Atomite FusionSystem

FusionSystem is a self-insert operating system made by FusionDev. It is made by Atomite Softworks. Canonically, it is written in C++, C#, BASIC (pre-1992), Assembly, Python and JavaScript.
== Versions ==
=== FusionSystem (1986) ===
First version of FusionSystem. It wasn't really popular as Atomite wasn't really known in the computer market like Apple, IBM and Commodore were at the time. Had no GUI and had a text-based UI instead.
=== FusionSystem/2 (1988) ===
Successor to the original FusionSystem. This version introduced a GUI, but did not support color graphics at the time. FusionSystem/2 had a bug where it would fail to initialize if the graphics adapter supported color (such as CGA). The bug was patched in FusionSystem/2 Service Patch July 1991. After the patch, the OS would somewhat support colors, but unofficially, the colors being inconsistent throughout the system.
=== FusionSystem/3 (1992) ===
FusionSystem/3 not only added support for color displays, but also revamped the codebase and GUI design, adding icons and porting any BASIC written programs to another programming language like C++ or Python. It removed support for BASIC in general, but it still had a BASIC compatibility mode called "Real Mode", which would allow BASIC programs to run on FusionSystem/3.
=== FusionSystem/4 (1996) ===
FusionSystem/4 introduced the React design language, which was inspired by the Windows 95 user interface design. It was also the first version of FusionSystem to not require a version of DOS to run. If a version of DOS was present in the system, the shutdown window would have an option to reboot into DOS mode. However, if DOS was absent from the system, this option was disabled.
=== FusionSystem/5 (1999) ===
FusionSystem/5 prepared the OS for the Y2K bug, now displaying the year in the 4-digit format (e.g 1999) instead of the 2 digit format (e.g 99). It was extremely popular, as Windows ME had a lot of negative criticism. FusionSystem/5, at its peak, had a market share of around 62.8%.
=== FusionSystem/6 (2002) ===
FusionSystem/6 replaces the React design language with Strontium, based off the Mac OS X style. It also introduced support for WiFi, no longer requiring a telephone line or an Ethernet connection to access the internet.
=== FusionOS/7 (2005) ===
FusionOS/7 was the first version of the OS to not use the FusionSystem branding. It also introduced Vault, a password, ID card and general personal information storage program. It required an Atomite Hello fingerprint or NFC reader, so at the time, Vault was barely used.
=== FusionOS/8 (2008) ===
FusionOS/8 introduced the FusionOS-as-a-service model, making it the first "as-a-service" operating system. It also rebranded to being made for graphic/UI designers, coming with tools like Adobe Illustrator, Photoshop, and Cinema 4D.
=== FusionOS/9 (2012) ===
FusionOS/9 introduced the Colors design theme, which was a flat user interface which Windows 10 was based off of later. During the time of FusionOS/9's release, Atomite's first leak of the Epsilon-18 kernel (SrQ) spread around leak sites.
=== Fusion X (2016) ===
Fusion X was the first version of the system to ditch the "OS/x" branding. It experimented with a "live desktop", integrating the Launch button's contents into the wallpaper/desktop itself. It was toggleable, so most users of Fusion X disabled the feature.
=== Fusion 11 (2021) ===
Fusion 11 removed the "live desktop option", and replaced the built in web-browser with Atomite Horizon, a heavily privacy-based fork of Firefox. Thos version was extremely buggy, however, most due to the unoptimization of the Strontium kernel (the kernel used in Fusion since its original release) for modern systems. It did not fully support TPM, so TPM-based machines had to disable safe boot in the BIOS settings before being able to install the OS.
=== Fusion 12 (2025) ===
Fusion 12 is an upcoming release of Fusion, scheduled for release in March 2025. It is confirmed to have the SrQ kernel, replacing Strontium. SrQ is planned to be an entirely universal kernel, thus making Fusion 12 an operating system that could run on smartphones, tablets, smart TVs, smartwatches and other smart devices as well. It also plans to introduct the Nexite design language, replacing Colors. It will ditch the "Fusion-as-a-service" model, Fusion now receiving periodical service patches instead of twice-a-year feature updates.
