Don’t be afraid to reinvent the wheel. You never know what crazy, wild path it might roll you down to.
Of course, don’t disregard the works of others – study their work and reuse where you see fit. Don’t reinvent the wheel out of distrust or ignorance of the work of others. - HN

I originally built this as part of a video game decompilation project, having rejected the matching decompilation process used by the community at large. I still needed a way to divide and conquer the problem, which is how I got the funny idea of dividing programs. That allows a particular style of decompilation project I call Ship of Theseus: reimplementing chunks of a program one piece at a time and letting the linker stitch everything back together at every step, until you’ve replaced all the original binary code with reimplemented source code.
