CHIP-8 Virtual Machine\n\nANSI C implementation of a CHIP-8 emulator.\nThis project emulates the original CHIP-8 environment, allowing you to load and\nrun classic CHIP-8 ROMs directly in the browser.\n\nCHIP-8 is often considered a rite of passage in emulator development\ndue to its simplicity and well-documented instruction set.\n\n\u003e [!WARNING]\n\u003e ROMs are not incuded in this repository and should be obtained legally.\n\n## Features\n\n* Full CHIP-8 CPU emulation (opcodes, registers, memory, stack)\n* Keyboard input mapping for modern keyboards\n* Browser-based execution (no installation required)\n\n## Keyboard Mapping\n\nCHIP-8 originally used a 16-key hexadecimal keypad.\nThis project maps it to a standard keyboard layout:\n\n```\nOriginal CHIP-8        Mapped Keyboard\n1 2 3 C                1 2 3 4\n4 5 6 D                Q W E R\n7 8 9 E                A S D F\nA 0 B F                Z X C V\n```\n\n## UI \u0026 Assets\n\nOnline website uses:\n\n*
