I've set only two compatible items for my program - http://www.appup.com/applications/applications-Audiobook+Player+for+Netbooks - Windows XP and Windows 7 (yes, I actually tested my software on them!), then someone (from validation team?) added also Moblin to supported operating systems. Is my Windows program really compatible with this Linux-like system? Do you mean that it is runnable via an emulator similar to well-known WINE? Any advice would be appreciated.
