Rom Trouble

I'm having trouble running roms. Whether I try to run them on my DS or my emulator on my PC it always comes up with a white screen. Can anyone help me, Please!!!

Make sure you have the latest firmware for your cart, and justincase you havnt, you need to extract the NDS file from the rar, do this using winrar.

Ok nut that still does not explain why they don't run on my PC. The only ones I found that will run is NO$GBA and DeSmuME and everytime I start it the game begins but then it comes up with the message that you get if you pull the cart out of you DS. The where is says it can't read that data.

have you extracted the roms from the rar file?

^lolthe problem is you need to configure the save type, hit F11 and find the save media type, change it from none to one of the other options till you find one that works. If it doesnt work then it probly wont. DS emulation is still in early stages.
