This is Furrtek’s NeoGeo CD SD Loader. The kit includes a NGCD SD Loader main board (rev E), an assembled microSD board, a flex ribbon cable and a connector to plug CDDA into the board. The kit comes assembled with very a tight PLCC68 socket so that connectivity problems are no longer an issue.
The price reflects the difficulty and higher prices I encountered to source ICs for this project. If prices go down in the future (provided that I make future batches) prices should decrease accordingly.

Thanks to Furrtek for designing this great piece of kit and for making it available https://github.com/furrtek/NeoCDSDLoader
