How to open a Gameboy Color cartridge (without having to buy a pesky bit)

Materials Needed:
Lighter
Gameboy Color game (any game will suffice)
Gameboy Color or Advanced SP (not required for the opening of the cartridge, but how else would you play the game?)
One or two plastic mechanical pencils or pens (Two is better in case one is unsuccessful)
Link to buy a bit (if you want to do it the money wasting way): www.amazon.com/...
The lighter used is no longer available (to my knowledge) link to manufacturer: www.prometheusk...
Thanks for watching! I will probably post a video on how to service Gameboy Advance cartridges soon!
