Emulation Names - Part 5

David Haywood

David Haywood, known as Haze, was born in 1981 and lives in Derby, United Kingdom. He became famous around August 1999, when he was responsible for the MAME port, NeoMAME, specializing in the SNK Neo Geo MVS board. The following year, he began working on the Sega System C-2 emulation project, which ended up being continued by Charles MacDonald, who released the emulator that same year. 

NeoMAME

Raine

In July 2000, he joined the Raine arcade emulator team, remaining with the team until February 2001. He also contributed to the Sega Model 1 emulator Modeler in 2001 and the Sega Saturn SSE in 2002. David is also known as one of the major contributors to the MAME project. He joined the project in September 2000, and his contributions include improvements to Sega's Megatech, MegaPlay and ST-V boards in 2003. Improvements to the Konami GX, PGM, Hyper Neo Geo 64 (successor to the Neo Geo MVS) and Sega System 16 boards in 2004. Additions to the System 16A and B boards, changes to the Sega System C-2 board and fixes to the Sega System 32 board in 2005. In 2005 and 2006, he fixed the Neo Geo code. In 2006, he made adjustments to the 1st generation Psikyo board.

Websites Sega System C2 MAME Driver, Haze's MAME Page, David Haywood's Homepage and GitHub

He created the Sega System E driver, based on his HazeMD, in 2007, and added it in place of the old core. In addition, he added other arcade games to the project, such as Psikyo SH2, Taito JC System Type-C, CPS3, UPL, Sega System C-2, NMK16 System, Sega ST-V and attempted reconstruction of the Super Kaneko Nova System drive. In terms of adding games to the project, he was responsible for Tetris (Sega System E), Bonanza Bros, Head On, Bubble Bobble, Puzz Loop 1 and 2, Daytona USA, Galaxian, Crush Roller, Pang, Alien Storm, Ghosts'n Goblins, Magical Drop, X-Men, Sonic the Hedgehog 2 (Megaplay), Tant-R, Puyo Puyo, Dragonball Z 2 Super Battle, Arabian Fight, Sonic 1, Alien 3, Golden Axe 2, Taisen Tokkae-Dama, Street Fighter 2, Baku Baku Animal, among others, all arcade versions, some clones/bootlegs or updated versions and in partnership with other contributors to the project.

HazeMD

Within the MAME project, he created the Haze Megadrive Emu, or simply HazeMD, as it became known. It was an emulator developed using the existing structures of the project. Its goal was to faithfully reproduce the entire library of the console with precision, including cartridges that did not work correctly in other emulators. The project began in 2006. It was released externally until 2009, when it merged completely into the MESS project, which David also worked on. The emulator outside of MAME and MESS had no interface, working via the command line. Because of this, some ports of it were released, such as HazeMD32 and Haze MD32FX, both for Windows and with an interface similar to that used in MAME, and SDL HazeMD for the MacOS system. There was also HazeMD Plus! made by the developers of MAME Plus!, a port of MAME. Because of HazeMD, David became known as Haze. From 2007 onwards, David also contributed to the MESS project. Among his contributions is the introduction of his HazeMD emulator, bringing better compatibility and accuracy to emulation. In 2011, improvements to the Atari Jaguars and Neo Geo drivers. And in 2012, modernization of the Mega Drive, 32X and Sega CD drivers. He was on the project until the end, in 2015. After its end and merger with the MAME project, he remained only on MAME, where he had been working since 2000. Until 2021, David was still contributing to MAME.

Richard Mitton

TNZS-EMU

Richard Mitton (Nodrog/Spindizzy/Kayamon) was born in England and has enjoyed creating software since he was young. He was first fascinated by the ZX Spectrum, which is where he began to learn about software coding. In the mid-1990s, he came into contact with Gerton Lunter's Z80 Spectrum emulator, which fascinated him with the world of emulation. Shortly after, he began to get involved in arcade and console emulation.

