About DreamPotato

A Dreamcast VMU emulator currently in beta.

What's new in 1.0.0

DreamPotato has reached 1.0 (stable)! Thank you for all your support and encouragement as I have worked continually through this project.

Hollycast Integrated Mode

See demo video:https://www.youtube.com/watch?v=HkwDi5smav4

DreamPotato now integrates with Hollycast, a new fork of Flycast. This represents a big improvement to ease of use!

> [!TIP]
> Consider downloading from the Hollycast release page instead. This will get you both Hollycast and DreamPotato at the same time, and with versions that are known to work with each other.

The new integration allows:

  • Automatically launching DreamPotato and connecting back to Hollycast, for any number of Dreamcast ports. All you have to do is pick DreamPotato as the expansion device type in Hollycast.
  • Automatically using the VMU file from Hollycast. Even per-game VMU A1's "just work" in DreamPotato now. (fixes #12.)

VMS Folder

41 added "Open Folder" and "Save as Folder" commands. This exposes the individual game saves in a folder on your hard drive, similar to Dolphin's "GCI Folder" support.

This improves the experience of importing/exporting individual game saves on your VMUs. See https://github.com/RikkiGibson/DreamPotato#open-folder for details.

Audio Improvements

46 improved audio accuracy, especially in Soul Calibur 3-in-1. You should notice a general improvement in clarity of the beeps and boops made by the emulated buzzer.

App Icon

We have a new app icon drawn by @ruva! The blocky programmer art we had before is no more.
