Supermodel - RetroBIOS¶
Technical notes
Open-source Sega Model 3 arcade emulator by Bart Trzynadlowski (trzy) and contributors, under GPL-3.0. Emulates all three Model 3 steppings (1.0, 1.5, 2.0/2.1) including Real3D graphics, SCSP sound, DSB1/DSB2 MPEG music boards, drive boards, and net board. Cross-platform (Windows, Linux, macOS).
Uses MAME-compatible ROM sets loaded from ZIP archives. GameLoader identifies games by CRC32 checksums defined in Config/Games.xml. Parent/child ROM set relationships exist between regional variants of the same game, not as shared BIOS sets. No standalone BIOS or firmware files are loaded outside of game ZIPs.
EmuDeck installs the Flatpak package (com.supermodel3.Supermodel). Config stored in ~/.supermodel/Config/. No checkBIOS entry in EmuDeck.
No BIOS or firmware files required.
Why no files
The Sega Model 3 arcade hardware has no shared system BIOS. Each game board contains its own program ROMs (CROM), video ROMs (VROM), sound program, sound samples, and optional DSB/drive board ROMs, all contained within per-game MAME-format ZIP archives. Supermodel loads all required data from these game ZIPs via CRC32-based identification defined in Games.xml. No standalone BIOS or firmware files are referenced by the emulator source code.
