If you're a game studio looking for security audits/pen-testing of your game HMU. Experienced with: .- RCE on Windows and gaming consoles.- Windows security internals.- Compiling old/legacy code bases. I'll also accept Japan working visa sponsorship or gacha pulls as payment.
- kernel level anticheat.- games never been SAST scanned, no ssdlc, no security tooling nor budget.- bespoke pipelines built by a single wizard (vanished into the nether).- no appetite to fix findings .- some game devs have astronomically big egos and say things like “remove the.

Small Prometheus update: I finally have the UI done for Halo 2 MCC -> Xbox tag conversions and worked through most of the shader conversion issues. It's still experimental but I plan on getting a canary build out soon for people to test

Game hackers have been copying the homework of malware devs for the past 10 years, but sure whatever you think.
Game hackers have defined the bleeding edge of low-level security innovation for the past 10 years. Infosec will never give us the respect we deserve, but for the people who actually follow our tutorials, it has a profound impact on their lives.

My vision is declining at such a rapid rate that I feel like I'm on a speed run to reaching legally blind status and will achieve it in less than 10 years at the rate I'm going.

On today's episode of who the fuck is using all my VRAM we have Discord with ~2TB of leaked memory. Amazing, incredible even.

I guess they think people are using windows kernel EoPs to try and cheat/bypass anti-cheat? Not a bad idea but I feel like it'd be much easier to just go custom hypervisor route than to write new EoP entries every few months.

Tried playing Apex for the first time in years and kept getting this anti-cheat message. Pretty vanilla windows install, no sketchy drivers/software installed, stock hv, etc etc. It was because I didn't have the latest windows updates installed, like they couldn't just say that💀

So between Unity 2023 and Unity 6 the "drag" field on the rigidbody component got renamed to "linear dampening" and when you upgrade a project Unity discards the old value and replaces it with a default value of 1. Wasted a ton of time debugging this. .

The side of game dev they don't tell you about. Probably gonna have to bust out TTD for this one, but I'm still not sure I even want to follow this rabbit hole to the end. Might just try and create a poc project and open a Unity support case instead

It's 4am and I'm diff'ing two versions of Unity in IDA to figure out a physics change they introduced that broke my crappy car physics code. I'm starting to see the value in being able to access engine source code for unreal. .

I don't have anything against Arcade1Up but for me it's the real deal, Mister cade, or nothing. Anyways, marked that as spam and moved on.

Got an interesting email on behalf of Arcade1Up offering a YouTube sponsorship deal that seemed phishy. The email domain was "ahalabventureunitylaunch .com" (sus) which was created on 4/25/2025 (sus). The email also contained some unsubscribe links (sus) which pointed to. .

Maybe I don't fully understand the tech here, but if you have DLSS upscaling + frame gen enabled, doesn't that mean you're both rendering at a lower resolution and upscaling but also generating fake frames at the same time? And 12fps on a 3080 is the best that can do?.

Unreal engine strikes again. Here we have DLSS upscaling and frame gen fighting for their life to deliver 12 FPS on a 3080 while 3 ghost images of my car follow behind me. In typical Unreal fashion changing the graphics settings in-game doesn't seem to do anything.

Unity shaders are the worst, every version breaks things in the render pipeline and you have to fix by hand. Upgraded to Unity 6 and creating a new shader using their template code with 0 changes is broken out of the box 🤦♂️ I’m so close to switching to Unreal….

This would've been a dream job for me and perfect for my skill set. Unfortunately I'm on to bigger things now and I don't think the Xbox team likes me much after disclosing the BadUpdate exploit😅This would be an awesome position for anyone interested in this type of tech.
Are you passionate about game preservation? Want to tackle some of the hardest engineering problems while enabling new generations to play games from the past? . A great new role just opened up in one of my favorite teams here in Xbox. More Details Here:.

Fantasy RPG games come in 3 varieties: souls-like, turn based, or elder scrolls. Since I don't like souls or turn based I'm basically left with elder scrolls, and Oblivion has been such a "breath of fresh air" even though it's a remaster and I played the original 5+ times.
