I have a nintendo DS Lite, i was wondering if i need software for the ezflash V to work, or can i just put the gba file on my r4 and it automatically works? Anyone know? Also when i download rar files, i unzip these random files with the nds. Are those just the author's/uploaders name? or what does it do?
Not sure about the EZflash 3in1 SLOT2 question. I don't have an R4. And yes, those other files are usually just an nfo (Contains data about the game, though I dont know how to view them) All you really need from the folder is the .nds file.
you need GBA Exploader for it to work. extract the files and just drag them onto your r4.then run it and play. http://www.filetrip.net/f3680-GBA-ExpLoader-0-58b.html
Depending on your firmware, you may have to use a Homebrew loader like GBAExploader. You run the homebrew, and use it to load the GBA games to your EZFlash 3 in 1 and play them.
