ha, i just figured it out - in the Disk Control option in the retroarch menu (select+x), if i select Disk Cycle Tray Status it ejects the current disk, then i select Disk Image Append and i can select the .d64 file for the next disk! it appears the .m3u functionality isn't needed (or doesn't work anyway).

@dudleydes That's great information too. Thanks.

I guess I’m the only newbie here.

I use VICE from time to time, but with this I'm just as new as yourself. That said, I don't think you have to type anything in. I believe it's all done through the options menu.
