Game Boy Advance, NES and SNES each have their own page. NES and SNES shaders can now be set there too.
• Colour correction is set separately for the Game Boys and the GBA. A setting saved before keeps working for both.
• Overlays: put your own 1024×768 PNG overlays in Slot/Overlays/<system> and pick one on the system's Screen page. The game fits itself into the overlay's window. In game, HOME + L1 / R1 switches between them.

v0.41

New since v0.40:

• Choosing a label now ends with it peeling onto the cart like a sticker, on every cart. On GBA carts the front closes for it, then opens again.
  It is a bit rustic, so if you have proper experience with animations, feel free to modify it and open a pull request
• Low-battery warning on the F1/F2 lights: steady red at 15% or below, blinking at 10% or below, even with the lights turned off. Thanks to @wargenng!
• Fixed: the About screen showed the wrong version.

v0.40

New since v0.23:

• Wifi status icon on the shelf footer. Icons may change.
• Label Picker. Press Y when in the edit screen on a game cart. It has a label editor built in, so you can resize the label and make it fit the cart cutout
• Finally fixed Wi-Fi
• Customize cartridges: color, finish and shape for all shelves.
• Add SNES support: SNES and PAL cartridges
• Add NES support: NES and FAMICOM Cartridges
• Add RetroAchievements support, softcore only
• Automatic label fetcher in main menu, it fetches labels for all carts at once, but it is really barebones, so refer to the label picker for more control

FOR DEVELOPERS

• The Brick simulator - for testing in the browser before real hardware testing. Refer to the Development part of the Readme.
