Dreamshell Serial Port SD card problem

[massouji]

I've been trying for weeks to get the Serial Port SD card to play nice with Dreamshell so that I can transfer some savefiles to my VMU. I tried following this guide https://www.youtube.com/watch?v=sAX-_Vzq6mg&t=279s but the SD card is greyed out for me in the Dreamshell VMU Manager. I'm using a GDEMU. I've formatted my SD card to a FAT 32 with 64kb cluster size, and I put the contents of DreamShell 4.0 RC 4 + Boot Loader at the root of my card. Can someone please help me out? Thanks
