Bugs will still be fixed. ------------------------------------------------------------------- Welcome to one of my oldest, largest, and most complex projects I have created, The PRO-SYS Operating System! It is a labor of love that I have been working on for well over 5 years now! For those unfamiliar with this type of project, it basically emulates a frontend computer operating system, or OS, but entirely within scratch. Think of this Scratch page as a little computer, and the project window as the screen. Logically, the green flag would be the power button! Using PRO-SYS should be pretty simple if you have used another common OS before. Here are its features: - Browse and navigate between a selection of web pages using the built-in browser - Use the paint editor to paint in all colors and sizes - View your face on the webcam (PC only) - Perform a wide variety of tasks in the command prompt - Listen to popular tunes in the robust music player - Change the wallpaper, colors, and more in Settings - Receive messages from our team in the message app - Download additional apps in the PROStore Please leave any feedback, bug reports (especially with Calculator), or feature requests in the comments below. It is very appreciated! Feel free to remix!

Please note that the first 3 songs are only demo versions (not the full songs) - Album art: Google images, so they belong to their respective owners - Startup sounds: the numbers in settings refer to the following sounds: 1. Windows 95 2. Windows NT 3. Windows 98 Those sounds belong to Microsoft. - Smooth glide animation script was made by @codoga - Title text in Flappy Airplane is from flamingtext.com - Videos on PROTube come from various sources, mainly YouTube. Check out the respective sprites inside the projects for source video links. - The Word Processor app was created by @griffpatch. The original project can be found here: https://scratch.mit.edu/projects/88564231/ The version in this project uses fixes for Scratch 3 by @MrSqueak https://scratch.mit.edu/projects/293017032/ - Everything else: Me! As for the OS concept itself, It is not based on any 1 system or product, but on a number of various other OSes I have seen. I would, however, like to mention some users that have inspired me: @codoga @-Strife- @-Locked- @Techno-CAT @ScratchcatandGobo and many others (I may add more shoutouts). Check out all their projects! Also inspired by official OSes such as Apple iOS and Microsoft Windows. Also special thanks to @griffpatch for being a great scratcher and inspiring several code changes in this project. **************************Change log********************* The complete PRO-SYS changelog can be found here: https://bit (dot) ly/3qnMMQw _ v2.4.0 | 8/29/25: Added Word Processor app and Notifications, minor Settings and Command Prompt changes, bug fixes. v2.3.2 | 11/2/22: Major home screen animation changes, Command Prompt tweaks, bug fixes. v2.3.1 | 7/13/22: Added shuffle and repeat controls to Music, other minor changes and bug fixes v2.3.0 | 6/9/22: Added clock app, multiple home pages, Fixed major Calculator bugs, Better full screen button, other tweaks and bug fixes. v2.2.3 | 3/26/22: Major bug fixes v2.2.2 | 3/25/22: Added keyboard controls to PROTube and Music, Platformer level changes, other tweaks and bug fixes. v2.2.1 | 2/7/22: Updated home screen rearranging, PROTube improvements, bug fixes. v2.2.0 | 1/25/22: PROTube added to Browser, guest mode now temporarily resets settings, and other minor changes. v2.1.3 | 10/28/21: New URL shortening tool, minor graphical adjustments. v2.1.2 | 9/18/21: Updated Browser webpages, icon and animation adjustments, bug fixes v2.1.1 | 9/11/21: Music app redesign, new song added, bug fixes and other improvements v2.1.0 | 8/16/21: Added Calculator and Flappy Airplane to PROStore, new Paint interface, added collapsible top bar, major bug fixes, and other improvements v2.0.2 | 7/6/21: Paint interface improvements, Command Prompt changes, added Calculator to PROStore (Coming Soon), other tweaks and fixes v2.0.1 | 5/13/21: Fixed and aligned Text and Home Button color settings, minor changes to PROStore, Music, and Platformer, and various bug fixes v2.0.0 | 4/7/21: First shared. * See the 1.4.4 Project for previous change logs (link above) #os #operatingsystem #camera #paint #browser #store #draw #music #command
