I just observed some sketchy marketing practices from Nintendo.
Here's a few items I viewed a few weeks ago, as displayed on Nintendo Store (US):
...except I logged out and cleared cookies many times in the meantime:
I ruled out fingerprinting as I remembered that I logged in to My Nintendo earlier today for free Platinum Coins, but the problem is that I logged out and haven't viewed those items today. (I re-tested and these items don't appear in a fresh private session.)
Like, seriously? They're incorporating marketing tactics used by broke and desperate companies. Is it really so important to try and squeeze every last cent that you have to track users even after logging out?
I saw someone selling a DS dev cartridge on eBay today, it seems to be PokePark Fishing Rally DS(2005).
(But isn't this DS flashcard from a later version? I think this ROM was written afterward.)
EDIT: The note for DS dev cart SP512M says: IS-NITRO-WRITER must be v1.12 or above, and IS-NITRO-DEBUGGER must be v1.59 or above. The firmware for these two versions were released around mid-2005. Matches the release time of PokePark Fishing Rally DS.
