I don’t use twitter anymore, migrated to Mastodon like everyone else. for my current digital residences

My recent obsessions wouldn’t have translated to a HOPE talk this time around, so I’ll be partying it up late “Saturday” night at HOPE after my friend d3nt and before my new friend dj-spock #digitalhardcore #hopeconf

I'm crazy! 🤪 After @dosnostalgic talked about DOS versions of Wordle, I had to write Bootle: A wordle clone in a boot sector. I could fit only 57 words but c'mon it's the game in 512 bytes!!! https://t.co/CqtT7pbokh #gamedev #retro #retrogaming #wordle cc @XlogicX

The world needs more people that think like this, tragically, we now have one less. He was nothing but good vibes every time our paths crossed. May his inspiration continue to spread, he will be missed.

I'm increasingly thinking that every functioning system has two forms: The abstraction that outsiders are led to believe, and the reality that insiders actually and carefully operate.

You don't incrementally learn a system. You eventually unlearn its necessary lies.

MatchUp is a boot sector game by nullvalue1 from Indiana, USA. It is a memory card game where you select the card with the arrows, and the push Enter to reveal. Very fun game. #gamedev #retro #retrogaming cc @XlogicX https://t.co/7fzZK604TX

Got books from Lulu Press: The Complete Bootrogue Strategy Guide by @XlogicX, and Not All Fairy Tales Have Happy Endings by @caboken both look amazing and I cannot wait to read more! https://t.co/jE9xweEzZW https://t.co/9SPQmLcSpF

[XlogicX @XlogicX]

@BiaSciLab Also, if you want to see some really cool 16bit BIOS assembly, check out some of the boot sector games out there https://t.co/jZOCt9MnPy. Lots of great example code and manageable first project ideas; as you're limited to less than 512 bytes.

[XlogicX @XlogicX]

@BiaSciLab Any specific book in particular? More than anything, get comfy with a debugger (if you haven't already). Linux has GDB and some good profiles, but I also REALLY like EDB (Evans Debugger), it's a GUI one. Glad to hear you're diving into ASM

[XlogicX @XlogicX]

@BiaSciLab @hnapel Here's a few examples I made a while back to take things to 'the next level' https://t.co/OiyKDcccrf, it has some common Linux API PoCs. If instead you're doing ARM, use this: https://t.co/cOY3vYBCVh, there's some LibC examples mixed in that one. Both architectures are great!

[Travis Goodspeed @travisgoodspeed]

This book by @XlogicX explains @nanochess's boot sector Rogue game, with one full page per 32-bit word of the original binary! Does any other reverse engineering book approach that ratio?

[XlogicX @XlogicX]

@nanochess Not like you didn't already have a copy for about half a year ;). Oh, and did I forget to mention that @nanochess wrote the forward to this book!

[XlogicX @XlogicX]

For those that want a physical copy &&|| to support the work that went into it. However...if you'd just like a free pdf, DM me for the details. This is a guide based on a game @nanochess made.

@nanochess There was also a HOPE talk that overlaps a bit of the content: https://t.co/GGs6W0UhXc

[XlogicX @XlogicX]

@nanochess @jdkee super cool! Though my collection is exclusive to games. Although I did just update the collection with one new game (Pong), from https://t.co/xYxPNpC4hF

Full collection: https://t.co/jZOCt9MnPy

[Joe G @GironSec]

This made me think of you @XlogicX
A future talk maybe?

[Óscar Toledo G. @nanochess]

Here is the archived version of the @XlogicX talk about bootGenie, a program to hack boot sector games #gamedev #retro #retrogaming #hopeconf #hopeconf2020 https://t.co/6ND15VcZp2

[XlogicX @XlogicX]

@doctorow @fashiontechguru @hopeconf @CyberpunkFest The MC accidentally introduced me as Cory, and that my reputation preceded me, haha, I'm not that famous, which makes sense, my talk was on boot sector games, not world changing freedom issues. Honest mistake ;). Also, great talk Cory.

[XlogicX @XlogicX]

BTW, the free internet stream of HOPE (starting tomorrow) is https://t.co/WZXNp7pRwu. As a reminder, my talk is tomorrow at 5pm, right after the keynote from Cory Doctorow

[XlogicX @XlogicX]

For those into boot sector gaming or want to see gdb used in really stupid ways, my HOPE 2020 talk is scheduled at 5pm on the first day of @hopeconf (Saturday Jul, 25th). I have a special guest as well! (@nanochess, creator of bootRogue, 2 books dedicated to MBR gaming, and more)

I am posting this everywhere for obvious reasons
