Hi,
either me, I tryed to modify it => I confirm you this do not work.
And I had read somexhere in the forum that the S1RES software is currently not available for this firmware...
For the moment I just can extract may Firmware with S1FXW software...
I made it to obtain a save of it.
I just hope & pray for that to upload back the firmware will be possible the day I may crash my tiny player...
Wait & see further versions of the editor !
best regards,
Lejigabou
