I've had this error for a while now (not just with version 19). When I try to copy back a Game Boy save (tried Pokemon Gold today), it says there's not enough space and I need to free up 32kb of room (the size of the save in this case). I've unchecked the read-only and archive options on the save file and it still does it. I tried editing the save with a hex editor and the change didn't stay. Any ideas?
Which hex editor? Did you make sure to save the file in place (disable backup option where editor renames old file and creates a new one?)
Also, http://www.retrode.org/documentation/troubleshooting/troubleshooting-saving-files-to-the-retrode-does-not-work/ (http://www.retrode.org/documentation/troubleshooting/troubleshooting-saving-files-to-the-retrode-does-not-work/)
HxD. I'll try it again and see if it works.

... I've unchecked the read-only and archive options on the save file ...
The Retrode does not care about the file's read-only attribute, only sets it to tell the host (PC, ...) that writing to the file is pointless. :)
To make the save really writable, you must set "[sramReadonly] 0" in RETRODE.CFG.
Sorry for the delay. I tried it again today (just overwriting, no hex) with a different game, Zelda Oracle of Seasons, and it gave the same error. The save size is only 8kb. SramReadOnly is set to 0.
The save data can only be changed by overwriting the Retrode's save file in place. However, some copy commands, when asked to overwrite file X, instead create a new file Y, then delete X, and finally rename Y to X. The Retrode does not support this or similar procedures, as they would require a lot of buffer memory.
The same restriction applies to the Retrode's config file.
I expect the following method of overwriting a file on the Retrode to be reliable:
- "Delete" that file on the Retrode. I repeat: on the Retrode. Note that it must be a permanent deletion command. Moving the file to the "recycle bin" will not work.
- Copy your file to the Retrode. Since the only free space is that of the deleted file, the data should go exactly where it is supposed to.
Warnings:
- The name of the new file does not matter to the Retrode. If you delete the save file, any new file will overwrite the save data.
- Do not delete more than one Retrode file at once.
- Do not edit another Retrode file while one is deleted.
Other notes:
- After connecting the Retrode, please verify that the read-only attribute of the Retrode's save file is already unchecked. This is to confirm that sramReadonly 0 has really taken effect. If it didn't, try editing the config file as described above.
- If you look at a file after editing it, the host usually shows you cached data. You must safely remove / unmount and reset the Retrode to see if the written data was really stored.
- When using HxD to edit a file on the Retrode, make sure the option to create backup (BAK) files is unchecked.
Thanks! I'll try your suggestions the next time I need to copy a save.
