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.

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?

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.
![Screenshot of C code:
uint32_t boot_load_table_offset_from_bb(const uint32_t *tbl)
{
if ((*tbl & 0xffff) == 0x4242) {
uint16_t count = *tbl >> 16;
for (int i = 0; i < count; ++i) {
uint8_t entry = tbl[i];
for (int j = 0; j < 32; j += 2) {
if ((entry >> j & 0x3) == 1) {
return i * 4 + j;
}
}
}
}
return 0;

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.

Ever since I turned Copilot on on my GitHub account to test something, my Visual Studio has been generating gobs of code, and I'm not sure whether they changed IntelliCode or this is an effect of Copilot being on.

Stupid code found in the runtime for a course produced with Articulate Rise 360. This is not minimized. What's wrong with `arr.indexOf(val) !== -1`?

Let's talk about Sonix SNC73xx's firmware encryption mechanism. It's implemented through the AES block I've previously posted about. In both SNC732x and SNC733/4x the encryption is based on AES-256, but with different modes of operation.

Would you guys be interested if I opened this type of commissions?
I won't open them now but maybe in about a week or two and if I have time as these are very detailed :0
(I'm still thinking about the price but they would be around $85-$95 usd)

I'm looking at an interesting feature in Sonix SNC73xx's AES block. The input key between encryption and decryption are different, and you run a "key generation" step to convert the key as appropriate and copy back to the key input registers before running the decryption.
