# Supermodel: initial Real3D Pro-1000 image-generator emulation > Adds emulation of Real3D’s Pro-1000, the SCSI-attached image generator from which Sega’s Model 3 graphics hardware derives, to the Supermodel arcade emulator. It boots user-supplied Pro-1000 firmware from the SDK disc, emulates the board’s interrupt, JTAG and UART hardware, and exposes the firmware’s built-in monitor on the console. Nothing renders yet, and SCSI host communication is unimplemented. - Type: Case study - Targets: Firmware - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-18 - Added to the catalog: 2026-10-19 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/supermodel-real3d-pro1000-emulation-case/index.md) ## Requirements & limits - **Prerequisites:** Supply the Pro-1000 firmware images p1_p4.bin and p2.bin from the SDK disc; Config/Games.xml lists their CRC32 values, and the repository does not include them. The PR says the default scene and model data sat in a SCSI ROM that the SDK lacks and would have to come from original hardware that likely no longer exists; a synthetic SCSI ROM only gets past renderer initialization. - **Prerequisites:** Supermodel documents builds with GCC and Make on Windows (MSYS2, with SDL2 and SDL2_net), Linux and macOS, and a Visual Studio project; the PR adds its sources to the shared Makefile rules and that project. No Pro-1000 test or rendering comparison accompanies the change. - **Scope:** Reviewed at merge commit 4f5d686 of pull request #343, merged 2026-10-14, which adds a CPro1000 emulator class beside the Model 3 one. The PR boots the firmware to its UART monitor and accepts console commands such as help; it states that nothing is drawn, not even the start-up logo, and that SCSI communication is the next step. - **Limits:** Source comments describe the hardware findings as reverse-engineered working hypotheses drawn from firmware disassembly, logs of unmapped accesses and UART output, embedded SCCS module strings, address cross-references, part datasheets and the SDK manuals. Some registers and the JTAG scan chain remain unknown. - **License:** Supermodel’s source headers declare GPL-3.0-or-later; the firmware, SDK material and demo databases keep their own rights. The author’s X post credits Claude with doing the reverse engineering and writing the emulation, and credits co-author Ian Curtis with the earlier SCSI-interception demos. ## Primary sources 1. 2. 3. 4. 5. 6. 7. 8. 9. ## More in Firmware and hardware - [OpenDMCUFirm: a reimplemented Wii U DMCU display firmware](https://awesomerea.org/resources/opendmcufirm-wii-u-dmcu-firmware-case/index.md) · Case study - [reflecticon-224: running Lexicon 224 reverb firmware on emulated hardware](https://awesomerea.org/resources/reflecticon-224-lexicon-emulation-case/index.md) · Case study - [TeddyCloud: a self-hosted replacement for the Toniebox cloud](https://awesomerea.org/resources/teddycloud-toniebox-server-case/index.md) · Case study - [Valetudo: local replacement for robot-vacuum vendor clouds](https://awesomerea.org/resources/valetudo-robot-cloud-replacement-case/index.md) · Case study - [EchoMuse: replacement software that turns the Echo Dot 2nd gen into a Home Assistant voice satellite](https://awesomerea.org/resources/echomuse-echo-dot-voice-satellite-case/index.md) · Case study - [OSIRIS: replacing Onkyo receiver firmware through MCU protocol research](https://awesomerea.org/resources/osiris-onkyo-receiver-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
