Deleted the "ds_menu.dat" how can i get it back

you can try updating the firmware of your R4(or any brand of DS cart)

if you accidentally deleted the menu for the R4 menu try to reseat the card cartriage if that does not work you need to copy or install the system again

hope this help

did you delete the _system_ folder or the .DAT files on the computer?

you can download the files needed for the r4 just google it. You may need to use dslazy or fixit in order for the game to operate. good luck!

I know you need the new USRCheat.DAT

Put the cheat.dat into you ttmenu.

Hope it helps :D

apparently m3 dont do upgrades now but this might help http://www.m3-forums.net/viewtopic.php?f=4&t=312
basically it converts the r4 ds menu.dat to work on m3 simply (may work for m3 real) so now all you have to do is go to r4 download site and download latest version. 1.18 from here http://www.r4dscart.com/r4-software.html (select the english update) then patch ur dat file replace it back to where you took it from before patching and then copy all 4 files ( _system_ moonshi _ds_menu.dat _ds_mshl.nds) into the root of micro sd card. advise you to copy any files/games you have on your mem card then copy the games over to your newly installed firmware. oh by the way in the link i provided on how2 patch the ds_menu.dat it might be bit vague on where you put the ds_menu.dat file to patch it, all you do is drag and drop it into the PATCH app thats inside the "r4 to m3 patcher" folder. post a reply to let me know how you got on

reformat your micro sd card,"by right clicking the micro card in my computer, you can format it" this wipes the card clean and download the latest software from R4 and then reinstall everything, hopes this helps

The full V1.18kernel can be downloaded from http://r4ds.cn/download/r4_v1.18_kernel.html

HTH

the _DS_MENU.DAT could not be found bcuz you guys probably deleted it or edited it accidentally. if you edited it, put it back to its normal self right away. for example, it was _DS_MENU.DAT.
if you edit it to look like, DS Menu.Dat , your R4 wont work. so fix it to its original self.

Take all the memory contents out to your computer as backup, format your memory to fat32 and put all the memory contents again to the memory from your computer. If not working try downloading the card system files from the card manufacturer site, these files are needed to run the card just like the operative system in your PC, if these files get corrupt or deleted the card wont work.
