This how it was posted earlier :
If you start at the bottom, the part that is inserted in the neo geo when you play.
Both on the left side and the right side are 2 clips you need to try and loosen up.
On the both sides of the cart there are 2 more clips each side you need to unlock.
When you've unlocked all 6 clips, insert gently a screwdriver at the bottom of the cart between the top lit and the plastic thingy that holds both boards, and give it a little push upwards, dont use brutal force here. The top lit will pop up, you need to do this on the left side of the cart and on the right side of the cart, to loosen the glue that holds the cart together on the 2 round thingys, that hold the boards on their place. When succesfull, you can open the cart without cutting or removing the sticker on the top to reach the final clip, that wont need to be unlocked if you follow this way. Hope this makes any sence to you
If you still feel unsure about opening a cart this way i would suggest to let the guy doing the conversion for you open the cart, so the plastic shells dont het damaged.
