The only downside if you buy electronics with batteries: Buyee strictly enforces a maximum 2 batteries per package rule. So for example a Nintendo Switch would be shipped in 2 package because it has 3 batteries, 1 in the tablet, and 1 in each joycon. Have to plan around that when buying multiple electronics https://faq.buyee.jp/article/99?lang=en (look for items without battery, “unit only” etc)
But, yeah, I found it interesting that literally all used listings in Japan are marked as "junk", I figured this must either be some translation thing, or a trick for seller to avoid returns etc.
Of course buying old stuff requires some ability to do simple repairs. That’s part of the fun.
I think it depends on how much it's been parted up. A big mess of everything is probably safer than a listing of 15 identical items.
However, the seller either didn't know or hid an issue. Zenmarket provided 0 support. I think they just google-translated my message, forwarded it to the seller, the seller just said "item as-is, no partial refunds", and Zenmarket just closed the issue.
For the guitar nerds: the neck was back-bowed, and it was not really playable because several frets were already buzzing. Truss rod arrived completely loose, meaning fixing this would be difficult/expensive. Try to explain to a tired customer support person that it makes some kind of sound, but not the right kind.
I just wish I started getting into software earlier, at that time it felt something super hard for “A beautiful mind” people
WIth a custom CFW you OFC could play Nethack at 50MHZ (With a MIPS CPU even 25MHZ would suffice), where I was more hooked than with Castlevanias...
Oh, and Scummvm, too with Broken Sword, Future Wars and the like. And ScummVM still makes releases so you can totally play Blade Runner in a PSP (and far more).
Now, downvote away.