TNZS-EMU Website

In 1997, he began to create the TNZS-EMU emulator for Taito's arcade game The New Zealand Story, as he himself says, inspired by the arcade emulation project MAME. Around 1997/98, he released his emulator and soon after, in 1998, he began working on the MAME project. In MAME, he only contributed in 1998 with fixes for Taito's game The New Zealand Story, thanks to the advances with his emulator. Around 1998/99 it was known as Nodrog. In 1999, he began to develop his Z80 emulator, inspired by Gerton Lunter, releasing it that same year under the name Raze. Along with Marat Fayzullin, Marcel de Kogel and Neil Bradley, he became the great creator of a Z80 emulator, changing the history of video game emulation. His emulator was used in several projects. Among them SMS Plus, MGX, Calypso and Meka from SMS in 1999, its own emulator TNZS-EMU from 1999, Modeler from Sega Model 1, Gens (for a few months), DGen and Genital from Mega Drive, Koleko from ColecoVision, FreezeSMS from SMS, Impact from Arcade and Sega System 16 Emulator (not to be confused with Thierry Lescot's System 16 Emulator) both in 2000, Neo Geo CD Emulator, Xega from Mega Drive and WinKawaks from Arcade (only for Neo Geo games) in 2001, NeoPop from Neo Geo Pockett (only at the beginning of the year) and GNGeo from Neo Geo in 2002 and NeoRaine in 2007.

Websites Coders Notes and Richard Mitton

Mitton's Z80 core is very complete, with a rich feature set and good interpretation, but it is not as fast as its competitor Multi-Z80. Mitton had the help of many influencers to create his Raze Z80. Among them, Ishmair, for his Maze Z80 and Neil Bradley for his Multi-Z80, Sean Young for his Z80 documentation and Charles MacDonald for testing his Raze on his emulators. In addition to his Raze, he created another emulator, the SND Sound Chip Emulator, in 1999, a software that could emulate several chips at the same time, helping, among others, in multi-hardware projects. It supported some models such as the PSG, YM2149 (also known as AY-3-8910), from Capcom, Taito, Konami and Sega arcades, PCs, such as the NEC PC 8801, Amstrad CPC, Atari ST, MSX and ZX Spectrum and consoles such as the Intellivision and SN76489, used in 8 and 16-bit consoles from Sega, ColecoVision and Neo Geo Pocket and arcades from Konami, Sega and others. The OPN chips, YM2203, mainly used in Capcom arcades, YM2610, from Taito and SNK arcades, such as the Neo Geo MVS and YM2612 from Mega Drive and the Mega-Play and Sega System 32 arcades from Sega. The OPL chips, YM3526 and YM3812, used in Taito arcades and in the Commodore 64 and MSX PCs. And the emulator of the Generic 8-bit DAC, a digital to analog audio converter that can be used on many different hardware. His TNZS-EMU emulator used his SND Emulator.

Raine

In 1999, he became part of the Raine arcade emulator team, where, among other things, he integrated his TNZS-EMU emulator, helped with the sound and added his MC68705 static recompiler, also created in 1999 to the project. He was known in the project as Spindizzy. He stayed with the project until around 2000. In addition to his microprocessor and chip emulators, he also contributed support, advice, help and bug fixes to other projects, such as Meka, pre and post launch in 1998 and 1999, helped SNEeSe with speedup implementation in 1999, contributions to the Model 2 Emulator in 2003 and help with the Sega 8-bit and 16-bit multi-emulator Regen for Linux in 2007. Richard also had other projects, such as the Intel i960 chip in 1999, which he attempted to emulate to run Sega Model 2 games. The Intel i960 chip emulator was used in his own emulator in 2000 and in the Model 2 Emulator in 2003.

Virtua

And speaking of his emulator, in 2000, he developed the Virtua emulator for Sega Model 2, the first prototype of the arcade, but he never finished it, leaving it available to the community for a possible continuation. He ended up emulating 11 games, but up to a certain point. At that time, he was known as Kayamon, a nickname that he is known by to this day.

Technical Information/Documentation for the Amiga 500, ZX Spectrum and NEC V60

Docs SND Sound, Raze Z80, Intel i960 and Motorola M68705

Richard provided technical information and documentation about some systems, such as the ZX Spectrum, Amiga 500 and the NEC V60 microprocessor (used in Sega's System 32 and Model 1 arcades). Some of this information was about emulators created by him, such as the i960, M68705 and Z80. He had plans to bring documentation for several other systems, such as the Sega Model 1, 2 and 3, CPS-1, 2 and 3 and Sega System 16 and 18, several consoles from Sega, Nintendo, Sony and SNK and microprocessors from Motorola, but he never did.

