Speaking of Virtual Boy, here's a clip from a Video Boy VUE, a tool from Intelligent Systems for showing Virtual Boy games on a TV or monitor. In 2021 I wrote up an article examining the hardware: hcs64.com/video-boy-vue/

Still have CRC32 on the mind. Here's something I've been thinking about for a while, correct a single byte error using CRC, checking with MD5 since these collide often with larger files: github.com/hcs64/crc-flip
Finally got the algorithm simplified, mostly publishing to get it out of my head.

Turns out I was half right. And less than half wrong.

Did you know that in 1987 Enix made a Zelda-like with a Buddhist theme? In this episode I attempt to play through this one and find out whether it's a hidden gem or just another dud.

I was asked about using crc32 to identify files corrupted with initial zero bytes, since I'd written crctrunc back in 2019 to (slowly) match zeroes at the end. I finally got around to it, here's crc-init-trunc. As a bonus it's also vastly faster at crctrunc's job.

It's been 30 years since the launch of CD Extra! These audio CDs have special features for computers, hidden from CD players in a 2nd session.
Initially it was called "CD Plus", as in this mid-1995 Sony demo. The name was soon changed, but the Blue Book standard kept a CDPLUS directory for metadata.
