Hugsy has created cemu, the Cheap EMUlator that shellcoders will enjoy:
Cheap EMUlator is a simple tool to combine together all the features of Keystone, Unicorn and Capstone engines in a Qt powered GUI. It allows to test binary samples, check your shellcodes or even simply learn how to write assembly code, all of this for the following architectures:
x86-32 / x86-64
Arm / AArch64
MIPS / MIPS64
SPARC / SPARC64
(more to come)
Pre-Requisites:
unicorn and its Python bindings, as the emulation engine
keystone and its Python bindings, as the assembly engine
capstone and its Python bindings, as the disassembly engine
PyQt5 for the GUI
pygments for the text colorization
