SIDKick pico is an inexpensive dual-SID-replacement without making compromises regarding quality. It also emulates Sound Expander/FM and has a built-in PRG launcher. The new firmware offers the possibility to flash PRGs from disk, adds diagnostics and more paddle configuration options.
There is also a new hardware variant which hosts the microcontroller, flash, DAC, op-amp etc. on a footprint only slightly larger than an original SID chip.
