@nina_kali_nina AFAIK Casio did use SuperH in their dictionaries up to DataPlus 7 or so, and some strings in the firmware referenced “PVOS”. It’s relatively recently that they switched to ARM.
@pcy maybe this will be of use https://blog.quarkslab.com/emulating-rh850-architecture-with-unicorn-engine.html
Emulating RH850 architecture with Unicorn Engine - Quarkslab's blog
Analyzing an automotive ECU firmware is sometimes quite challenging, especially when you cannot emulate some of its most interesting functions to find vulnerabilities, like ECUs based on Renesas RH850 system-on-chips. This article details how we managed to add support for this specific architecture into Unicorn Engine, the various challenges we faced and how we successfully used this work to emulate and analyze a specific function during an assignment.
@pcy NEC had one called SM850, still available from https://www.renesas.com/en/software-tool/pm
There was also a V850 model for OVPsim, but not sure if it’s still available after Imperas got acquired by Synopsys.
Graham Sutherland / PolynomialAnna's Archive backed up Spotify. They got 99.9% of metadata, and 300TB of music representing 86 million tracks - original 160kbps OGG for tracks with popularity>0, and re-encoded 75kbps for popularity=0. absolutely wild project.
the metadata in particular is a hugely useful data source. MusicBrainz catalogues 5 million unique ISRCs (like ISBNs but for music releases), whereas this archive has a whopping 186 million.
Backing up Spotify
We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of listens.
mahalozDo LLMs actually help hackers reverse engineer and understand the software they want to exploit?
We ran the first fine-grained human study of LLMs + reverse engineering.
To appear at NDSS 2026.

Jason ScottI have an opportunity for an incredible leap in digitization capability for $1000. If I can get $1000 by one or multiple people, a process that is planned for years will spike downward to a huge degree. Sorry to be mysterious. Email me if you have a sack of cash you want to do something very good.
