SERIOUS ISSUE - Extending Cart Connector

[XCVG]

Likely it is the game. There might be a dirty contact, corrosion, or SOMETHING that causes it to output a marginal signal that's good enough on an unmodified system but fails on a relocated slot.

As has already been said, the problem is definitely the length of your wires. You can't use much more than 3~4", even with awesome wires, and expect it to work with all games. Especially SNES games such as Yoshi's Island with add-on chips.

Shorten those wires! Either re-design your case, or expect glitches.

I did. :/ They're around 3.5" now. Other than SMW2 though it seems to work perfectly fine, and I'm at the point where I can't really do much about the case design, so I'm calling this one done. I've accepted it for what it is. It's something I'm keeping in mind for the future though. NO MORE than 3" when extending if at all possible.

Yeah, it makes sense. The SuperFX chip required pretty close timing to work correctly. Yoshi's Island uses the 20mhz version as well, making it even pickier that Starfox..

It might also be worth while to try some different solder. Some of the newer environmentally solders can't match the electrical properties of the older stuff.

I don't know if it would help but you can also put parallel runs of the smaller IDE cable. It will do the same thing as using bigger wire but is probably easier to route.

You just have to be sure the parallel wires of the same contacts are the (exact or so) same length as each other, path of least resistance.

If you use 80 conductor cable, then find the data bus and put a ground wire between each and every signal. You have the extra wires. Thats the only difference between a 40 and an 80 wire IDE cable - every other pin is ground because it blocks electromagnetic radiation and allows for an acceptable error rate at higher speeds.
