DCDigital (formerly known as DCHDMI) is a modification kit originally created by Black-Dog Tech (v1) and now PixelFX (v2).
The modification adds native digital audio and video output (via HDMI port) to the Sega Dreamcast. The modification taps into digital video signals on the Dreamcast motherboard to generate pristine HDMI compliant video output. Installation requires advanced surface-mount soldering skills. The original version distributed by Black-Dog Tech is now discontinued, but both the hardware design and the firmware of the original version are open source, which has led to widespread availability through clone manufacturers. The second version developed by PixelFX expands the feature set and brings it in line with their PS1Digital and N64Digital products, but it is a proprietary product.
Black-Dog Tech version:
- Games that support the Dreamcast VGA video mode can output direct native 480p, line-doubled 960p, or 1080p created by placing a black border around line-doubled 960p.
- Games that do not support the Dreamcast VGA video mode can output direct native 240p/480i, deinterlaced 480i, line-doubled deinterlaced 960p, or 1080p created by placing a black border around line-doubled deinterlaced 960p. Only bob deinterlacing available.
- 960p is not a standard resolution and may not be compatible with all TVs or monitors.
- H2QX smoothing filter available, but relaxed non-HDMI compliant timings when turned on
PixelFX version:
- Custom zoom and aspect ratio
- Configurable horizontal and vertical interpolation
- 1440p (1920x1440) resolution video output
- Custom video modelines
- Slotmask/shadowmask filters
- Advanced scanline options
- Added weave and motion-adaptive interlacing
- XBR or H2QX smoothing
- CEC remote control
- pseudo-HDR
- Support for Naomi arcade systems
- Fully HDMI compliant
All current hardware modifications, such as overclocking, 32MB RAM expansion, BIOS modifications, optical drive replacements, 12V line removal, etc. are known to be compatible with DCDigital.
