How to load/write SD Card in Netplay?

[Temperhoof]

I've tried everything to resolve the ability to save Game Data in Netplay. Since it was disabled in Build 6500, I need to a work around as I cannot use older builds anymore for some unknown reason (computer won't load them). So perhaps someone can help me by informing me how myself and my partners online can load/write SD cards in Netplay so we can play games like Dokapon Kingdom and save while playing online?
