Show HN: Wampy, interface addon for Linux-based Walkmans

Wampy is an interface addon for modern Linux-based Walkmans, which allows you to switch between standard interface and custom one using hardware Hold switch.<p>The project was born out of handful of standard UI nitpicks and &quot;can I make a prettier UI?&quot;. There is no Rockbox port for my device (NW-A55), so I did a UI myself, unlocking and adding various features along the way, such as:<p><pre><code> - Winamp 2 skin support - Custom cassette skins - Digital clock skin ported from iPod Nano 7g - Audio amplification table editor for S-Master HX - All audio filters are available regardless of firmware - Per-song audio filter options - Standard interface enhancements (add clock and increase cover art size) - Low latency USB DAC module - FM radio on devices with FM chip and Walkman One (A40&#x2F;50) </code></pre> The result covers 6 models, from cheapest NW-A30 to premium NW-WM1Z. Development process involved a lot of reverse engineering, digging into device internals and was pretty fun overall; there are links to development stories in README.md, describing how this or that feature was added.
