Naomi emulator roms driver#
NAOMI & Hikaru driver emulation was still being worked on since then up to 0.201 (Aug 2018).ĭo not add any emulator columns that are not worth adding. v0.191 (Oct 2017) supports SuperH CPU cores and has a preliminary SH3/SH4 recompiler for CV-1000 only. It is shown to have adequate support of the NAOMI (Most games could show graphics & some are playable), and preliminary support for Atomiswave and Hikaru boards and at least BIOS support for NAOMI 2. MAME is a long way behind DEmul in terms of compatibility but is being actively developed.However, its libretro arm now supports partial emulation of NAOMI and Atomiswave boards. The emulator has since been superseded by its follow-up spin-off, 'reicast', although that one doesn't yet have any arcade board support. Its compatibility is unknown, so is not included in the NAOMI compatibility chart below. nullDC was the first independent, open-source Sega Dreamcast emulator to attempt emulation of the NAOMI arcade board.Atomiswave support was initiated around November 2018. It is possible that some optional hacks are used to achieve correct graphics on some compatible arcade games. Flycast is a fork from the independent reicast emulator avaliable as a standalone emulator and as a libretro core and seems to be more advanced in overall compatibility and feature levels of Dreamcast and several arcade boards emulation.DEmul is a closed-source emulator for Sega Dreamcast and arcade boards of Sega NAOMI and follow-up variants, including the NAOMI, Atomiswave, Hikaru, Gaelco, NAOMI 2, System SP (Aurora) and couple Cave CV1000 systems.The Cave CV1000D had a new CPU which was an ISSI IS42S32400D at 166 MHz with 128MB of RAM. Note, the 'arcade_compat.txt' file inside DEmul's release archives do not have any Cave CV1000 emulation compat list, so its games' status is unknown. The Cave CV1000B had a Hitachi SH-3 at 133 MHz. Not really the same as SI Electronics' "Aurora", commonly mislabelled as "Sega Aurora". The Sega Sammy Atomiswave, more commonly referred to as the Atomiswave, has a Hitachi SH-4 CPU at 200 MHz with it's GPU being a PowerVR 2. A prototype version of an unreleased game called Jet Squadron was made on the NAOMI 2 board in 2000 but the first officially released games started in 2001. The Sega NAOMI 2 had 2 PowerVR CLX2 GPUs, a PowerVR Elan chip, and 2X the graphics memory. There is also an inactive emulator for the unrelated earlier Gaelco 3D system, and MAME supports that one. Not their early 'Gaelco 3D' board from 1996-1998. PowerVR 2-based board from Spanish company. The CPU was a 2× Hitachi SH-4 CPU at 200 MHz and the GPU was a 2× NEC-VideoLogic PowerVR 2 (PVR2DC/CLX2). The Sega Hikaru had a specific Motorola 68000 CPU just for networking. The CPU was 2× to 16× Hitachi SH-4 CPU at 200 MHz with the GPU being either 2× to 16× NEC-VideoLogic PowerVR 2 (PVR2DC/CLX2). The Sega NAOMI Multiboard had 112 to 869MB of RAM. The Sega NAOMI had a Hitachi SH-4 CPU at 200 MHz with 56MB of RAM (568MB of RAM with GD-ROM) and a NEC-VideoLogic PowerVR2 (PVR2DC/CLX2). Sega Hikaru had its own Sega Custom 3D GPU composed of dual PowerVR 2 GPU chips. Many of them also utilized their own Yamaha audio chipset. The exception was the Cave CV1000 which ran on a Hitachi SH-3 CPU and its GPU was the Altera Cyclone EP1C12 FPGA. Next, all but two of these various boards shared their own form of the PowerVR 2 graphics processor with some differences in specifications (eg. The NAOMI board and almost all of its variants were united in common by running on mostly the SH-4 32-bit RISC CPU.
The Sega Chihiro, or possibly even the Sega Lindbergh, could also be seen as successors. The NAOMI was succeeded by the Sega Hikaru and Sega NAOMI 2 boards, though having out-lasted the NAOMI 2, Hikaru and Sega System SP. It was designed as a successor to Sega Model 3 hardware, using a similar architecture to the Sega Dreamcast.
The NAOMI ( New Arcade Operation Machine Idea) is an arcade system released by Sega in 1998.
