The GBA was region free, but Nintendo was region locking their consoles from the start. For example, the n64 is capable of playing games from any region, but the Japanese games had different tabs, and wouldn’t fit in a US console without modding the slot.

Well good news, you can still do bluetooth on a phone that has a headphone jack.

And it wasn’t made to be repairable.

And wireless earbuds are? How many earbud batteries crap out after less than a year? I really don’t think jamming tiny lithium batteries into everything is the more sustainable option here.
