  • x64dbg

    An open-source user mode debugger for Windows. Optimized for reverse engineering and malware analysis.

    Project mention: Too Many Fonts in Windows 10 Can Cause Slow Application Starts | news.ycombinator.com | 2023-08-17

    I have never heard anyone say anything good about the Visual Studio debugger before. Now, I'm not a Windows person but I'm not gonna argue for gdb or lldb here. RemedyBG and x64dbg are the two debuggers I've heard good things about though I've never used them because, again, not a Windows person.

    Project mention: If you're interested in eye-tracking, I'm interested in funding you | news.ycombinator.com | 2023-08-26

    Okay, so, your comment about a "Dasher + Guitar Hero music theory/improvisation practice program" just sent me down a huge rabbit hole...

    Well, rabbit hole(s) plural, I guess, most not directly related. :D

    Largely because I made the "mistake" of looking at your HN profile & discovering you're also in NZ & we seem to have somewhat overlapping interests (and an affinity for "bacon" in account names, apparently), so, some thoughts[0]... :)

    # Topic 1: Nissan Leaf VSP hacking

    After reading your recent posts (https://ianrrees.github.io//2023/07/03/vsp-hacking.html & https://ianrrees.github.io//2023/08/05/voltage-glitch-inject...) on this topic & noting your remark about wanting to try reverse engineering a firmware image, I found the following thesis PDF (via a brief google search for `"reverse engineer" "firmware" "Renesas"`):

    * "AUTOMOTIVE FIRMWARE EXTRACTION AND ANALYSIS TECHNIQUES" by Jan Van den Herrewegen https://etheses.bham.ac.uk/id/eprint/11516/1/VandenHerrewege...

    Not really what I was anticipating finding but seems relevant to your interests--I don't think it was already in your resource list.

    While the thesis addresses the Renesas 78K0 rather than the Renesas 78K0R, from a brief look at the "Flash Protection" PDF Application Note in your resource list it seems there's a large overlap.

    Perhaps most significantly the author presents "novel methods" that combine bootloader binary analysis with constraint-based power glitching in an effort to improve on the results described in "Shaping the Glitch".

    While I haven't read the entire 186 pages :D they theorize that using their approach extracting 8kB firmware might only take ~10 hours.

    And, most helpfully, they even published their source code under the GPL here: https://github.com/janvdherrewegen/bootl-attacks

    So, an interesting adjacent read even if it turns out not to be directly applicable to your situation.

    Given I have an interest in & a little experience with firmware reversing my original thought was to maybe provide some hopefully helpful references that more generically related to firmware reversing but more specific is good too, I guess. :)

    In terms of reverse engineering tooling, I've used Rizin/Cutter/radare2 previously: https://rizin.re https://cutter.re

    On the CAN tooling/info front, you might be interested in taking a look at my "Adequate CAN" list which I originally wrote-up for a client a couple years ago: https://gitlab.com/RancidBacon/adequate-can

    Some other probably outdated reverse engineering tooling links of mine: https://web.archive.org/web/20200119074540/http://www.labrad...

    In terms of how to approach RE, other than just "getting started & digging in" & learning by doing, I've sometimes found it informative to read other people's firmware reverse engineering write-ups to learn about potentially useful approaches/tools.

    Anyway, hopefully some of this is helpful!

    [0] I have a tendency to be a little... "verbose" and/or "thorough" (depending on one's POV :) ) so I'll probably split this over a couple of comments, in case I run out of steam while writing and for topic separation.

  • Virtual-Jaguar-Rx

    Virtual Jaguar, an Atari Jaguar emulator, with integrated debugger

    Project mention: New Jag Emulator is out! BigPEmu promises 100% compatibility! | /r/AtariJaguar | 2022-12-02

    Virtual Jaguar (and the newer Rx fork which is actively maintained but weirdly nuked the original repo's commit history) exists and the times I've looked through the source the emulation is based on a reading of the netlists for the actual production parts. Main issues from my understanding are that the bus timings are completely off (so things like T2K run much faster than they should, although it's kind of better that way except in the second bonus stage which becomes impossible) and a few deficiencies in the custom chip implementations. But it's at least 70% there just with development on the emulation logic stalled for about five years.
