R4 update

I do hope Natalie30904 backed up his/her entire SD MICRO content before formatting the card, not just those .NDS and .SAV as you told him/her to. If he/she didn't, hmmm.....

The 'couldn't find SD/TF' issue could be caused by either of these;
1. the _ds_menu.dat belonging to the R4 could be missing or overwritten by accident when he/she added the YSMENU/TTMENU
if this is the case, hopefully he/she'd backed up the SD MICRO content prior to adding the YSMENU/TTMENU cause he/she can simply
replace it again with the original, if not then he/she must search for replacement
2. or a mild case of element contact issue between the SD MICRO and the Flash Cart's; simply re-allign the card in the cart
3. or when he/she added the YSMENU/TTMENU, he/she hadn't format the SD MICRO before adding the backed up files back along with
the YSMENU/TTMENU; simply do over the process, remember to back up files and reformat
4. if the SD MICRO when run in the computer, doesn't get detected, only then it's faulty and need to be replaced
if it's detected and working soundly in the computer, then the case could be either no.1, 2, or 3

 

Let me get this straightened;
You followed koi-fanatic's instruction to delete and format all your SD Micro content. So did you or did you not backed up all the files and folders to your computer before doing the formatting as he instructed? Not just those .NDS and .SAV, but all of the files and folders in the SD Micro, cause I've a bad feeling you didn't since you said "everything is gone". Those files and folders are extremely important for your R4 to run properly, the .NDS and .SAV isn't. Please elaborate on this matter first.

Wondering why Koi-fanatic deleted his post (reply #3), clearly you've read and followed as he instructed. I quoted it, so it'll be there to stay for reference and proof. He clearly told you to delete everything except for the .NDS and .SAV, which is totally going to cost you big time if you did followed it. I'm not going to take over responsibility for other's misleading directions/actions should what I feared be true.

When you said you have an original R4 for the DSL, what exactly is written on the sticker of your cart's body? Sorry to say this, since I'm not sure if you already know or not, since people often assume their R4 is an original version, when it isn't. An original R4 is one that can only use 1GB and 2GB (non-SDHC SD MICRO cards), all else that can run SDHC card higher/above 2GB are not considered as an original R4. If your cart's sticker labelled it as 'R4 Revolution for DS (NDSL/NDS)' only. Without any 'i', 'Gold', 'SDHC', '3DS', 'DSi' stated on the sticker, then yes it's an original R4. Otherwise, it's not. So please elaborate on this too.

 

Good thing you have a copy of those files, or else you'd be weeping.

Anyway, since you've confirmed your cart is an original R4;
Download this WOOD R4 Original: http://www.ziddu.com/download/21056658/WoodR4v1.54.zip.html

Simply download, unzip it, and copy the entire folder into your SD Micro.
Run the WoodR4.nds first before running the gamename.nds
You might need to go to START after running the WOODR4.nds, to change the save file extension from .sav.nds to .sav in order for your
old .sav to be readable.

You can also have this too;
Download this YSMENU R4 Original: http://www.ziddu.com/download/21060584/YSMENUv.6.95r6134.zip.html

Simply download, unzip, and copy the folder into your SD Micro.
The TTMENU.SYS should be put in the same location as your _DS_MENU.DAT.
Again, run the YSMENU.nds first before loading the gamename.nds.

You may have both WOOD R4 and YSMENU R4 in your SD Micro, that's the unique thing about original R4. Those I provide are copies from my own original R4. You'll need to keep up with updates for them to be up to date.

Note:
Remember to keep a back up of the original files in your computer. Or at least do the above method on one R4 first before doing it to the next one.

 

You're welcome. Case close.
