概 要サウンドが出ていない。
詳 細According to the Atari manual, in the sound self test screen, you should hear 4 sounds, with a high and a low for each sound, for a total of 8 sounds. The manual says one pokey is used for the 4 high tones and the other pokey is used for the 4 low tones.

In MAME, you only get 4 tones, all 4 high tones. It appears that MAME is not invoking the second pokey.

I tried this on the current MAME release (.226) for all three Space Duel ROMsets. Happens every time.

On my real game, I made a recording:

I only get 7 tones. In my game, it appears that the first low tone is missing. This could be a case of I have a board problem or it really only does produce 7 tones, even though the manual says 8. Either way, you can clearly hear at least 7 tones, where in MAME you only hear 4
再現手順1) Start up Space Duel (any version)
2) Turn self-text dip switch on.
3) Press 1 & 2 at the same time on your keyboard, when the screen says hit start and select to go into self test
4) Hit 9 on your keyboard to proceed through the self-test screens until you get to the sound self test (a box that reduces in size as it plays each tone)
5) Listen to the missing sounds (hmmm... how do you listen to something that isn't there?).
