the problem is not with the program...(
afaik)...some of them work in some phones/platform/os/models....get my point???
what i meant ism PocketNester Plus, GBulator, etc...might work fine in other phones but may not work in yours...
u need to try out a bunch of them till you get the right one for you (your mobile, i mean)
u may also visit the official sites of these emulators and look at their supported devices/models/os/models/versions......blah blah...
happy hunting!!!
