So it's already known that Pokemon Bank was made free-to-use by just giving everyone quadruple-digit free "trial" periods. Because the space to display the number of days remaining only holds 3 digits, this showed up as "?40 days" yesterday and "?39 days" yesterday, implying that internally it's something like 1039 or 1139/etc. days left.

The question is: Is it possible to datamine what number is actually being displayed?

I tried making some wild guesses with Luma3DS -> Rosalina -> `turtle` process (Bank's codename) -> RAM dump, but both of my attempts failed:
  • I took some RAM dumps yesterday and some RAM dumps today. Then I brute force searched for all addresses that were the same per day, but decreased by 1 when the day changed. This returned no results.
  • I looked at every group of 4 bytes in the first dump, converted to decimal (little endian), and kept everything that ended in ...40. Then I threw out everything that stayed the same when the day changed. This returned no results (i.e. everything that ended in 40 still ends in 40 today). I also tried the same with groups of 2 bytes instead (same outcome).
By "yesterday" and "today", I specifically mean "when Bank said ?40" and "when Bank said ?39", so no time zone shenanigans.

It is free to use now so you can ignore that.

I know the official support page said that it will cycle from "?99" down to "?00" and restart, meaning that everyone's just been given a four-digit-long free trial. I'm trying to figure out how long, internally, this free trial is set to be.

Consulting an ASCII table, it goes "9 : ; < = > ?", so presumably ? 15, meaning ?40 is 1,540.

This would only work if "?00" changes to ">99" instead of "?99" in 40 days, which doesn't match the official support page. There have been other instances in Pokemon where trying to display too many digits in an available space just turns the extra digits into "?".

    I rather enjoy a life of taking it easy. I haven't reached that life yet though.

    @K3Nv2, RIP Felix does great videos on the PS3 yellow-light-of-death.
  • Jayro @ Jayro:
    Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.

    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

    It's a DS Lite in a slightly bigger DS Lite shell.

    It's not a Nintendo / iQue official product, it's a 3rd party custom.

    Nothing special about it other than it's more comfortable than the Lite

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme

    but that's a long shot

    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."
