Is there any way of using some of the enabled cheats on my flash card online? Ex: Theres a cheat where you can be very thin in mario kart DS, can i do this online? I have an edge card btw (cyclo clone).
If you're referring to the cheats from the GTAtemp cheat database, none of them will work since Narin and others do not approve of cheating online. All cheats that work online are excluded from the database.
If you want cheats that work online you'll have to find them and put them into the cheat file yourself.