ROM Hacking Programs

He also posted important tools for hacking ROMs, which helped to identify and fix problems in them. Some of them were created by Richard, such as Bswap and ILeave, around 2000/2001, important for modifications in 68000 games. One of his last updates on his website was in late 2001, when he created a patch for the PC game Silver by Infogrames to run on a GeForce card. In 2002, he created a new website, and there he put his main projects, such as Silver GeForce, Raze Z80, TNZS-EMU and Amiga 500. In 2003, he created the TNZS/GBA project, to convert the game The New Zealand Story to run on the GBA. The project was 95% complete, but was never released.

Very Sleepy

At that time, he left his hobbies aside to dedicate himself to creating games at Climax London, where he worked. While at Treyarch (another company where he worked in game creation), he returned to his hobbies and created a third website in 2007 dedicated to the creation of some software related to software programming, such as Very Sleepy (2007), a C/C++ CPU profiler for Windows systems, XJam (2008), a Jam compiler, a simple software creator, among others. Later, he turned his website into a kind of personal blog, which he has maintained to this day.

GitHub and ImGui

In 2014, he opened an account on GitHub and started posting his projects. Among them, we have AssimP in 2012 (made before GitHub), a library for importing and exporting 3D model formats for C and C++, in addition to the possibility of running in other languages, such as Java, Python, Delphi and D, STB in 2014, several single-file public domain libraries for C and C++, Forsyth in 2014, a program for optimizing a specific cache for optimizing 3D renderings, ported the FASTBuild program in 2015 for software development for Windows, Macintosh and Linux to an improved version, GoalDis in 2017, a disassembler of code and data from the PS2 game Jak and Daxter, RJM in 2017, several single-file libraries in C and C++, ImGui in 2019, a graphical interface library in C++, in addition to making available in 2019 a list of several single-file libraries made by third parties.

Speed ​​Kings (NGC), Call of Duty (Wii) and Transformers (Xbox 360)

In his personal life, he studied computer science at King's College London from 1998 to 2001, where he also graduated with a bachelor's degree in science. In 2001, he joined Climax London, a game development company. At the company, among others, he was behind the creation of the games Speed ​​Kings for GameCube in 2003, published by Acclaim Entertainment, and Delta Force: Black Hawk Down for Xbox in 2005, published by NovaLogic. He also created texture codes and other codes for the Xbox, in addition to developing AI. In 2005, he moved to the United States, where he lived in Santa Monica, Los Angeles, California. His intention was to expand his horizons and take great flights. That year, he began working for Treyarch, where he worked as a machine programmer, additional engineer, engineer and senior engineer. He was also a senior graphics engineer, helping to create tools and libraries (such as Calls of Duty BRO, 3, WAW, and BLOPSA), integrating Xbox libraries into games created for the console, and working with shading and lighting in games. The company created games for Activision. Richard was behind titles such as Call of Duty 2: Big Red One, 3, 4: Modern Warfare, World at War and Black Ops and Spider-Man 3, for systems such as GameCube, PS2, PS3, Xbox 360, Wii and Windows. In 2009, he had a brief stint at Luxoflux (where, by the way, several emulator creators passed through), working on the game Transformers: Revenge of The Fallen for Xbox 360 and Windows, also for Activision, returning that same year to Treyarch. In 2010, he left the company. In 2013, he was behind the creation of the game Sky: Children of the Light for iOS and Android, at thatgamecompany, also in Santa Monica, where he was hired as a senior engineer.

