Funded within 5 minutes, soulscircuit are clearly onto a winner here with their upcoming Pilet open source modular mini computers powered by the Raspberry Pi 5.
Just to add to what others are saying, check out The Phawx on YT, reviewing these things is kind of his schtick (not Linux focused, retro handheld focused).
By outright piracy ofc. They include a shoddy SD card full of ROMs, but you can and should use your own card (for longevity) with your own ROMs (for legal reasons...)
Oh wow. Their website says theyve been operating since 2019 or something so I assumed they had something going that stopped them from being shutdown by Nintendo.
