I recommend you check http://www.pdsounds.org/ and http://www.freesound.org/ , both of which have sound effects available under free licenses. Be aware that you're still ethically (and usually legally) required to give attribution.
If you want to make your own 8-bit-sounding effects, you can use http://www.drpetter.se/project_sfxr.html .
