it could be a bad pin connection between the cart slot and the game itself. test the game on another n64 if you have one. Clean the contacts of the cart with a 50/50 mix of 70% alcohol and water and use cutips to clean up the cart and get a good connection.
I'm making an n64p and it's my 1st portable. I have most of what I need on the way from different places...patients is not one of my virtues. Everything but the batteries. Filthy batteries! but I may have a question her or there and instead of making a new topic I decided to make this. Now...
When going about adding the controller elements how do you all go about doing it? Do you make a now board? or just adjust the one inside the contr? Any help with items i'll need and examples would be great help.
