ROM-Reader for Super Nintendo / Super Famicom Game Cartridges

Hey all,

First off, awesome project! I'm building it for my school project and it's been a ton of fun.

To my problem: I'm trying to flash the PIC but I keep getting a "Cannot open COM port" error when I try to use WxPic. I've tried switching COM ports, to no avail. I guess I'm just not sure how to see what COM Port it's using or how to open the COM. I've done some google searching for COM ports on Windows 10 but that also hasn't been super helpful. Any advice or tips?
