Recently got screwed by a used game shop that sold me a non-working copy. Want to obtain one I can actually sit down and play.
I'm not much a fan of NA or how they collect/treat people/horde. It's never been positive. I did a full trace with a multimeter over each trace, polished and cleaned the connectors, replaced the battery, the only thing I can think of is a bad chip
Have you tried the cart in a different SNES? I had a game that would boot 1 in 5 times on one of mine, but worked every time on another. Worth a shot, right?
If he doesn't want to ask there, that's his perogative. If he wants to ask here, that's fine. There are plenty of people (like yourself) who will jump on a WTB thread when they have the item - you never know what you'll find here unless you ask! Try not to be so disparaging of our community - I'm sure you don't know what 21,000 people have in their collections!
I got my Earthbound copy here on Assembler. I made a WTB thread and received a pm. I made the same thread on NA and didn't receive a pm. The guy who sold it to me was great. Good luck DevHackr.
