Here is a comprehensive article covering what Kemulator 1.0.3 is, its features, and how to use it.
Kemulator only implements the minimal Manager.playTone() from MMAPI (JSR-135). Full sampled audio (WAV/MP3) is silently ignored. A small number of games detect this and fall back to beep-based sound, which Kemulator renders via Beep().
Result: Games like Gameloft's Asphalt 3 run silently, but Snake 2 beeps perfectly.
