Summary	00695: narc, narc3: Problem with Sound Test Mode.
Description	When in test mode, if you perform the synthesizer sound board test it reports 3 tones-ROM error U5 (occasionally I'll get 0 tones-no response check U5), upon completing the test, the sound board crashes, and all background sound is gone. But if you leave it alone and don't test the board, synth sound works fine in test mode and in game. Update: Now when performing the Synth Board self test, it no longer crashes the sound. The Synth board still isn't responding to communication. But instead of returning '3 Tones - ROM Error check U5' it returns '1 Tone - Synthesizer OK/Check J2 Cable'. So its improved some. Here's test results of the other games in this driver: The following Y-unit games report... [ERROR - Sound IRQ Not Detected] and [0 tones Check hardware] trog mkla1 term2 these next few report [0 tones Check hardware] hiimpact shimpact the following reports [No Sound board IRQ Line Detected] totcarn and the following don't report anything because they can't test for it: strkforc smashtv
