Newbie .... Just got a NDS Lite and confused at all the options for these cards. I dont have any old games from any old consoles - so I have nothing existing I need to keep working. I dont really think Im interested in the Buzzing rumble device, but I do want the latest and most reliable cartridge. So - in a nutshell do I buy the M3 Simply ,, or the M3 Real ... and what are the KEY differences. ( or is there a site which plainly details this ). Thanks in advance!
