JuniEmu is an emulator interface designed for ARM 32-bit.
JuniEmu is using Unicorn framework for emulation, Capstone disassembly framework and Python's standard GUI package - Tkinter.
The goal of the project was to visually emulate (single step, breakpoint, memory view\edit) raw ARM binaries (bootloaders, embedded firmware, standalone functions, etc).
- Single steeping and breakpoint support
- Memory view and edit
- Registers view and edit
- Instruction highlighting
help - print help
d <addr> - dump memory to current view windows e.g.
u <addr> - unassemble address or register e.g.
u 0x1031 (disasm 0x1030 in Thumb mode)
bp <addr> - set breakpoint
bc <addr> - clear breakpoint
bl - list breakpoints
r <register> <value> - change register value e.g.
r r0 0x101
rr - print registers
? - calc expression
dump <addr> <range> "PATH" - dump memory range to a file e.g.
dump 0x1030 100 "/Users/bob/Desktop/dump.bin"
- How to change program counter register to e.g. 0x1030 (ARM mode) ?
r pc 0x1030
- How to change program counter to e.g. 0x1030 (Thumb mode) ?
To switch into thumb mode provide unaligned address (add +1 to the destination address)
r pc 0x1031
- Not tested with Python 3
- Not fully tested on Windows, MacOS
- Input server will freeze the UI until until receiving bytes from the client
