8085 emulator implements the instruction set provided by the 8085 microprocessor and allows running assembly programs for that architecture.
8085 emulator is intended to be used as learning resource as it will provide documentation and guide for how to write programs on 8085 instruction set.
- The core emulation is implemented using Rust using this programming manual http://www.nj7p.org/Manuals/PDFs/Intel/9800301C.pdf.
- The UI portion is implemented using React library for Javascript.

$ ./emulator --help
emulator 0.1.0
USAGE:
emulator [OPTIONS] [FILENAME]
ARGS:
<FILENAME> if filename is not passed then the program will run on interpreted mode
OPTIONS:
-a, --assemble pass filename and generate assembly code
-d, --disassemble pass .asm file and disassemble them
-e, --emulate emulate 8085 and write its state and memory values to file
-h, --help Print help information
-i, --interpreted run on interpreted mode
-o, --output <OUTPUT> If output is not provided then the program will assume writing to
stdout
-V, --version Print version information
$ emulator --interpretedto run on interpreted mode
