DreamPotato v0.3.0 is released. DreamPotato is a Dreamcast VMU emulator in currently in alpha. For the moment only Windows builds are available. DreamPotato can connect to Flycast to support an experience similar to using a real Dreamcast and VMU together. Currently, trying this out requires building the Flycast vmuconn branch from source.

DreamPotato Changelog:: Cross-platform improvements
Mac release is now available for download! It is code signed and notarized, so should be easy to get it running. (#40)
Linux release is now an AppImage. (#39)
Both Mac and Linux now write user data (config, savestates, etc.) to conventional folders, instead of inline with the executable. You can still easily access the folder using Settings->Open Data Folder.
Debugger
DreamPotato now has a built-in debugger under Emulation->Open Debugger. It is not feature complete and may crash if the window size is too small. But it has been very useful so far for investigating accuracy issues, debugging homebrew VMU programs, etc. (#33)
Further, the VMU assembler waterbear can now output debug info, which will be automatically found and used by the debugger. This means the label names, variable names, etc. used in the original assembly code, will appear in the debugger. Thanks @wtetzner! (#36)
Other Improvements
Accuracy improvements for Pacman and Power Stone Mini (#26, #31)
Flycast quality of life improvements (#23, #21)
Startup perf improvements (#25)
AutoInitializeDate now respected at startup (#27)
