what is dreamster fr?

DreamSTer combines two existing projects, polly2-rtl and minicast, together with a Python text based launcher, to bring Dreamcast game emulation to the MiSTer FPGA hardware platform. The README is upfront that this is an experimental setup and does not follow MiSTer's usual conventions, meaning it is not built as a standard MiSTer core the way most MiSTer add-ons are. Instead, the README describes its approach as intentionally rough around the edges: when launched, DreamSTer stops the currently running MiSTer process, takes control of the FPGA hardware directly, starts minicast to run the Dreamcast emulation, and then reloads the standard MiSTer menu and restarts MiSTer once the session ends. Setting it up means downloading the latest release, extracting it to the root of the MiSTer's SD card, and placing the required Dreamcast BIOS and flash files in a specific games folder on that card. Game disc files in formats like .cue.gdi, or .cdi can either sit on the SD card itself or on an external USB or NVMe drive, and DreamSTer can be configured with one or more explicit paths to scan, or left to automatically detect an external drive with a short grace period at boot to let USB storage finish mounting. The project is still gathering compatibility data and asks users to report which Dreamcast games work or don't through GitHub issues, pointing to a linked Discord server for further discussion and support.
