Changes

Hello, I do think that many of these are currently used by completely no-one and are just wasting space, for example vba-rr(vba-m and bizhawk cover the uses), DMGboy and nintemulator.

Others, like VBA, no$gb, TGB Dual, VGB and gearboy are mostly undeveloped, or inferior to other options. It would be beneficial to add used emulators that offer new features, as those are important to have judged, for example GBE+ of HhugBoy.