Climax London, Treyarch, Luxoflux, That Game Company, RAD Game Tools, Texture.com, Yacht Club Games and Activision Blizzard

In the game, he was responsible for rendering, performance and memory management, among other things. In the same year, he moved to Kirkland, Washington, where he joined RAD Game Tools as a software engineer, a company responsible for developing tools for creating games. There, he was responsible for implementing libraries in a debugger created by the company, called CPU RAD. His position was temporary, and he left the company in 2014. In 2015, he began working remotely as a freelancer for a Dutch company called Texture.com, which worked in the area of ​​image editing/effects. Richard developed tools for scanning 3D images, data flow processing and LED light control for image capture, and a GPU-accelerated graphics shading editor. He worked at the company as a software engineer, leaving in 2019. In the same year, the game Sky: Children of the Light for iPad was released, which he had helped develop in 2013. In 2020, he moved to Los Angeles, California, where he joined Yacht Club Games as a senior tools and engine programmer. He works mainly on the engine core, 3D editing and collision mechanics in games. Richard was behind the games Cyber ​​Shadow and Shovel Knight: Pocket Dungeon in 2021 and Shovel Knight: Dig in 2022, both for Windows. In 2022, he went to Activision Blizzard, also in Los Angeles, as an engineer who works on the core and the entire game process, from start to finish (the so-called pipeline). Richard was in charge of the games Call of Duty: MWII - Modern Warfare II in 2022, for Xbox Series and Windows and Call of Duty: Modern Warfare III in 2023, for PlayStation 4. Until the publication of this article, he was still working at Acitivion Blizzard.

Richter Belmont

Modeler (Windows)

Richter Belmont (Arbee, abbreviated as RB), or simply R. Belmont, as he is known, was born in 1974 in the USA and lives near the American east coast. Richter entered the world of emulation around 2001. Initially, he worked on the Emuhype project, a group of arcade developers from 3D and Sega. At the time, he was responsible for bringing the Modeler project for Sega Model 1 and Sega System 32, created in 2000, to the Emuhype team of which he was a member. From that moment on, he was responsible for the ports for Linux in the project. In the same year, he created the Konami GX Player sound emulator, known as GXP, which played music from nine games on the arcade board. Also in 2001, he created the M1, a sound player that played music from 1,918 games, from a total of 269 boards, recording them in .WAV format. He even ripped many of these songs and made them available for download on the website.

Modeler (Windows)

Modeler (Linux)

M1 lasted until 2007. In the project, he was also responsible for the ZiNc emulator for PSX-inspired arcades from late 2004, after Duddie left. He took care of it until its closure in early 2005. Linked to the ZiNc project, in 2006 he developed a sound player for the System 11 board, the System 11 Player . This player was used in the ZiNc front-end, the ZeNith, to reproduce the sounds of System 11 games. ZeNith allowed the customization of sound, video and control parameters, verification of the integrity of ROMs, execution of games and others. It came with support for the user interface in Russian, Traditional Chinese and English. ZeNith was developed by third parties. Outside of the project, in 2002, he indirectly helped with the emulation of the Sega Titan Video board in the Sega Saturn emulator, SSE. In 2007, he created the Linux port of the NES emulator, Nestopia, but without making a binary available. 

ZiNc

ZeNith (ZiNc Front-End)

He was a moderator of Richard Bannister's forum from 2007 to the present day. In 2011, he provided some assistance in the Supermodel project for the Sega Model 3 board, such as digital sound emulation in MPEG, among others, since he had worked on the emulation of the first board in the series in 2001 and helped port the second to the MAME project in 2004. In personal projects, in 2007 he developed the Audio Overload SDK, a player that played music in PSX, PS2, Sega Saturn, Dreamcast and QSound formats and in 2008 VIO2Play, a simple command line version of the VIO2SF plugin that plays music in the .2SF format (corresponding to Nintendo DS games) on the Linux system. It came ready to be integrated into other software in Windows and Linux versions. It was written alongside Richard Bannister and developed until 2009. He made some songs ripped from PS2 with this program available for download. At the same time that he joined Emuhype, he joined the MAME project. This occurred at the end of 2001.

