Summary 04244: starwars and clones: Tie fighter 'roar' sound broken
Description When the TIE fighters swoop past in Star Wars I no longer hear their usual sound but an 'broken' type of sound.
Steps To Reproduce Just play the game - when the Tie fighters appear and fly past you'll hear an ugly noise instead of their usual sound.
Additional Information Lord Nightmare instructed me to raise this as an official issue: "However, can you file a bug report for it on mametesters? It should be assigned to me, if you can do that."

 <LordNUniv> current blocker on the star wars speech/tie fighter bug in mame is me not being able to get PES running in mess
<LordNUniv> PES is a test bed machine using an 8031 to play with a tms5220 or 5220c
<LordNUniv> which i use for data logging with a logic analyzer
<LordNUniv> however i need it to run in both emulation and real life to compare traces
<LordNUniv> and emulation is being problematic; I can't get the 8051 serial ports working
<LordNUniv> i must be doing something wrong

 Any progress on this bug? I don't wish to pester but it's a year since I reported it so I wondered if you were any closer to a solution?

 pri88 yes it's still broken, no need to reconfirm that.

cyberfrem I understand, but please don't ask for progress reports on this database.

 Compared to the original pcb, this issue seems to be solved.

Original hardware video here. In minute 6:00 the tie fighter sound can be heard several times, and it sounds the same as in current MAME.




More original hardware here. Perfect tie-fighter sound in 6:38, 6:43...



This is how current mame is doing that sound:

 After Metalgod's posts, I'm going to call this a BTANB and say that MAME is currently correct to hardware, but unless we can match the tms5220 bit-for-bit in emulation compared to running the data through a real tms5220 with a logic analyzer tied to the debug-digital output pin, I can't claim that it is 100% accurate. So just leaving the possibility of re-opening this in the future. Marking as resolved for now.

 It is likely, if it was fixed at all, that this was truly fixed in the commit 12d07f91741615bb811e122ffc15ce8cf39f6266 since there were some random speech glitches in various games before that commit.
