ms0 and flash0 custom folders

[gid15]

since i upgraded to win7 64 bit, i've been keeping both 32 and 64 bit versions of jpcsp since both have their good/bad points.

i'd like both to use the same ms0 and flash0 folders, so that i wouldn't have to keep 2 copies of the same thing and constantly synchronize stuff, and also to prevent accidentaly overwriting flash0 with the stuff from the zip.

is it possible to add that?

I'm working on a new virtual file system (VFS) where it will be easier, for example, to map directories to PSP virtual devices. I will add configuration options for the VFS so that mapping of one or multiple directories (like for the umd directory) will be possible.
