Have investigated those issues for few days now (Win7/64, Intel SU4100):
a) Bluestack, does not really run on my machine (frequently crashes), maybe causes by graphics adapter incompatibility (according to forum)
b) VirtualBox (v4.1.18), buildroid_vbox86t_4.0.3_r1-20120518_gapps - Locus works quite well
--> only issue: no access to local data outside VM (LAN works fine), TotalCommander installed on VM-Android
b1) USB - although connected to USB device via VirtualBox there is nothing at /mnt/usb/...
b2) no access to local drives, although set via VirtualBox Shared Folders
b3) only solution is installing LAN PlugIn in TotalCommander and connecting to local WinServer - then via that link copying data (e.g., maps) into Locus is feasible.
Any ideas to get b1) and b2) working (to skip b3)?
Thanks and regards, fussfolk.
