Cheers dude,looks like this is working.Will gove it a go now and let you know the resultsI know you said you're not the most technically apt person, but maybe have a look through this and you might be able to figure it out?

Does anyone know if you can take save files from the DS games (Heart gold for example) and edit them in this save editor?