Audio Overload

At the time, he began by adding the Sega Model 1 V60 CPU from the Modeler project alongside Farfetch'd. In 2002, he created the emulation of the YMF278B sound chip, the famous OPL4, alongside Oliver Galibert, used in the Psikyo SH2 board. This chip was later present in the OpenMSX (2003) and FBA (2005) emulators, as well as the VGMPlay (2011) player, which played music from various Yamaha chips and others. In 2006, he added MAME to SDL mode, to better port it to other systems. Richter added some arcades to the project, such as Namco System 22, Namco System 23, Konami GX, Konami Bemani Twinkle, Sony ZN-1 and 2, Sega Model 2 and 3, and alongside Samuele Zannoli, ElSemi, Angelo Salese and Olivier Galibert, helped add the Sega Naomi 1 and 2 and Atomiswave boards, among others.

GXP and M1

Despite these contributions, his greatest role in the project was adding corrections, updates and modifications to Konami boards, such as GX400 and PPC, Namco boards, such as System 23, 22, 12 and Super 22, Sega boards, such as Model 1, 2, 3 and ST-V, Capcom boards, such as CPS-3, Nintendo boards, such as Super System and Playchoice 10, among many others, as well as consoles such as Dreamcast, PS1, GBA portables and the Apple II PC, in addition to processors and chips that act directly on the aforementioned hardware. He was also responsible for adding games such as Alien 3, Golden Axe 2, Spiderman, Violent Storm, Taisen Puzzle-Dama, Outrunners, Taisen Tokkae-Dama, Tokimeki Memorial Taisen Puzzle-dama, Capcom Vs. SNK Millennium Fight 2000 Pro (alongside ElSemi, David Haywood and others), Dragon Ball Z, Dragon Ball Z 2 – Super Battle (alongside David Haywood and Pierpaolo Prazzoli), among others. 

Docs: ZiNc, M1, NEC V60/V70, YMF278B, Overload and SDL MAME 

He began contributing to the MESS project in 2005, where he was responsible for several improvements in support for CD-ROM, keyboard, mouse and others, and corrections to drivers for systems such as the TRS-80. In 2006, he added the SDL mode to MESS, to better port it to other systems. In 2007, he added systems such as the Sega Saturn, Apple II, Mac 128k, Sega Dreamcast, corrections to the Famicom, preliminary CD-ROM support, input support and fixed sound for Sega Saturn games, as well as adding David Haywood's MD emulator, HazeMD, having been working on adding it since 2006. In 2008, he added support for the Sega Saturn ROM cartridge and the American Mega Drive.

Websites Richter Belmont, Richard Bannister (Forum) and EmuHype

In 2009, he added the Neo Geo AES, GBA, Gamepark 32, GP2X and Macintosh II to the project, as well as initial support for controllers and a GD-ROM drive for the Dreamcast. In 2011, he began to be responsible for the MESS ports in SDL language. Also in 2011, he added emulation instead of simulation of the SNES ST-010 chip and support for CD-ROM and Memory Card to the PSX. During all this time, his greatest work on MESS was undoubtedly on the Apple II computer and Macintosh computers. He worked on MESS until its end in 2015. After the end of the project, he remained only on MAME, and has been with the project to this day. He is considered one of the most active contributors in the entire history of MAME.

GitHub and MAME SDL

In 2014, he joined GitHub, where he made some of his projects available. Among them, we have MAME SDL in 2016, a project that began in 2006, transforming MAME into an emulator convertible to other platforms, posting on GitHub all MAME SDL versions from December 2007 onwards, KEGS-Universal in 2018, a project so that the KEGS Apple IIgs emulator can also run ROMs from the Apple II, II+, IIe, IIc and IIc+ models, A2 Softlist Support in 2019, a set of scripts and hacks that act on the Internet Archive digital library (archive.org) in order to obtain information from old ROMs to enhance MAME, mainly Apple II ROMs, RasterOps in 2023, sharing the original source code of declaration ROMs (a firmware embedded in video cards, informing the main system when there are new cards connected to the video bus, in addition to providing information about them), mainly from NuBus and Unirom video cards in 2020, a project that allows the KEGS Apple IIgs emulator to run ROMs from the Apple II, II+, IIe, IIc and IIc+ models, and a new version of the KEGS Apple IIgs emulator. 2023, to extract information from ROMs for Macintosh computers created before the creation of the 1998 iMac, being extractable from both the MacOS system and the Linux system.
