Kicking off a 4-part deep dive into AFD.sys on Windows 11: crafting a raw TCP socket, performing the TCP handshake, sending & receiving TCP packets - everything without Winsock.

Yo all, it is Friday now where I am, so might as well get the #nakeddiefriday thing going.

Today's guest is the famous NES PPU chip, RP2C07A by Ricoh. What's interesting about this particular sample is that it's very very dead. Many thanks to @root42 for supplying it!

As always, a short thread follows. Why not give this one a boost while you're here? :D

SiPron page for those hi-res maps we all love: https://siliconpr0n.org/archive/doku.php?id=infosecdj:ricoh:rp2c07a

Note the die is oriented the same way Visual 2C02 has it: https://www.nesdev.org/wiki/Visual_2C02

My latest blog post: Reverse Engineering a Broken Night Light - Part 1 - Tear Down

https://mikecoats.com/night-light-part-1/

We bought our first Night Light when our daughter was born; within 3 years, it and its replacement had broken. Let's tear it down, reverse-engineer what's left, and build it back up with some extra 'smart' features.

Hey, hi, hello!

mx here - geek, nerd, jack of many trades (master of none, obviously). Art and design, programming, hacking, reverse engineering, music.

Here mostly for the type and lettering, and to get first-hand fediverse experience.

Attached is a quick digital sketch to commemorate my overdue "some time lurker, first time poster" moment :)

Dites les gens, connaissez-vous un site qui référence tout les protocoles réseaux/radio/etc propriétaire que des gens auraient rétro-ingénierié ou libre (genre les RFC mais pas que). Si ça n'existe pas, c'est parce que c'est pas légal de faire ça pour la partie proprio?
Je sais pas trop ce qui est légal ou non là dedans et je trouve dommage qu'on ait ça quelque part. Chacun fait des trucs dans son coin mais rien de "centralisé" du moins que je sache.
