In another thread there was a discussion about making quick backups of sav files and the outcome was that this is supported with 4 save slots. I tried it but it results in a hangup of Wood R4.
The problem is that this is not a hard error. I tried the following:
- Format with Panasonic SD formatter
- Put the __rpg folder on the SD
- Put the _DS_MENU.DAT on the SD
- Put Another Code - Two Memories.nds on the SD
Then start the SD, start the ROM, reset the DS. Go to the ROM, press Y for File information, Y again for Settings, Y again for Copy Slot and OK to save the default slot to slot 1 and press OK to confirm copying.
Now this actually works. But it failed on a more loaded SD card. So I repeated it, see picture below for the actual files:
- Format with Panasonic SD formatter
- Put the __rpg folder on the SD
- Put the _DS_MENU.DAT on the SD
- Put all the other folders on the disk
- Put all the homebrew NDS and SAV files and miscellaneous files on the SD
- Put Another Code - Two Memories.nds on the SD
Then start the SD, start the ROM, reset the DS. Go to the ROM, press Y for File information, Y again for Settings, Y again for Copy Slot and OK to save the default slot to slot 1 and press OK to confirm copying.
Now the Wood R4 hangs hard. This is how the SD card looks like (sorry for the localized names):
After the restart it turns out the save file for slot 1 is not created. I repeated the process with another SD (this was 1 GB Transcend, also tried a 2 GB SanDisk) with the same result, hangup and no file created.
I tried to reproduce with less files but that didn't work because than it works. However I saw some strange GUI artefacts like the pulsing icon shining through the dialogue.
You do not need homebrew to reproduce, if you will load it with other files it can show the same result. As said, its not a hard error so there is also a chance it works. Then try another combination of files.
The R4DS used is a R4DS v2 from 2007, bought just after the plastic shell was changed and spring loading of the SD was replaced.
EDIT: this is fishy. The very same SD that had a hangup yesterday now works. Same procedure, same files, different results. I guess it will be hard to track this one down with no stable way to reproduce the problem. Also my 2 GB now works. The only thing that is different is the time of day and date and that I charged the DS over night. By the way, I never had a problem with copy/pasting files so file access in general works okay.
