Rad Racer won't work?

whats up with Rad Racer when I try to play it on NesterJ? Theres no sound, I tried setting the
control configurations but it keeps changing screen sizes. Anyone know how to get this working?

Holy crap you mean that old game on the NES? Before I go on with guessing, is the emulator itself (the exact version you have) support sound in the first place? I really didn't understand your question about the sound and the control config and whatever xD

it works now, I just realized I haven't had the latest version NesterJ.
