Hi by acident i deleted ds menu.dat for my r4 card revoloution and when i turn it on it says couldnt find menu .dat and i dont know what kernal download to do or anything please could you help.

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

This is an error from an R4 Card. You need to reinstall the firmware for your r4 onto your micro sd card. The firmware can be downloaded for free on the manufacturers site usually written on the front of the cardand on the box . As i dont know which version of the r4 you have i cant give you a link for the exact firmware to use.

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

plug your usb for r4 in (with the adaptor) . go to "My Computer" , select "Removable Desk (F:)" .

when you do, look for _DS_MENU.DAT, if you cant find it, thats the reason for your R4 not working. if you found it, but your r4 is still not working, you've lost some systems for the R4, such as DS MSHL etc.

if you have, i advise you buy a new adaptor.

To format any drive just insert the memory, right click over your memory drive in My PC window, and there should be an option to Format this drive, formatting will erase all the card contents so make a backup in your computer first.

When you click on "format" a window will appear to chose FAT or FAT32 (try FAT32 first then if not working try FAT), dont have to do nothing on the size option, write a label for the drive if you want, not needed, let Quick Format clear, click on start button and you'll see a proccess bar, when it finish it tell you and you have a formatted drive.

Put the sistem files and one rom to test again in the memory, test it on your DS. Be sure you have the right files for your card, the www.R4ds.cn site only supports R4 cards, not R4 III, R4 SDHC or any fake non R4 hardware.

GO ONTO R4 WEB SITE DOWNLOAD LATEST FIRMWARE PUT ON TO SD CARD,THERE IS SYSTEM,MOONSHL,DS MENU DAT,DS MSHL NDS THEN IT SHOULD BE OK.

HI REFORMAT THE CARD FAT 32,DOWNLOAD LATEST FIRMWARE ON R4 SITE WHICH IS 1.18 VERSION, THEN PUT ON CARD SYSTEM, MOONSHL,DS MENU DAT,DS MSHL NDS,IT THEN SHOULD BE OK,UNLESS YOU HAVE THE NEW R4 CARD WHICH SUPPORTS SDHC,THEN YOU WANT VERSION 1.19.

hi

first of all , check your r4 version.
there are many.

have you put the right firmware on your r4?
original : http://r4ds.cn/download/r4_v1.18_kernel.html

r4 revolution pro : http://www.r4dspro.com/download_en.html
r4 ultra and de luxe : http://www.r4deluxe.com/en/down.asp
r4 III : http://www.r4dsl.net/download-en.asp

after that it should work.
or maybe you should format your memory card first.
