    While I'm still a fan of Unocorn engine, So far I've found that UC does not have M68K support for dbf, not, eor, addi, addq, and logical shift instructions and interpets atleast one move mode incorrectly. I'm going to take a guess and say that no one is using Unicorn for M68K..

    I want a library that takes a M68000 instruction and simply returns the number of cycles it would take to execute on real hardware. This would compliment Unicorn engine nicely and allow you to use a code hook to keep an accurate cycle count for SG/SMD emulation.

    IMO, the author of the vulnerable code should have the final say on the name of their bug and be cited in publications alongside the disclosing researcher. It really is a symbiotic relationship. 🙃

    Genuinely curious about the recent fascination with tiling window managers. i3, awesome, and dwm have been around for 10+ years. Why now? 🤔

    bnida now supports IDA Pro's (7.4) and Binary Ninja's Python 3 APIs: Just improving structure support before I tag a new release. Here's bnida being used to import DWARF info into BN (from IDA):

    Used Python 3 (IDA 7.4). Seems they changed some APIs. idc.MakeCode doesn't exist any longer. You use ida_funcs.add_func or ida_auto.auto_make_code.

    Updates from the flash dump acquired here: I have the splash screen and what I assume to be the loader for the MK Rom partially booting. There are 7 other full ROMs in here as well that all boot. More to come soon!

    Today we released Hashashin, a tool which combines basic block & graph aware hashing to allow porting annotations from one binary to another. Part 2 of our blog series shares the design decisions, where to get it on , & how to use it:

    Back fuzzing emulators with retrofuzz. This time I ran it overnight against Kega Fusion. It produced many crashes (same bug so far). Potentially useful OOB read.

    And the fuzzer works. Reproducible stack overflow in BlastEm.
