Dreamcast GD-ROM replacement. WIP! Untested and not in production state!!!

Will use RP2040s and SD Card to emulate the gdrom drive.

Dreamdrivecast v1a: common questions

What microcontroller does the Dreamdrivecast v1a use?

The Dreamdrivecast v1a is built around the MCU1_BOOT, from the RP2040/RP2350 family.

How big is the Dreamdrivecast v1a PCB?

The Dreamdrivecast v1a measures 96 × 82 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Dreamdrivecast v1a?

66 components, from 35 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Dreamdrivecast v1a design files?

From the khill25/Dreamdrive repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Dreamdrivecast v1a design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Dreamdrivecast v1a without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
