2.3 gingerbread – Where can I find an Android Froyo emulator for my computer?

I am looking for an Android emulator which supports Gingerbread and Froyo, because I need to test an app and I don’t have any devices that run these firmwares on my hand currently. I scoured the entire internet and couldn’t find any; the lowest version I could find an emulator for was Jelly Bean. I did try to dualboot Froyo on virtualbox, however, it didn’t run quite well and the bigger screen in general ruined the UI.
So anyone know where I can find a froyo emulator for Windows? If it emulates other older versions as well, it’d be a plus.
