Description

Machine code can be assembled for custom instruction sets defined by the user. This is useful for emulator projects, fantasy consoles, hardware experiments, and educational CPU designs.

It is a developer tool for people who understand assembly concepts. Incorrect instruction definitions or output files can make firmware, ROMs, or test images unusable.
