I've had this Metal Slug 5 MVS cart for about six months. When I first got the cart, I could play through the game perfectly. Shortly thereafter, vertical graphical corruption would happen after the game had been on for five minutes. Now the same corruption happens immediately after power on.
I checked the Troubleshooting section of the Neo Geo Dev Wiki, and it looks to me like a fix rom problem since the corruption lines don't move with the sprites. But I've checked all 8 Fix Rom pins on the back of the CHAR board, and they're all reading proper continuity with the corresponding leads on the NEO-CMC50 chip. Naturally, I've made sure that both the cart itself and the cart slot are clean. Other MVS games play fine.
Other suggestions on what the problem could be? I'm worried that the NEO-CMC50 chip itself has failed.
