Several players on one PC is free, with no account. Across PCs, Premium brings ROM Mode, which synchronizes gameplay inputs on 9 systems while each player runs the game locally; Link Cable for Game Boy, Game Boy Color and Game Boy Advance; Stream Mode; and LAN or direct-IP sessions. PS1 and N64 support two-player Native Multiplayer. Not every system supports every mode; the core matrix defines the scope.
Explore MultiplayerOnline, LAN and direct IP.
ROM Mode runs the game on each PC and synchronizes the players on 9 systems; PS1 and N64 support two players. Link Cable connects Game Boy, Game Boy Color and Game Boy Advance games. Online sessions need Premium for everyone taking part.
The right mode for your game.
Not every system supports every mode. 10 included systems play on one PC only. Network setup and title compatibility can affect sessions.

Supported: owner acceptance is recorded for the core or named play mode; compatibility remains title-dependent. Beta: included, broader qualification continues. Experimental: included with limited coverage. In development: no first-party core ships in this release. Optimized: a specific owner-accepted optimization milestone exists. Unrated: no comparable per-core performance rating is claimed. Save states are for local sessions; coordinated multiplayer has its own state policy.
Output scaling and filters enhance the displayed image; internal HD rendering is listed separately for PS1 and N64. Cheats use codes you enter yourself — there is no built-in cheat list — and are switched off in online multiplayer. Rewind is not integrated with these first-party cores in this preview.
Also included: PC / DOS (RazorPC). A bundled MS-DOS 2.0 historical reference environment. It starts at the DOS prompt, and Ultimate Emulator includes everything it needs. It is not a game platform: there is no game library. No sound, mouse, hard disk or save states.

A few things to know
Good questions.
Is Ultimate Emulator free?
Yes. Download, install, local emulation, your local library, saves, supported save states, cheats, controllers, graphics settings and built-in updates are free. No account is required.
Do I need an account?
No account is needed to download, update or use the local application. An optional free Deep Sky Creations account carries your profile into connected account features. Creating an account does not mean purchasing Premium.
Are games included?
Ultimate Emulator does not include commercial games, ROMs, BIOS files or console firmware. You provide your own legally obtained games and, where a system needs it, firmware from hardware you own.
Do I need BIOS or firmware?
Odyssey², Intellivision, ColecoVision, Atari 5200, Atari 7800, Atari Lynx, PlayStation and Game Boy Advance require firmware you provide. Intellivision needs EXEC and GROM. Some Super Nintendo enhancement-chip titles also need firmware; every other Super Nintendo game needs nothing. The in-app Firmware & BIOS center explains the requirements.
Which systems are supported?
The core matrix lists the 19 included game systems, their first-party cores and their current status. PC / DOS is also included, as a historical reference environment rather than a game system. Rows marked In development do not ship as first-party runtimes in this preview. Compatibility varies by game.
Does multiplayer work on every system?
No. Several players on one PC is free and needs no account, and Atari Lynx and Game Gear can also link two consoles on one PC. Everything across PCs needs Premium for every player — online, LAN and direct IP. ROM Mode covers Atari 2600, NES, Game Boy, Genesis, SNES, PlayStation, N64, Game Boy Color and Game Boy Advance; Link Cable covers Game Boy, Game Boy Color and Game Boy Advance. PS1 and N64 have owner-accepted two-player Native Multiplayer. The other included systems play on one PC only, and Game Boy Advance cannot link two consoles on one PC. Multiplayer organizes supported sessions; it does not make unsupported cores compatible.
Are updates free?
Yes. Public Stable updates are free, without an account or Premium. The installed application checks for approved signed releases automatically (you can turn this off), then offers Update & Restart or Later, so you choose when to download and install. Downloads are verified before they are installed. Your library, settings and saves are stored separately from the application.
What is Workshop?
Workshop is the projects, patching and research area, and the whole of it is part of Premium. Without Premium it is locked. When Premium ends, Workshop closes and hosted Workshop rooms end; your local project files are not deleted. Hosted community publishing and cloud synchronization remain in development. Workshop is for mods, patches, mod packs, configuration packs and compatible user-created enhancements. Deep Sky does not distribute commercial ROMs.
Are Cloud Saves available?
No. Cloud Saves are Coming Soon for the Premium connected-services membership. Local saves and supported save states are available now and remain free.
Are cheats and rewind available?
Cheats are free on NES, Game Boy, Genesis, SNES, PlayStation, N64, Game Boy Color and Game Boy Advance. You enter your own codes from the Game Menu; there is no built-in cheat list, and cheats are switched off in online multiplayer sessions. Rewind is not integrated with the included first-party Razor cores in this preview. Save states are available for local sessions on supporting cores; Odyssey², Intellivision, ColecoVision, Atari 5200, SG-1000, Master System, Atari 7800, Atari Lynx and Game Gear do not support them.
Why might Windows show SmartScreen?
Ultimate Emulator releases are digitally signed by Deep Sky Creations LLC. During early public releases, Windows SmartScreen may show an unfamiliar-app warning while reputation builds. Verify that Windows shows Deep Sky Creations LLC as Publisher. If the publisher differs, do not run that file. Keep Windows security protections enabled.
How do I add my games?
Add your legally obtained game folders with Add Games, or in Settings → Library → Game Folders. The application organizes your content by system. No games or firmware are supplied.
Which platform does it run on?
The public preview is for Windows 10 and Windows 11, 64-bit (x64). The installer is signed by Deep Sky Creations LLC and asks you to accept the license agreement. Nintendo 64 uses a Vulkan-capable GPU for its higher internal resolutions and otherwise renders in software at native resolution.
