notes: |
|
|
Closed-source Windows emulator for Sega Dreamcast and related arcade hardware.
|
|
Run via Wine (32-bit, win32 prefix) on Linux platforms (Batocera, RetroBat).
|
|
Uses MAME ROM naming conventions for arcade BIOS archives.
|
|
|
|
Batocera configgen (demulGenerator.py) maps roms0 to the BIOS directory.
|
|
All BIOS ZIPs are placed directly in bios/ (no subdirectory prefix).
|
|
Demul searches configured ROM paths for both game ROMs and BIOS archives.
|
|
|
|
Gaelco PowerVR and Cave CV1000 (3rd gen) games are self-contained ROM sets
|
|
and do not require separate BIOS archives.
|
|
|
|
HLE MIE emulation available (changelog: "full HLE MIE" mode). LLE mode
|
|
requires mie.zip with the 315-6146 MCU firmware.
|
|
|
|
Supported launch modes via -run= parameter:
|
|
dc, naomi, naomi2, hikaru, atomiswave, gaelco, cave3rd, segasp.
|
|
|
|
BIOS requirements verified against Batocera configgen, batocera-systems
|
|
declarations, MAME ROM set conventions, and community documentation.
|
|
No source code available for direct verification.
