A modified network radio player!

During Children's Day, a food delivery app and several fast-food chains ran a promotion where customers who spent over 61 yuan could redeem a mini radio toy.
These toys were so cute and fun, including a limited edition Snow King version, that I didn't hesitate to participate. I ended up with three radio toys that could record and play audio.
Although they could only record for 15 seconds before playing back, the casing was quite nicely made, felt good in the hand, and the colors were attractive. Plus, the radio's shape inexplicably resembled a Poké Ball radio I'd made before. So, to make the most of the casing, I decided to disassemble it and modify it into a network radio.
The firmware for this modification came from YoRadio, an open-source project by a Russian DIY enthusiast. It only required adjusting the screen resolution and driver to adapt to various hardware.
