So you purchased a game or console that some punk kid, who's now an adult, wrote on with a marker and now you have to correct their youngerselfs stupid mistake. The inhumanity!
I cannot take credit for this as I stumbled upon this information on a youtube video long ago. The best and fastest way to remove marker from a cartridge is with a... Magic Erase Marker. Yes, use marker to fight marker. You'll still need some alcohol on hand but simply write over the old marker with the magic erase and give it a wipe with a paper
towel with a little alcohol on it. This simple method has saved me countless times and has effectively worked every time except for once.
