Sega Genesis Cart switching ideas and questions.

I've been pondering over a big problem with a project I have. I need a way to do game cart switching on a Sege Genesis for my project "Fusion Rising. (YES, it is still in the works. just been too busy with life to give it time.) I did some research for this and found out that most devices that do this usually switch between the !C_OE, !C_CE, and VCC pins to select witch game slot is loaded. Perhaps the GND pins are switched as well. I also found that many don't know if this will work through a 32X or not. I need to know since my switch would be after the 32X and not between it and the console. Any ideas? I'm willing to experiment on this if I can get a 32X that works for more than 45 seconds.
