--control=<P1[:P2[:P3[:P4]]]>

Set control scheme. The default is the Game Boy Player Start-up Disc's Controller setting (0 or 1).

0:	Type A (two-handed)
1:	Type B (one-handed)
2:	Type C (Super Mario World: Super Mario Advance 2)
3:	Type D (The Legend of Zelda: A Link to the Past)

Note: A Game Boy Advance used as a controller is a Nintendo GameCube Controller.

--delay-reset=<N>

Set reset delay (default: 0).

--delay-video=<N>

Set video buffering (default: 1).

--movie=<path>, --no-movie

Play input log (default: no).

--movie-record, --no-movie-record

Record input log (default: no).

--palette=<xxxx-xxxx-xxxx>, --no-palette

Apply Super Game Boy color palette (default: no).

Note: Press Left + B while the Game Boy logo is visible for proper application on original Game Boy Game Paks.

--lut3d=<path>, --no-lut3d

Load 32x32x32 lookup table in PNG file format (default: no).

Overrides --matrix, --input-gamma, --contrast and --brightness.

--lut3d-order=<rgb|gbr|bgr>

Specify lookup table order (default: rgb).

--matrix=<identity|gba|gbc|gbi|nds|palm|psp|vba>

Set color matrix (default: identity).

This translates the RGB color primaries to the video RGB color space.

identity:	Identity matrix
gba:	Game Boy Advance (by Pokefan531)
gbc:	Game Boy Color (by Pokefan531)
gbi:	Game Boy Interface
nds:	Nintendo DS (by Pokefan531)

--input-gamma=<red[:green[:blue]]>

Set gamma (default: 2.2).

--output-gamma=<value>

Specify screen gamma (default: 2.2).

--contrast=<red[:green[:blue]]>

Set gain (default: 1.0).

--brightness=<red[:green[:blue]]>

Set lift (default: 0.0).

--volume=<left[:right]>

Set audio gain (default: 0.75).

Note: GCVideo-DVI v2.4b and earlier reduces volume down to a quarter.

--sound=<[mono|stereo][,digital|analog]>

Set sound mode. The default is the Sound Mode system setting (mono or stereo).

digital

Use PWM decoder (default).

analog[=<a0:a1:a2:b1:b2>]

Use 2MHz biquad filter. Defaults to a second-order low-pass filter with a cut-off of 10kHz and a quality factor of √2 if not specified.

This is used to simulate the RLC circuit on the Game Boy Advance's Headphone Jack, providing a treble boost.

--colorspace=<ycc601|ycc709|ycc2020|rgb709|rgb2020>

Set video color space (default: ycc601).

This depend on a compatible video encoder or transmitter not mangling its input.

ycc601:	IEC 61966-2-4 xvYCC601
ycc709:	IEC 61966-2-4 xvYCC709
ycc2020:	ITU-R BT.2020 Y’C’BC’R
rgb709:	IEC 61966-2-1 sRGB
rgb2020:	ITU-R BT.2020 R’G’B’

Note: GCVideo-Lite or GCVideo-DVI v2.4d-2 and earlier will interpolate red and blue samples.

--chroma-location=<left|center|right>

Specify chroma sample location (default: center).

If non-center, this will interpolate luma samples.

--format=<[ntsc|pal|pal-m|ntsc-50|pal-60|custom|custom-m|hd60|hd50|hd48|hdcustom][,offset=<x:y>][,scaled-size=<w:h>]>

Set video format (default: custom).

Note: GCVideo-DVI is only designed to support NTSC, PAL and PAL-60.

--scan-mode=<[interlace|quasi-interlace|non-interlace|non-progressive|progressive][,clock2x|no-clock2x][,size2x|no-size2x]>

Set scan mode. The default is the Progressive Scan Mode system setting (non-interlace or progressive).

interlace:	15 or 18-22kHz interlaced
quasi-interlace:	15 or 18-22kHz segmented frame
non-interlace:	15 or 18-22kHz progressive
non-progressive:	31 or 27-33kHz interlaced
progressive:	31 or 27-33kHz progressive

clock2x, no-clock2x

Enable 27MHz pixel clock (default: auto). Enabling doubles the refresh rate for interlace scan modes. Disabling halves the refresh rate for progressive scan modes.

This depend on a compatible video encoder or transmitter not mangling its input.

size2x, no-size2x

Enable pixel doubling (default: auto). Enabling halves the refresh rate.

This depend on a compatible video encoder or transmitter not mangling its input.

--usb, --no-usb

Note: Remove any accessory from the External Extension Connector, or the Rumble Feature will not work.

Note: 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. Hold Start + Select while the Game Boy logo is visible.

Any file path can be relative or absolute. If relative, it is relative to /GBI. They can also explicitly specify the SD card to read from by prefixing an absolute path with carda: or cardb:

Comparisons

Video quality (480i/p)

These results will differ from the standard edition and speedrunning edition.
These results are not applicable to Nintendo GameCube software.

Using DSSIM 2.9.7 and FFmpeg 4.2 for RGB SSIM & PSNR, with this reference image.

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

Blackmagic Intensity Shuttle

Using ADV7180 and ADV7604.

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

FAQs

Progressive scan (720x480p)

Blanking regeneration (1440x480i)
Red + Green: Regenerated blanking interval
Green + Blue: Actual blanking interval

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 holding a direction 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.

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 or off-center?

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.

As a last resort, you can disable pixel doubling (--scan-mode=no-clock2x,no-size2x). This will degrade video quality and disable aspect correction for 4:3 displays.

How do I calibrate for this?

Damian Yerrick has ported Artemio Urbina's 240p Test Suite to the Game Boy Color and Game Boy Advance.

The Game Boy Advance port can be multi-booted by Game Boy Interface, skipping the need for a flash cart.
