1. Copy some or all of the above files to the iTouchDS_All_In_One folder and double click on 1.All_In_One.bat to patch the files, then copy all of the files back to your iTouch folder
Note: If English language interface is the only one you use, you only need to patch the files that ends with .eng, and ignore all the errors.

2. Copy global.nds from the iTouch\gobal folder to the iTouchDS_All_In_One folder and double click on 2.Global_nds.bat to patch the file so that all languages are selectable, then copy the file back to the iTouch\gobal folder.
Note: Keep the patched global.nds then you don't have to patch it again when a new firmware comes out

3. Copy boot.gb to the iTouchDS_All_In_One folder and double click on 3.iTouchBoot_gb2M3Real_g6dsload_TPload_eng.bat to create a g6dsload.eng file then copy the file to the System folder in this package. 
Note1: for ITouch to be the only firmware on your M3Real, copy the System and iTouch folder to your MicroSD
Note2: for iTouch as an extra firmware (boot via Sakura 1.1x, see 4.), don't copy the System folder to your MicroSD
Note3. for iTouch to boot in Kaura's Main Menu Touchpod icon, rename g6dsload.eng to TPload.eng and copy it to the System folder

Optional:
4. Copy boot.gb to the iTouchDS_All_In_One folder and double click on 4.Defaulty_nds.bat to create a Defaulty.nds file, copy this file to the root of your microsd (use for booting to iTouchDS via Sakura 1.1x)
