Usually these hacks are always from insiders. Sometimes the entire team plans this months and years ahead.
Particularly for this adventure, I have kept it strictly private. It was a hobby project and also was a challenge to myself.
In the process I learned not only of M32C(backwards compatible with M16C processor module in Ghidra), but as I mentioned, certain compiler bugs(not following the ISA spec strictly) that it is more flexible despite what the M16/M32C software manual says. However this meant that emulation produced wrong results, and thus my patches to fix it and ultimate success
I have opened a Ghidra support ticket, but I needed to provide proof that there is ISA behavior not described in the software manuals.
How did reverse engineering m16c prove challenging? I recently extracted a 4 stage encrypted payload from an M16C arch that also used time-based encryption. Each time it was run, the output was different. The time based key was also rotating.
It used a very simple custom encryption for the time stuff and AES in ECB mode.
Protip Ghidra does not emulate inherent CPU behavior of INDEX instructions, behaviour not specified in ISA. I had to backport M32C instructions and patch M16C slaspec to emulate this behavior, caused by compiler bugs.
I haven't seen any Haruhi references in about as much time yeah, it was insanely popular back in the day.
Haruhi, 4chan, been a while.
It's fixed there, though. I am also in the thread having replied several times when I was working on unicorn.
I was absolutely sure the name was Trek-related. Glad to read I was right.
Garak is by far the most interesting persona in DS9.
About 10 years ago I went to an ophthalmologist. I had experienced a situation which I can only describe as a visual phenomenon traveling from one part of my visual field to beneath it. I was partially blind because of it. I can only think it was a very small stroke or something. They found nothing wrong with my eyes and in passing I mentioned these white things.
Combined with my inability to explain what I saw, the doctor was visibly annoyed and said I need a psychiatrist not an ophthalmologist.
Except, last year electric prices were so high in Europe. As in 10 times higher. If it wasnt for thr government stepping in, our family business would've been decimated.
