I tried and ChatGPT 5.6 managed to figure out the answer within an hour.

ChatGPT 5.6 helped me to fully reverse engineer save file format for a relatively-known game, and write a working serializer/deserializer to edit in-game currency. Reverse engineering is something I've always wanted to learn but now I am starting to question if it is worth learning manual reverse engineering at this age when AI can do it for us.

What prerequisites I need to solve this puzzle? I don't have much knowledge in electrical engineering.

> To identify this person, the cops contacted Kik, but their subpoena accidentally requested information about the Kik user “fus_ro_dah” (one underscore after “fus”). Kik provided Klayme’s email address in response.

> Google records showed that this email address was used to access Google services from an IP address in Canada, so the Dane County investigators turned the case over to Halifax Regional Police. Halifax police took the IP address they had been given to local Internet provider Bell Aliant. Bell connected the IP address to the physical address of their subscriber, Brandon Klayme.

This is startling to me as it shows how easy to pinpoint exact location based on email alone.

$45 USD is equivalent to about 63 CAD. This is crazy considering that I brought 4GB one last year for $70 CAD.

I attempted the problem myself before reading your solution. My strategy is bit different: for every N>285, I check whether there exists a positive integer solution n to two equations T_N=P_n and T_N=H_n. Using basic algebra and quadratic formula, it boils down to checking whether the quantities 1+12(NN+N) and 1+4(NN+N) are perfect squares. If they are perfect squares, denote their squares by x and y. The next step is to check if 1+x is divisible by 6 and if 1+y is divisible by 4. They are easy using % operator.

    from math import sqrt

    def isPerfectSquare(n):
        sr = int(sqrt(n))
        return sr * sr == n

    for N in range(1, 10000000000):
        foo = 1 + 12*(N*N + N)
        bar = 1 + 4*(N*N + N)
        if isPerfectSquare(foo) and isPerfectSquare(bar):
            x, y = int(sqrt(foo)), int(sqrt(bar))
            if (1+x)%6 == 0 and (1+y)%4 == 0:
                print(f'Candidate found: N={N}, T_N={N*(N+1)/2}')

All I can find is this magnet link: magnet:?xt=urn:btih:brl45s3ysyotj6ljolmtnrlvfmyv4y7s&dn=tea&xl=59368985613&fc=57794 but this is not 200gb one...
