Hi, I am Fatafat321 Developer from Elikatta, Telangana, India.
FatafatOS 81 Tiranga Edition - 50MB Pure x86 Operating System for PC and Laptop, Made in India. Built from scratch in Assembly (boot.asm) and C (kernel.c). NOT an Android ROM. It is a desktop OS that boots on real PC, laptop, and Limbo emulator. Built entirely on Android phone using Termux, but runs on PC. Features 50MB ISO, boots in 2 seconds, Tiranga desktop UI, PIN lock, taskbar, custom .fata file format. For low-end laptops and computers.
What is FatafatOS 81?
- 50MB only, boots in 2 seconds
- Built entirely on phone in Termux
- Files: boot.asm, boot.c, kernel.c, kernel.h, linker.ld - all from scratch
- Tiranga theme desktop + PIN Lock + Taskbar
- Own file formats: .fata, .fsw, .fsl
Why I built it?
India has 140 crore people but no own Operating System for PC. That fact hit me hard. So I decided to build one. Fatafat is a pure Indian word meaning fast.
My Journey:
- Started with handwritten 14-page C book
- Learned Assembly + C on phone
- Built bootloader with 55AA signature
- Built kernel in NASM
- Made ISO bootable in VirtualBox & Limbo Emulator
Other Projects:
- 3-Player UNO game with real cards + HTML version with bot referee
- Fatafat321 Official Website (lightweight HTML only)
