I am really interested in your project and would really like to help out but I am in no finacial postion to buy anything at the moment. I really think this pcb would be great for portables and the like. Was wondering tho, if it were possible to get one to test some things on? I have 2 NES boards one has the older ram on it and the other has slimmer ram on it. So maybe I could test to see if that ram actually works with your issue with the actual game cart not working.
