Over the past week, I've learned way too much about late 70s computers, CP/M and the various 5.25' floppy formats (hard sectored for the North Star Horizon).
I'm ready for trivia night.

Oh boy, yeah that was IRC I think
I did most of the interviewing for this piece over IRC, if memory serves.
Some early weekend reading plucked from the archives: my 2012 Ars Technica feature on the first 10 years of ScummVM. arstechnica.com/gaming/2012/...

I had to read the theadline a couple times. A vulkan extension to improve directX on linux kinda required to mental gymnastics to parse.
It does make sense in the context of dxvk and all, but it does sound weird at face value

Published RadViewer to visualize the old RAD files from Atari/Tengen

It's been pretty annoying to look at old RAD files through Dosbox, so made a modern viewer for windows.

What fascinates me in that stuff is the glimpse we get into how game development worked in the early 90s.
For example, they didn't really generate fully formed roms, but just loaded all the compiled bits in a dev cartridge. If they needed a rom back, they would just read that back.

Beyond sharing files, information and documentation is one of the greatest resources, especially as a non-programmer. Using the information shared (and info I previously shared), it was easy enough to get later versions running now, this one from 03-05. In an earlier build, the ladder sort-of worked

Folks at @gamehistoryorg.bsky.social received a hard-drive image of a VAX machine. Sadly, the disk had been mostly wiped and only showed up an empty folder.
I went back to the 70s VAX filesystem specs and wrote a tool to reassemble as much as possible of the files. We got some cool roms out of it.

Spent some fun time the last few weeks getting some old NES source code of Police Academy back into a compliable state. Fun dive into the the early 90s development system and all that stuff.
Code and instructions on how to build it I wrote are released today by

Some fun results of the data recovery I’ve been poking around recently. Given how mangled the disk was, we’re lucky to have something like that come out of it
I have recovered a very janky video game prototype from the deleted sectors of a hard drive and I'm going to post a screenshot here to see if any of you fellow sickos recognize it, even though it was never actually announced and this is the first time anyone has seen it (I know what it is, do YOU?).

Mission accomplished at the last minute!
My goal for the break is to finish Persona 3 Reloaded DLC. I'm close to the end (I think), but I probably need to grind quite a bit more... :(

I’m hoping we have a tight enough scene that if someone spots this stuff for sale we can catch these shitheads
KIRO 7 ran an article and two TV pieces on the theft of a box truck full of arcade PCBs, artwork, and machines from my workplace yesterday. If anyone in the Seattle area sees someone offloading a ton of CPS2/NAOMI/Neo Geo PCBs, stuff of that nature, please reach out.
