I may have been collecting MVS games for years, but it's only been recently that I've run into carts with issues that aren't simply resolved by cleaning the contacts. That being said, consider me a n00b at MVS repair.
I recently picked up a Magical Drop 2 cart. The boards are legit (seen below), but it has a bad sound issue that will be readily obvious watching the video I've embedded below.
When I look at the boards, most everything looks fine. There may be a bit of solder that could stand be reflowed, and there's some gunk on the contacts that I can't seem to remove with the usual alcohol cleaning method (pic 3 below, left side - a little hard to see due to the flash). Other than that, though, nothing looks too bad. Not any worse than any other cart I've ever had, anyway.
Any ideas if reflowing will help or tips on removing the gunk without damaging the contacts? Or maybe just which section of the board(s) to focus on? I know there's a site out there that outlines the parts of each board, but I can't seem to find the link right now.
