Comparisons

Video quality (480i/p)

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 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.

  1. 1.0 1.1 Generic S-Video Cable exhibits a checkerboard pattern when audio isn't connected.
  2. GCVideo-DVI v2.4a and earlier has CB shifted left in the Green channel of RGB outputs.

FAQs

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.

Why is my picture cut or off-center?

This is GCVideo-DVI's blanking regeneration misbehaving with unsupported video modes.

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.

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.
