u need an emulator
It's not possible n00b.
Standard .nds game files are 128MB.
You can't download save files. <--- This dude fails. you can download .sav files for nds games that is presuming you have an R4 or similar. just type in the name of the game you want a sav file for and add .sav to thend in google, it may take a bit of looking but you will find one eventualy.
First you have to download winrar.Then you download whatever ds game you are downloading .Then you right click the ds game icon.Then you click extract all .Then it has been converted into a nds file.
You just have to add a folder named "Games" on the root folder then download .nds files which are the ds games. You put the nds files in your "Games" folder. A very popular nds ROM site: romulation.net To play the game on your R4, you just have to navigate to the "Games" folder and click your nds file, also when playing your first time, it will ask you to create a SAV file (a file that saves your process, stores data, don't worry, it is only 512 kb). Have fun!
Use sendbig .com to send any type of files for free up to 30GB
yes there is a way to fix it easy i discovered it ok to fix all the saves you need to add on the end of the NDS file .nds and for the save file .nds.nds and the saves will work
no not unless u hack the files that run the r4 firmware (which would be v hard)
The games are ROM files, the emulator is the virtual game system. If you have the NDS emulator, you need to acquire the ROM files you want to play as well... Normally, there is an option to open a file in the emulators menu. Select the ROM file you wish to play from the file browser and you should be able to play
