R4 SDHC - Save file corrupt and gets deleted on restart HELP PLZ

HelloMy R4 SDHC (with a 4gb Sandisk Mirco SDHC card) runs most DS games fine however with the exception of Might and Magic Clash of Heroes and Knights in the Nightmare.Yes they load up. Yes the game works(i.e I can play) and yes the game "saves".But this save file somehow gets "corrupted" and "deleted" on restart. I have checked the card and the save file(.SAV) is surprisingly still present when I load up my card on the computer.I have tried formatting the card and using the latest firmware (1.29) at point of writing) to no effect. I have even used the ARM7 fix - which turns it into a new problem in which the save file is not even recognised.
Please help.
Theres no way I am going to play a game for 25hrs straight or keep the DS on.

i don't know what the problem is and a r4 is not a good card right
and maybe you need to back-up your files
and send some pictures whats happening maybe we can help?

anyone else have this problem??

possible u have a fake R4!

Might & Magic: Clash of Heroes is Anti-Piracy protected, maybe there's the Problem.

RiceMuncher · #3anyone else have this problem??

Someone else had this proplem with the same make of cardhttps://www.romulation.org/forum/index.php?topic=30641.msg532503#msg532503Im not starting to this they mabe a problem with this brand...

Yes I have had the same problem. The above message is my thread. -_-still no soluton

I have this problem with an R4 SDHC bought from a recommended website.Haven't tried it with this game, but with New Super Mario Bros. and with Phoenix Wright Ace Attorney I have issues with the save file.With Phoenix Wright it says "Load Failed" when I try to continue my game. Exactly the same after I patch it.With NSMB is gets past the "Nintendo" screen and then says "Save file corrupt, deleting saved file" and then repeats. After I patched it with Arm7 it said "Save file corrupt: File 1, File 2, File 3" and then proceded to delete those files and then took me to a black screen...Anyone have any idea on this? If the R4 SDHC is the problem, then which card should I be getting, as this was the one I thought was highly recommended...

Thanks for the replies.I was looking up this problem and it seems to be fairly prevalent across R4 cards.
I recently tried converting the 512kb .sav to 1mb. Which does not work... BUT if i run DSPATCH.nds (will attach file) itll run the game and load up the 1mb file..only thing is, it still cant save properly...
I think this is a firmware problem =[ ...BTW. www.r4sdhc.com is the site for my R4. I brought it from gadgetgear.com.au

Summary of following suggested solutions1. Format SD Card
Result: Does not have any effect.
Note: Unable to format to FAT16 because of cluster size issues2. update to latest firmware
Result: No effect
Note: 1.29 is the latest as of 26/12/093.ARM-7 fix
Result - Save file cannot be accessed instead of save file is corrupted.
Note: Only tried one donor rom - Glory Days 2(U).ndsIf anyone has similar problems with a R4SDHC plz try out those solutions and post back on results =]
Ill add more in as I try and fix this ugly R4 problem

Hey RiceMuncherI'm having the same problems and have tried the steps you've suggested. I've downloaded about 15 Roms and have been through them all to see which ones are having problems.The majority have problems retrieving saved data, a few can't load at some point. (I've only tried your steps with 2 games)For what it's worth I'm close to giving up on the R4 SDHC because many posters on this website seem to say the R4 is a bad card and go on to recommend the AceKard.As I understand it that has a very high compatability (no games shown to have problems) and saves with everything. (Unless I've misread something).
Another cool thing about one of the AceKards (The RPG) is that you can leave it in your DS and through a USB port put Roms straight onto it:D

THERE IS A SOLUTION!!!!

This thread follow the guide complelety,
when u get to the opition of what numbe 1,2,3,4 go for 4.
Now then make sure to download the firmware from the website as well and put everything on ur R4 chip.
Then when u first load ur ds (will take a lil bit but not long) go straight for the ysmenu.nds then it will save the data (by pressinga)
then play ur game thru this.
:D IT WORKS SAVES AND DOESNT CORRUPT

Ok will try

(qouted from afrokid13) (https://www.romulation.org/forum/index.php?topic=28719.0)you guys didn't use the latest YSmenu. Read carefully the instructions are up thereLatest YSmenu firmware http://home.usay.jp/pc/etc/nds/
to find the file press f3 then paste this into the search bar 2009/03/27 00:00download that fileand RENAME it to this "YSMenu0810211800" (without the quotes of course)thats not the file you are supposed to downloadthis should solve supernova and Noob1996's problemPost Merge: [time]1261888109[/time]
OMG!
IT WORKS!!!
Installing YSMENU solves it.
Thanks ZAN.Someone make this a sticky plzzz. Everyone with a R4 or R4 clone should know about this

Well I've followed all of the instructions. I'm running YSMenu on my R4SDHC - when I load a game it takes a damn long time to get past the "Booting... Creating TTMENU.sys" screen for the first time but Ace Attorney is working!Got bored of waiting for NSMB to load up.Thanks guys!This thread or at least the problem should really be put into the common problems thread.Will see how it goes with the rest of my games and report back if there are any that don't work.I presume you got Might and Magic working then RiceMuncher? Working fine?

No problem. it has taken me far too long to solve this issue.
Also it does take ages to booting... but its worth it. Well I did this for professor layton and it works well.

yep my previous two games that wernt saving properly - Knights in the Nightmare and Might and Magic now work fine! xD
good work to Zan.This shows one thing - R4 fireware SUCKS esp R4 clone fireware.With regards to your TTMENU.sys loading time, it shouldn't happen ( it happened once for me and froze my DS) . I re installed using the R4.bat and cahnged a few options and it works great. Maybe try reinstalling?
