Add pictures to your library?

dingbat can open each game, pick up where you left off, take a picture of the screen for its library card, and close it again. It takes a few seconds a game. Your games and saves are not changed.

You can do this later from Add pictures, above your library.

Opening a game from the library

Resume goes back to the moment you left. From save starts from the game’s own save, and offers the moment after.

Rewind Hold the rewind button to jump back, or double-tap it for a timeline you can scrub. Costs a few percent of speed; turning it off hides the rewind button.

Response and feedback

Run-ahead

Cuts the delay between pressing a button and seeing it happen, by guessing that many frames ahead. Costs extra CPU; ignored at 2× speed and in multiplayer

Rumble Buzz and shake when a game uses its rumble motor

Show inputs on screen Light up a small controller over the game as you press buttons — for streams, or for watching your own inputs. Recorded clips never include it.

Game Boy screen

Palette

The four colors black-and-white games are drawn in. Color games are never affected.

Super Game Boy games bring their own colors, so there are no shades to replace. Turn it off below to use a palette.

In use

Pick

Super Game Boy

Super Game Boy mode Adds color, and a border, to black-and-white games that were made for the Super Game Boy adapter. Other games are unaffected.

Show border A border makes the picture wider, so the screen changes shape when one appears.

Boot ROM

GBC boot ROM Not set

With a boot ROM set, Game Boy games play the startup animation first.

BIOS

GBA BIOS Not set

Play BIOS intro Play the GBA startup animation first. Needs a BIOS file

BIOS calls (SWI)

HLENo BIOS file needed Real BIOSThe most faithful. Needs a BIOS file Real BIOS boot, HLE callsReal startup, software after that

Changes apply the next time a game is loaded.

Screens Automatic shows both screens whichever way they come out bigger. Focus shows one large and the other small; tap the top screen to swap them. The screens button in the top bar has these too (V on a keyboard)

Gap

How far apart two screens shown together sit. Like the console is about the real distance, in pixels

Turn

For games played with the console held sideways like a book. Book, left puts the touch screen on the right (O on a keyboard)

3D resolution

Draws the 3D scenes at a higher resolution: sharper edges and models, the same textures. 2D stays as it is. Each step costs a lot more work a frame, so a slower device may not keep full speed

Bottom screen first Swap the screens: the touch screen on top, or the large one in Focus (B on a keyboard)

Hide the top bar while playing On a phone held upright, the screens take the bar's room. The handle at the top brings the bar back

BIOS and firmware

ARM9 BIOS HLE

ARM7 BIOS HLE

Firmware Built-in

None of these are needed: without them DS games run on dingbat's own BIOS and a built-in firmware. Dumps from your console (bios9.bin, bios7.bin, firmware.bin) apply the next time a DS game starts.

Built-in firmware

The console's own settings, which games read for your name, birthday and language. A game (or the DS menu) that changes them keeps the change, on this device only; your firmware.bin stays as it is, and Reset goes back to its settings. Changes apply the next time a DS game starts.

DS games stay on this device: Google Drive sync skips them, and save states, rewind, the link cable and cheats are not available for them yet.

Color correction Match the colors the original screen produced

Filter Smooth the pixel art, or draw the screen's own grid and subpixel structure

Integer scaling Keep every pixel exactly the same size

LCD response Colors settle slowly, the way the real screen did, so flickering sprites look see-through instead of blinking

Ambient glow Fill the background with a soft glow of the screen's colors

Audio interpolation Smooths GBA music between hardware samples for cleaner treble. Turn off for the exact sound of a real GBA's headphone jack, grit included.

Enhanced music synthesis Experimental. Re-creates supported games' music engines at higher quality than the hardware could mix. Changes the sound's character; engages itself only where it works.

Pitch-correct fast-forward Keep the pitch normal at 2× speed instead of everything sounding like chipmunks. Uses a little extra CPU, only while fast-forwarding.

Analog filter Soften the treble the way the GBA's own output filter and speaker did. Pair with interpolation off for the closest real-hardware sound. GBA games only.

Play in Silent Mode Pauses audio from other apps while a game is playing.

Mute parts of the sound to hear the rest on its own. Stays until you turn it back on or reload the app.

Tone channels The square, wave and noise voices every Game Boy and GBA game uses (PSG)

Sample channels Recorded sound and most music in GBA games (Direct Sound); Game Boy games have none

App theme

Google Drive

Force update Re-download the app and reload. Only needed if an update seems stuck.

Diagnostic log The app's log and build details, ready to paste into a bug report.

Save webhook Every time a game writes its save, also send the save file to this address as an HTTP POST (form field “save”). Leave empty to turn off. Synced to your other devices when signed in.

DS Beta Lets Nintendo DS games load. An early, incomplete DS core: some games won't run. Turned off, DS games leave the library until it is on again; their saves are kept.

Reset all settings Put every setting back to its default. Your games and saves are kept.
