Hello! I'm cyanic, and I mess around with Japanese toys. This account will mostly be for personal interests. I'll also repost the start of teardown threads here, but if you want to follow the full thread, check @teardowns.caralynx.com.

Seriously though, I had to shovel half a foot of snow in the past couple of days, and the forecast says it's going to go below -33°C today.

Finally got some stuff from Japan shipped. For the longest time Japan Post wasn't shipping to Canada. Anyway, it's another Punitapichan, specifically this year's rerelease. I mainly wanted to see if it's got new firmware.

Denuvo's removed on Hi-Fi Rush, I may finally buy it, maybe even at full price.

My #39c3 talk about the Vital Bracelet series is set. Hope to see you there! If you can't make it in person, it'll be streamed as well. fahrplan.events.ccc.de/congress/202...

The Vital Bracelet series, active from 2021 to 2024, was a line of toys that revolved around a number of fitness bracelets that encouraged exercise by raising characters from the Digimon series, and e...

Writing serialization code is exhausting. I just want to package up some graphics and JSON-formatted data, not have to figure out how to arrange all the bits in a particular way.

Queuing for #39c3 tickets is super competitive. You refresh the instant it the minute hand hits zero and you get queued anywhere from 10 minutes to 60 minutes. I got queued at around 18 minutes, and it sold out with 7 minutes left.

Today's item: LeapFrog LeapMove. I saw this last week at Walmart, and this week after visiting the Lab Tama, I decided I might as well pick it up.

I finally bought something non-Tamagotchi. It's a Bitzee Hamster Ball.

I received a virtual prepaid debit card as a part of a promo, and selected to convert it to plastic. In the meantime, I spent it, and apparently they issued the card after that, because they printed a value of $0.00 on the card. Funniest thing I've seen all day.

I tried to turn on my PowerEdge R630 that has been sitting around turned off for like half a year, and it is no longer turning on. Getting a ton of errors about voltage levels and CPU thermal trip when trying to turn it on. I think it might be a system board issue. Anyone got any ideas?

About SNC7320/SNC7330's firmware encryption scheme. Info on how it boots, how it decrypts firmware, and a fun brute forcer for the 32 bits of secrecy it actually has. github.com/GMMan/snc73x...

I spent some time figuring out Ciao Plus' image scrambling algorithm because I wanted to archive the Tamagotchi Manga on it. Let's take a look.

Sprites! The first three monthly brush tests were of Sudo, Banon, and Noko. :D

I made a mod for @crittercove.bsky.social for loading custom skins. The loading part is easy; next step is to figure out how to export the model and texture from the current body parts selection so people can have a reference to work from.

Apparently Visual Studio has used up my monthly GitHub Copilot quota already and I have literally no idea what it used them for. I didn't make any prompts at all inside VS. Maybe I should just turn the whole thing off again because clearly I don't understand the benefit.

A look at SNC7300 bootrom's UART console. It's... a thing. There's a few pieces to it. You can access ISP features if there is no valid firmware, or if you interrupt boot. By default, the baud rate is 115200, but you can also use auto-baud (I haven't calculated the range).

Continued looking through SNC7330's bootrom, and here's a perplexing piece of code that I reconstructed. It's supposed to return the block (or page?) to read the load table from (basically a bad block table), but I'm pretty sure it doesn't actually work.

Looking through SNC7330's bootrom again. Apparently it's using double precision floating point numbers to calculate the settings for UART speed. WTF? Not to mention that they hardcoded the desired rate and system clock speed, so they could have just precalculated and saved a bunch of cycles.
