Usually when there are problems with booting roms on the r4 it is because the kernel is out of date. Download the latest kernel for your r4 at http://www.r4ds.com/download-en.htm
If the games still don't work, you might need to replace the arm7.bin file in the game. To do this, you will need to use a program called DSLazy. You can download it here. So to replace the arm7.bin, you will need a nds rom that works without the arm7.bin fix.
Step One: Start DSLazy.
Step Two: Browse for the file that works without the fix (I use Tetris DS)
Step Three: Click Unpack. This will create a new folder called NDS_UNPACK
Step Four: Move the arm7.bin inside the new folder somewhere safe. Close DSLazy
Step Five: Complete steps 1-3 again.
Step Six: Now open NDS_UNPACK that you just created with the game you want to fix and put the arm7.bin that you moved from step four into the NDS_UNPACK to replace the one already in there with the new one.
Step Seven: Click NDS Packer in DSLazy. This will create a new version of the game you want to fix with a new arm7.bin
Step Eight: You are done. Copy the game to your r4 and load it. The game should work.

If this didn't work, which shouldn't happen, try re-downloading your roms.
If it STILL doesn't work, there might be a problem with your r4, and you might want to get it fixed or get a new one.

~hope this helps.

R4 Problem loading error

Get this file extract the file with winrar, and copy the files to the DS card. The file structure should have is:
Files
  • _DS_MENU.DAT
  • _DS_MSHL.NDS
Folders
  • _system_
  • moonshl
You should now put your .nds files onto the root of the card also, and hopefully all should work OK for you

R4Ds not working on NDS I

oh sorry didnt read your post right the first time, you have a new dsi? nintendo have been clever in not only makin the dsi region bound unlike the normal ds lite, meaning it will not play games from other regions where as the ds lite can but it does also made sure that the new dsi does not support any super card, be it the r4, dstt, n5. they are gits. the r4 ,dstt teams etc have promised to do cards that the dsi supports but dunno wen avalible yet and im guessin will cost more, sorry to let you in on this gimmick that nintendo have caused.hope this helps.

Nintendo DS Lite not reading some games

this is a problem with the pins inside could be dirty or dusty ether way you will need to get a cleaning fluid ie 100% alcohol cleaning fluid us a clean cotton bud inside the slot and use gently as not to damage pins, if the pins are heavy soiled you may need to get a fiberglass tipped pen wich is used to clean up poor contact areas on boards and other electrical circuits

hope this helps if unsure get in touch with nintendo they will prob fix it for you for free go here > http://www.nintendo.com/consumer/repair/

Cant use ROM's in my NDS and R4

Hi Patrik,

I have had this problem with several R4 cards that i have mended for friends. Basicly what is happening is a file known as an ARM7 file is not being read properly.

There are a few ways around this problem.
  • You can download a NDS patcher/unpacker and unpack/repack the game that is giving you problems and replace the ARM7 file with one from a working game. (the unpacker will generally come with a working ARM7 file) i use one from GTA chinatown wars.

  • You can go to the torrent site and look for the game you are havong problems with and 9/10 you will find one saying 'R4 fix'

This is a link to a decent site that helps if you wanted to try it for yourself. http://cupevampe.blogspot.com/2007/12/how-to-patch-nintendo-ds-rom-tutorial.html

Good luck

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.
