I was quite impressed that a regular 8 Mhz Atari 520STFM could do such a decent job of playing SID files. It's definitely not 100% accurate but you can make the tunes out well enough.
To record this video I used an Atari 520STFM connected into a LiNKFOR SCART to HDMI converter using a Exxos RGB to SCART cable which was plugged into a MacroSilicon USB HDMI video capture adapter and recorded with cheese under Debian 12.
I would love to see someone write a SID player for the Uzebox. If the Atari ST can play SID files then I reckon the Uzebox should be able to handle it too.
