R4 card came without cd (as they do now) have downloaded and transferred appropriate software to SD card via R4 website and WinWAR software menu dat files are there but when I put the SD card in the R4 and place in DS it will not boot interface and says cannot find menu dat file.
Where have I gone wrong why is it not working. Some suggest formatting but no one has a step by step guide how this is done the descriptions of formatting to fat files etc are very lite on and assume a level of computer knowledge.

Re: cannot find menu dat file
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.
I just had the exact same problem. The R4 card version I have is the one that uses a micro sd card inserted in it. I had downloaded and installed version 1.18 and kept getting the error message cannot find ds.dat. I formated the card on full format fat32 and then installed a different version 1.14 This has done the trick and everything works fine again.
My nds shown "can't find ds_menu.dat" last night as well because I accidentally deleted it, and luckily that I've just got it fixed. I've tried tons of ways as downloaded the lastest version of the kernel, formatt the sd card, reinstall all the moonshell..., system... files but it still comes up with the same thing once I switched it on. Finally, I format the ds card (make sure you have copies of your games), then download the right version kernel for your nds (because if you download and reinstall wrong version then that "can't find ds_menu.dat" will comes up), so after the download, right click and extract the file, after that, copy the extracted files to your ds card and that is it. It works on me so I hope it also works on you!

Stuck on Loading Screen
This usually indicates that the software kernel on the micro sd memory card has become corrupted. It can also happen if the micro sd memory card is overloaded with games, music and video files etc. The solution is to reinstall the kernel software on the micro sd card and ensure the micro sd memory card is not overloaded. Leave about 25% memory free.
download SDformatter and format the sd card with that, place all the files on there, none in folders..
it sounds like a software problem.
follow the following instructions.
Please can you try and reformat the 2gb micro sd card in your pc and copy firmware from the CD back onto the 2gb micro sd card following the instructions below.be warned that formating will remove even the games from the card so make sure you have a backup of the games saved to your computer. any saved games will also be erased.
To format the 2gb micro sd card 1. Insert sd card into usb stick and into usb port. 2. Close autoplay screen if it appears. 3. Right click on removeable drive. (Eg D, E, F or J etc) that appeared on screen in computer window. 4. Left click on format in menu and when format window appears, tick quick format box and select ok. This will erase all content on the sd card and remove any corrupt firmware.
To reload firmware 1. Insert cd into pc cd/dvd drive. 2. Open cd drive on screen and copy and paste the files and folders from the system/english 1.18 folder on the cd to the removeable drive that the usb and micro sd card are in. The folders that you will copy are "_system_" and "moonshl" and the files will be "menu.dat" and "mshl.nds". 3. Once copied, check removeable drive to ensure files and folders have copied over. 4. Remove usb stick from pc and insert sd card back into R4. R4 menu should appear on DS screen.this normaly sorts this out.paul
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
