On the JD-990, it should be possible to change the patch addresses to write to the RAM card instead of internal memory by using address offset 0A 00 00 00 instead of 06 00 00 00. Sadly the JD-800 doesn't seem to expose the memory card RAM area the same way, so I have no way of actually testing this.
