Hacking Ez-vi contact issue

[jelmew]

Hello Everyone

I have an EZ-Vi which has some contact issues in my dsi. Because of that, games often freeze and crash because the cartridge looses contact. Now I know of the papertrick, but the external one doesn't work. So I want to apply paper under the contacts. How do I do such a thing with an EZ-Vi Its hardware revision 805 but with the old skin.

Paper tricks are in my Acekard guide. I've no idea if the EZ has teeth, but if it does you'll have to open the cart.

Second question. How do i open the cart. No screws anywhere and it's all thightly sealed.
