Summary | 08876: specpls2 and clones, cpc464 and clones, others with a monaural cassette device: Stereo recordings of tapes get their Right channel discarded | ||||
Description |
Currently when loading real recordings of Stereo cassettes, MAME will only use the first track (Left channel) instead of mixing both. Some games for systems with Monaural tape decks were recorded only on one of the Left/Right channels and, since the Right channel is always discarded, the latter will refuse to load in MAME when playing back accurate recordings of them. |
||||
Steps To Reproduce |
- Load specpls2 driver. - Load the attached test program that's only recorded on the Right channel (File manager - > Cassette). - Press enter to start the Tape Loader. - F2 to start tape. - It will fail to load. |
||||
Additional Information | Exceptions to this would be any systems which did read two separate tracks, such as the Atari 8 bit computers and the Sega AI. | ||||

From what I recall, the reason for this is one channel would lag behind the other, creating an echo effect, and cause loading to almost always fail. Acknowledged for now. |

But mixing both channels shouldn't have anything lag behind if they play in unison... And sometimes it does make loading succeed when it fails otherwise. |

a stereo tape being read / played back as mono should not cause an echo, that's a MAME problem. |

Maybe the problem is that Stereo tape players actually split Monaural tracks in two in an anynchronous manner, in which case perhaps the user could just have a "Play channel: Mixed/Left/Right" selector in the Tape Control menu, when detecting a Stereo recording on an emulated Monaural deck? |
