The problem of the slow loading of the game has been solved. I believe, as some have mentioned, that it was some kind of interference. The solution: While I was poking around in the TE, I noticed the solder joints on the RF shield covering the ICs were sloppy and large. I decided to clean them up and noticed that, at least, 1 joint had overflown to touch a part of the main PCB (one of those small holes/test points). It must have been touching something else (like ground, if the RF shields are grounded) and caused some interference with the system. Since that was the only thing I did while I was in there, I've got to believe that was the problem. Games load fast and fine now...
Thanks for everyone's help!
