Adding Long File Name Support After building another Arduino based cassette player replacement ,Tapuino for the C64, and seeing how their interface works we have decided that LFN support would be a good idea for the Arduitape. This requires the usage of a different library. At first we'd hoped it would be a simple update of the SDFat library without a code rewrite but as with most projects the simple answer didn't work. I'm now looking into using Arduino-FatFS by Gallegojm which is based on Petit FatFS by ChaN. It may require a code rewrite though. You can find Arduino-FatFS here. https://github.com/gallegojm/Arduino-FatFs
