If you're using an EverDrive-GBA, make sure to turn off Quick Boot in the options, or the enhancements may not work.
<path>
Load Game Boy Advance multi-bootable ROM.
Note: Remove any accessory from the External Extension Connector, or the program will not load.
The e-Reader need to be pulled out slightly from the Game Pak Slot for a program to be loaded and interact with the e-Reader.

Any file path can be relative or absolute. The working directory is the first, non-empty GBI/ directory found in Memory Card Slot A, Memory Card Slot B, Serial Port 2, or GC Loader. The device can be specified with the prefix carda:, cardb:, sd:, or dvd:.

These results will differ from the speedrunning edition and high-fidelity edition.
These results are applicable to Nintendo GameCube software.

The analog-to-digital conversion parameters were calibrated for each source and device pair when possible.
This isn't representative of relative signal strength. Sorting by SSIMULACRA provide a fairly accurate ranking.

This 10-bit YCBCR 4:2:2 capture device is most representative of what you might see on a digital television.
As chroma is shifted right on YPBPR in/out, this was corrected in post-processing. Video and S-Video in/out suffer from internal interference.

This 10-bit YCBCR 4:2:2 capture device is most representative of what you might see on a digital television.
As chroma is shifted right on YPBPR in/out, this was corrected in post-processing.

Important: Misuse will result in the wrong aspect ratio. These settings are mutually exclusive with a secondary display.

Video capture devices (Game Boy Color)

These settings provide a 4× scaled image in a 5:4 576i50 (13.5MHz÷864÷625) or 576p50 (27MHz÷864÷625) video output.

If you're using GCVideo-DVI, under "Advanced settings", set "Digital color format" to YC422.

How do I change Game Paks?

  1. Hold the Reset Button.
  2. Slide the Game Pak Ejector.
  3. Insert a Game Pak into the Game Pak Slot.
  4. Release the Reset Button.

Can I play Game Boy Advance Video?

Yes. You can do so by disabling Game Boy Player enhancements (--no-enhance, or "Rumble: No" in Swiss), or holding a direction in the Game Boy Player while the Game Boy Player logo is visible.

Is this an emulator? Can I play ROMs?

No, but there's Enhanced mGBA if you're looking for one.

Is it possible to dump Game Boy Game Paks?

No, the pin assignment for the ARM7 CPU is different and prevents any such possibility. Using the SM83 CPU is impractical.

If you're interested in backing up Game Boy Camera photos, you can do so by taking a screenshot.

Why am I seeing a double split image?

Either progressive scan mode is enabled or, if using GCVideo-DVI, line doubling is by default.

If line doubling is at fault, the picture may also be scrolling with a slant.

Why is my picture cut-off or cut-through?

This is GCVideo-DVI's blanking regeneration misbehaving with unsupported video modes. In most cases, no user action is necessary with GCVideo-DVI v3.0 and later.

If you have a GCDual or EON GCHD Mk-II, under "Other settings", set "Analog output" (Wii RGB Cable) or "Mode Select" (Wii Component Cable) to dYUV.

For standard video modes, you can disable video oversampling (--scan-mode=no-clock2x,no-size2x, or "Video Oversampling: No" in Swiss).

Why is my picture square or narrow?

By default, Game Boy Interface assume a widescreen aspect ratio when using progressive scan.

Ensure that the television's settings match the assumed aspect ratio written in the top right corner of the on-screen display.

Why is there motion blur? Can I turn it off?

It removes stuttering caused by mismatches between the Game Boy Advance and the display refresh rate. It cannot be turned off.

It can be reduced by using a 120Hz video mode, but it's most effective on a sample-and-hold display.

This can possibly be confused with the deflickering filters. These can be disabled (--filter=none, or "Filter: Sharp" in Swiss).

Why are the colors washed out?

The screens used in the Game Boy family produced a smaller gamut of colors than found in the standard RGB color space on contemporary monitors.

Developers compensated for this to varying degree, resulting in odd-looking oversaturated colors when shown as-is.

By default, Game Boy Interface adapt these colors for the standard RGB color space, but only halfway as a compromise.

A low quality conversion from analog video can also cause washed out colors, as can color range mismatches in digital video.

What happens when I exit Game Boy Interface?

The Game Boy Player keeps running and you're returned to autoexec.dol, or the Nintendo GameCube Main Menu.

If using Swiss v0.5r979 or later, its reload stub is called.

Should I force 240p?

Generally speaking, no.

If you're using GCVideo-DVI, the results between 480p and line-doubled 240p are identical at 2× zoom. At greater zoom, 240p is just plain worse.

If you have a specific need for 240p, you're likely better served by the speedrunning edition or high-fidelity edition.
