April Fool’s Day isn’t just for pranks anymore! In a delightful twist, Rockbox 4.0 has officially dropped, proving that this legendary MP3 firmware is far from outdated. After a lengthy hiatus, it’s exhilarating to see Rockbox making waves once again, reminding us of its cherished past.

For nearly two decades, Rockbox has been at the heart of the personal media player (PMP) hacking scene. If you remember the excitement surrounding those old-school MP3 players, you’ll appreciate the nostalgia that this release brings.

Curious about which devices can still run Rockbox? We reached out to prominent Rockbox contributor Solomon Peachy, who informed us that the AIGO EROS Q and EROS K are currently the only models in production that support this firmware. For the rest of us eager fans, it looks like the second-hand market is your best bet—hit up eBay or similar sites to grab compatible devices.

For the tech enthusiasts out there, be sure to check out the Rockbox Wiki for an updated list of supported hardware. It’s exciting to think about the potential for reviving old tech—Rockbox is here to keep the music playing!
