God I love the Dreamcast. What an amazing failed console. It was ahead of it's time. It was a console we didn't deserve it, but the console we needed. So many great arcade games that were direct conversions *not ports*, since the the DC is built under the same hardware as the Sega Naomi.
I own a Sports Edition, the cool black console, but I wanted to upgrade it for modern gaming. Enter the DC Digital. Amazing device that adds HDMI output to your DC!
I already had an ODE (optical drive emulator) called the USB-GDROM, that removes the original drive and you're able to run your game images off a USB device like a HDD or Flash drive. This ODE has served me really well for a while!
But it requires you to disable the 12v rail (since that's used for the optical drive) to reduce system overheating from the PSU. Then, a good measure is to add a new Noctua silent fan. He's the fan installed with a custom 3D printed mount:
I opted for a high capacity Flash Drive connected to the back of the system. I'm running a 215gb Samsung Fit Plus drive, which is more than enough space for all the good games on the system. Attaches to the back:
The DC Digital is a small board that mounts above the metal shield, and taps the digital video signals straight from the motherboard. Ribbon cables are soldered various points and SMD chips and fed to the DC Digital board.
The HDMI-mini port is cut out in the back of the console right under the venting holes. This was a clean install!
The results? Clean crisp high resolution HDMI video! Every Dreamcast game looks amazing!
