This is the project site for the PROPHET64 & MSSIAH SDR Load and Save device (SDr).
The SDr makes it possible to load and save songs, instruments, patterns, patches etc from your favourite C64 music software using the SDR function on a microSD card.
It is the fastest and easiest solution avaliable. It takes less than 14 seconds to load a MSSIAH sequencer song and 17 seconds to save one. A big improvement, compared to a 1541 floppy drive.
The handling is very simple. Just choose a slot and press a button to load or save from/onto that slot.
The provided schematic and software is working fine for me. But :
I take no responsibility for any bugs or damage caused by building or using the SDr !!!
Please keep always in mind that you are dealing with a 25 year old Computer!
