This one is pretty straightforward if you've already figured out the first and second puzzle of Ruckingenur 2. Insert keycode via the serial pin on the top chip, pulse the lock pin of the bottom chip.



There's one extra solution not pictured which is even more trivial.

This one's actually really fun, so I highly recommend you have a crack at it yourself before reading on.

First off, the objective is lying. There's no way to make chocolate, it's actually asking for coffee (at 70 degrees for 3 seconds).

The idea is that you have to find the right serial pin to intercept the barcode, and try to figure out what each digit means, and then substitute a made up code that gives us what we want. The serial pin we want is the top right one of the 32K chip. For 82 degree coffee dispensed for 2 seconds, the code is BC82020100, for 96 degree tea for 2 seconds it's BC96020200. From this we can deduce the code goes as such:

BC - short for barcode?
82 or 96 - temperature
02 - dispensing time in seconds
0100 or 0200 - coffee/tea identifier

So for 70 degree coffee over 3 seconds we want the following input:

BC70030100

and then let it brew


There's a lot going on with this level, I haven't found any alternate solutions, though. At least you can have some fun making it dispense ice tea.

As a person with no computer science background, Ekoparty's puzzles had me completely stumped at first. The fact that they're entirely built around the idea of brute-forcing your way in doesn't help.

In this one we have to make our way in using an RFID card... Whatever that is. The idea is that we find the keycode via brute-forcing, and then write the code into the card via the debug point.

The auth16 chip reads the keycode via its "serial in" pin, so that's where we want to plug our serial clip and feed it numbers one by one. The moment you stray from the intended combination, the red LED lights up, that's when you have to reset by pulsing auth16's "reset" pin and try again from start. Slowly, digit by digit, with copious resetting, you should arrive at the 5-digit jackpot. Write 3 random digits into the RFID card (the first 3 digits aren't read by the contraption at all) and then the 5-digit keycode.

Click the card to win.


I have no idea what this level was meant to be, which made it kinda boring to me, but I'm sure any computer engineer would find it fascinating.

To be honest, I don't actually know what exactly this is, but the rough idea is that we plug a thing that can spew random combinations into an auth chip and wait a bit while it brute-forces its way in.

What's pretty cool is that the contraption isn't powered at first, so first thing we do is send a high pulse into the VCC pin of both chips (VCC being a power supply-type thing).

Another cool thing is the CRC32 calculator. I don't actually know what that is, but apparently it can generate pseudorandom garbage at a very high rate once we plug it into itself, which is exactly what we need to do. We can do that, because its registries dictate which functions map to which pins. All we have to do is put CLKIDX on the sixth pin, the same one as OUTIDX, then pulse that very same pin to set off the fireworks as it repeatedly keeps setting itself off with its own output, giving us the right code in a matter of seconds, winning us the puzzle automatically.

So you thought we were done with brute-forcing. You poor little person.

At least the premise is pretty cool. We have to hack a nondescript fictional games console to run pirated copies of a nondescript fictional game. Nothing to see here, Nintendo's lawyers.

First off, we have to learn what makes the console accept the legit copy. It's the Security Checker chip. We can't directly hack these values though, we have to use the programmer, and to use the programmer we first need to brute-force our way in. We do this by - hang on to your seats - putting the voltmeter on the EJECT pin of the Tray Controller chip (don't pulse it, though), and checking the voltage for spikes as we try all letters of the alphabet on the serial pin of Security Checker, one by one, for the whole 4-letter combination. At least unlike the first Ekoparty puzzle, there's no need to reset this time, just keep pressing keys until you get the whole password.

Once the message pops up that you're ok to start programming, set BANK02 on the programmer to the DVDFLAG of the pirated copy according to the Security Checker, then hit the Program button.

At this point, you should be able to just insert the pirated copy and win.


There is another, glitched solution to this puzzle which is much simpler, but I'm not gonna describe it in detail. The idea is that you keep the console from spewing out the CD and then kickstart the reading process. Should be easy enough to figure out on your own.
