This is where game emulationessentially recreations of an old consoles hardware environment in software formcome into play.
So, how do they work?

Imagine you had a clock, every gear synced in perfect time.
Still, he told us it took him close to five years to reach this point.
Developing the base code of the emulator took relatively little time.

Instead, the spit and polish required to make it playable required most of his and fellow developers effort.
He described the emulation process as akin to any video or image app.
The data is just thatbits of code that need interpretation.

Longtime emulation creator Benjamin Stark, AKA Zodttd, most recently developed theGamma emulatorto play PS1 on iOS.
He told Gizmodo over email that he likened emulation to a conversation between two machines.

An emulator can be seen as an app that creates an AI avatar exactly like them.
Their avatar socializes at the party, with everything said translated back and forth.
Finally, their avatar reads a translated speech to everyone, as if the person were standing there.
Emulating the relatively simple Game Boy is far less complicated than the PlayStation 2.
This would happen at runtime while the software operates.
For more modern devices, many users prefer theSteam Deckfor emulation, and the reason for that is Emudeck.
Not all systems are designed the same at the hardware level, Dragoondorise told Gizmodo over Discord.
Something like the Sega Saturn is especially hard to emulate because of its number of processors.
And then you get into the issues with peripherals.
The user only interacts with the front-end, and the difficulty is getting it as seamless as possible.
For something with 3D graphics, it gets far more complicated.
The difficulty could be getting a modern equipment to comprehend the 3D graphics.
Depending on the platform, you may be developing more for one than another.
Thats a huge step up in complexity, but thats what gets to the modern systems today.
Just How Big is Emulation?
Some consoles are harder to emulate than others.
Most notoriously, emulated games for the Nintendo 64 may show broken textures or effects that ruin the experience.
According to Testut, there may be several hundred emulation developers with big enough names to have a following.
Beyond that, thousands more independent actors are likely offering time and code for these individual projects.
DragoonDorise related it to a FOSSa Free and Open Source Softwaredevelopment utopia.
There are a few legends in emulation development.
He contributed to that project and helped bring it to the iPhonelong before Apple started allowing emulators on iOS.
Its easy to underestimate how big emulation is online.
Then, theres the huge and growing homebrew scene.
For some examples, look toGoodboy Galaxyfor the Game Boy orAlwas Awakeningfor the NES.
Current-day retro-focused companies likeDigital Eclipsemake their living bycreating interactive documentariesof past games.
The company effectively builds emulations of those games by looking at and recreating the games actual ROM.
Those lucky games that get official emulator release are the exception, not the rule.
In some cases, older games are caught up in license hell.
That game only got a rerelease in 2023, despite its enduring popularity.
The passion, instead, comes from those who originally played these games.
The industry is full of developers who got started by emulating or enhancing older titles.
Inevitably, thats bound to cause issues.
Are Emulators Legal?
Many of the largest publishers and console makers have demonized emulation for years.
The game company eventually bought VGS, just to confirm it could shut it down.
Despite this early legal win, game companiesespecially Nintendohavelong-held enmity for emulation.
Last year, Nintendo blocked Gamecube and Wii emulator Dolphin fromcoming to Steam.
They argued that only an incredibly tiny portion of the code was used to get around encryption.
Plus, developers pointed out Dolphin is capable of playing homebrews as well.
Dolphin previously said all it took toextract the keywas some smart engineers and a pair of tweezers.
The developers also agreed to pay $2.4 million for the settlement.
On Oct. 1, Nintendopressured the developersof the Switch emulator Ryujinx to shut down operations.
Nintendo has deep pockets, they have the money to do it, Loiterman said.
Even showing emulation working online can put you in Nintendos crosshairs.
He toldThe Vergethat several of those videos show he physically owns the games hes emulating on camera.
Beyond that, ROMs are a potential legal minefield.
Companies could go after ROM distributors like movie and music companies did in the 2000s against piracy.
That hasnt happened to any significant degree.
Designers arent too worried about their legal future.
Stark and Testut pointed out that Yuzu had to bypass a lot of encryption on the Switch.
The emulation community is the core market of video game companies, centered around nostalgia, Stark said.
Emulation is seen as an act of love by the community for these companies.
Beyond all that, users should feel safe downloading an emulator.
These hardware-to-software environments are fair game so long as they dont contain any ROMs themselves.
However, the games themselves, those ROMs, are direct copies of the original games.
They are breaking copyright, and it is certainly illegal to distribute.
That means any system that comes with pirated ROMs preinstalled is similarly illegal.
Its not close to a full legal shield, but it establishes these programs exist for uses beyond piracy.
Emulators Are More Than Ethical; Theyre Integral for Games Preservation
Books fall apart.
VHS tapes eventually degrade.
Part of that is how games are tied to their original format and individual consoles.
In 2018, Sony released thePlayStation Classic consolethat used the PCSX emulator in its hardware.
Though Atari has released backward-compatible consoles for the2600and7800, few major game makers have gone the same route.
In October, the U.S.
Copyright Officesided with industry groupsrepresenting the games industry against preservationists.
The offices director, Shira Perlmutter, wrote that emulation would implicate copyright owners distribution rights.
Testut said he hopes that there may come a day when emulators are seen as far more legitimate.
That seems like a pipe dream for the vertically integrated publishers and console manufacturers, but one can dream.
Emulator developers spend years creating and perfecting their software.
The community is strong and growing all the time.
There is demand forSuper Mario Sunshinefor the Gamecube.
Morally, its the only way to check that those video games are not lost to time.
News from the future, delivered to your present.
Those who want a console at launch June 5 should get in line as soon as possible.
