Thierry Lescot (ShinobiZ)

Thierry Lescot, known as ShinobiZ, started the System 16 Emulator because the Sega arcade boards he cared about had no convincing home-computer substitute. The project reached DOS users in 1997 and helped show that 16-bit arcade hardware could be a focused emulation target.

A Sega fan chooses a hard target

The name ShinobiZ gives away part of Lescot’s enthusiasm. Sega’s arcade games had a distinctive look: large characters, layered scenes, music that could fill a room, and visual tricks that made a cabinet feel more powerful than the home console nearby. Lescot began exploring System 16 hardware in 1996 after looking for an emulator that could handle it. When the existing scene offered no ready answer, he began one himself. That origin is common in emulator history. A programmer’s first motivation is often not a grand preservation plan but a particular game they miss.

System 16 was not a trivial variation on an NES. Sega’s boards combined processors, sound hardware, graphics systems, and game-specific details. A screen could look close while motion or scaling was wrong. A game could draw its title and fail when the first interactive scene began. Lescot’s work had to move through those layers. The first DOS release in February 1997 made his project visible to other programmers and players, and each new result gave the community another reason to inspect the hardware closely.

The project’s title can make it sound more comprehensive at first release than it was. Emulation projects often begin with a narrow set of working games, then widen unevenly. Lescot did not have an official map of every Sega board behavior. He had experiments, observations, code, and help from a growing scene. A preserved screenshot of a later interface cannot tell us precisely what a February user saw. The official project page and contemporary directories do establish the author’s name and the scope of the effort.

Li Jih Hwa joins the work

An important turning point came when Li Jih Hwa, known as Nao, worked on the project. Retrospective accounts describe a patch that improved zoom behavior in Altered Beast and helped Golden Axe become playable. Lescot recognized the value of that contribution and invited Nao to collaborate. The partnership was not ceremonial. As other commitments limited Lescot’s time, Nao carried substantial development forward. Their names belong together in the project’s history, although their roles were not identical.

That sequence shows why publishing code and inviting help could matter so much in 1997. A motivated outsider could identify a specific visual failure, investigate it, and send back a working change. The original author gained an answer to a problem that might otherwise have stalled the program. Users gained a more convincing game. The technical breakthrough then became evidence for other arcade projects. This is collaboration in its most concrete form: a patch that changes what a player sees.

The collaboration also complicates the popular idea that an emulator’s author is always a single person. Lescot initiated the project and gave it direction. Nao’s patch and subsequent work sustained it. Other contributors supplied knowledge about processors and sound. If one lists only the founder, the reader misses the path by which the emulator became more capable. If one erases the founder, the reader misses the decision to target those boards in the first place. Both contributions can be named without forcing them into a competition.

A specialist alongside MAME

System 16 Emulator developed while MAME was rapidly expanding. They represented different bets. MAME’s framework could add many arcade boards over time; a specialist could concentrate effort on one highly desired family. In early 1997 there was no reason for a Sega fan to assume MAME would soon reproduce every favorite cabinet. Lescot’s program offered a concrete route into games the broad project had not yet mastered. Later overlap between projects should not make the earlier specialist work seem unnecessary.

The hardware itself demanded accuracy beyond an attractive still image. Sega action games could depend on sprite scaling, priority, interrupts, and specific sound-chip behavior. A screenshot of Golden Axe might be impressive while a boss scene still broke. That is why emulator authors talked about individual games and effects, not merely a platform name. Lescot’s project made progress by exposing those details and inviting targeted solutions. The process is less cinematic than the moment a game finally boots, but it explains why the result could improve from one build to the next.

Why his place in the story matters

Lescot did not need to build the largest emulator to leave a mark. He recognized an underserved target, began work before broad arcade emulation had reached it, and made that work public enough for a collaborator to carry it farther. In 1997 the scene needed focused experiments as well as universal ambitions. A project like System 16 Emulator demonstrated that a small team could get close to arcade hardware many players still remembered vividly. It also gave programmers a practical place to test what they thought they knew about those boards.

The record does not offer a detailed private biography, and this page does not invent one. The supported story is his work as ShinobiZ, his role in founding System 16 Emulator, and the partnership that shaped its 1997 development. Those facts are enough to explain why his name should appear beside the emulator, and why the emulator should appear beside MAME in an account of the year’s arcade breakthrough.
