SNES Reproduction Cart

I recently picked up a repro cart of Super Back to the Future 2, and when I tried to play it, the game froze about half way through the first level, and all of my attempts to get it to play after that were unsuccessful. I noticed that when inserting the cart, it was a little difficult to get it in there. The contacts sticking out the bottom of the cart were a little crooked, especially when compared to standard SNES carts.



So I took the cart apart to see what was going on, and I noticed that the main eprom/chip (not a techie) was much larger than standard ones, and it was to the point that the board would not lie flat in the cart. There is a noticable gap when the board lies down which is what causes the contacts to come out crooked when the cart is closed.



My question is, is there another type of cart that I could use to alleviate this? Perhaps a specific cart back that is deeper to allow more space for the large eprom? I bought the game for $15 so it's not a huge deal or anything, but I've wanted to play this game for years. Here are pics of what I'm talking about.

    That thing looks like a harmonica!

    Looks like there corrosion on the legs of the chip.

    You could cut a chunk out of a case like they do with some of the protos I've seen? All the factory SNES shells will be the same depth.

    Looks like a 42 pin to 36 pin DIP adapter. I didn't know CPUWIZ dealt with SNES repros.

    I followed the captain's advice and found a beat up cart back and cut a hole to make room for the eprom. The game worked for a while and I was briefly happy, but eventually it ended up freezing again. It's just a very poorly done repro. Oh, well. Thanks for the help anyway.

    Look over the pins of the EPROM adapter, is there much glossy stuff on them? If yes then that's flux, you can try cleaning some of it away with alcohol and a tooth brush over paper towel. That usually gets rid of random crashes.

    Did Cpuwiz do that or did someone else do it with his parts? That's not a good repro at all.

    I'm honestly not sure where it came from originally, but it is definitely done on a legitimate cpuwiz board from the others I've seen. That doesn't mean they did this repro though. I picked it up at a used game shop, and they almost never have repros or imports of any kind, but recently they must have bought a lot from someone who had plenty. I can tell you that even the label on the cart looked a little cheaply done. The aspect ratio was stretched horizontally on it.
