Hacking Transferring DeSmuME save file to an NDSL

[xuerebx]

I was playing Pokemon Diamond on a 0.9.7 DeSmuME emulator when I decided to buy an NDSL. Few days later and I got an NDSL with an R4i3D flashcart with games (not a good flashcart, but that's the one I found locally and cheap).

So, I was wondering if I could transfer the save file on my emulator to my flashcart? Do I have to just drag the battery file to the micro SD card? The extension is .dsv on DeSmuME, I believe I'll have to change the extension to a .sav or something like that. I'm not too sure.

Thank you.

Yeah, it's the battery save and you might be able to just drag and drop with no conversion (extension changed of course).

If you do need to convert (I don't know what format that cart uses), you can try an online save converter.

The "raw format" is the kind most flash carts use.

Thanks, that link looks useful. Is there a way I can check with my current files to make sure I get the correct file format and size when I convert the battery file? I've got a couple of games (some Pokemon games too) which I am already playing so I can compare with those. The file extension I can easily find out, but the size as indicated in the link you gave me I'm not sure how I can determine it.

I wouldn't use pokemon games for testing, some of them change the save size depending on how many PC boxes are in use.

Auto-detect should work just fine there, it's likely just used for either padding or trimming when somebody knows they need the size altered.

I see. Thanks for your help, I'll update this thread in a couple of days if I run into problems. Hopefully not.

Well, just to update this thread and say that changing the file name from .dsv to .sav worked on my nintendo ds lite. Thank you.

For starters, that Save Converter is awesome.

Anyway, I'm trying to convert my Retail Cart saves to DeSmuME format. Is a retail cart save considered RAW? And, will that work with Pokemon games?

 

[Rydian]

Retail games are RAW last I checked, and yeah the converter works with pokemon games.

Another method which is kinda foolproof (going by my experience) is to go via

File >> Export Backup Memory.. >> *enter name here. Just rmbr to make it the same as you ROM's. But you can edit if later if you made a mistake* >> *keep it as Raw Save Format (.sav)* >> Ta- da. All good to go.

Thanks guys, that converter works great. I dumped some saves with a NDS Adapter Plus from a retail cart. I converted them (RAW Format) to deSmuME format. Then I added them to the battery folder for my deSmuMe and named it the same name as the rom (minus the file extension). It loaded up in the emulator like a charm.
