- Several tracks from Perfect Dark and Super Mario 64 don't work with full delays.
Alien Conflict, for one. Slider from Mario 64 is another.
Shadow Man is broken no matter what I do, causing a total lockup, which is why I originally had the no-Audio Interrupt timeout, but I somehow can't make that event work in a universal way, as it either doesn't work, or times out too soon on some rips that have an extended boot up sequence.

- This seems to be the result of missing code in the RAM, which leads the code to start executing NOPs and whatever is after that.
At least for Perfect Dark.
To test this I re-ripped it and it plays fine.
Same story with Shadow Man
I first tested this with Turok 3, because IIRC it was the most problematic as it did lots of weird stuff with Audio Interrupts and timing, FP Registers and TLB mappings.
This too I re-ripped and it works fine.
Probally even better now, due to the batch-ripper being better as well as myself ripping it :)
Interesting stuff.

- @ Josh W Thanks or the PD re-rip! I played a few tracks with HLE off and they seem to play and loop without crashing compared with before. I noticed there was a little delay between songs playing but worth it if the music plays flawlessly :-)
All is good and hope for smooth sailing :D

- Sounds to me like a lot of things may need to be re-ripped. Just makes me wonder if Mario Kart 64 could benefit from a rerip, or will it still be at the same speed.

- Well, in order for "correct" emulation it's necessary for most of them to be ripped because of the missing data.
I say "correct", because it may actually not make much difference.
Because, generally any set works fine now, reripping will most likely not make any difference.
It's just the onces that don't run.
Now, looking at Mario Kart 64 in particular, when I record it into Audacity, there seems to be no difference between full delays on or off.
It doesn't run with _enableFIFOfull, so I may give that a rerip and see if that flag makes any effect.
Though, comparing it against a Youtube recording it is definately slower, and the waveform seems to be inverted. Not sure what is going on there.
Might do a recording myself and see what's going on

- Can confirm it's inverted, proof
Though this shouldn't have any effect on what it sounds like.
Though the screenshot does show everything starting out the same speed, then the recorded version speeds up

- Hey, i do hate to bother you, but would a USF rip of all of the music from Lego Racer's be possible?
- by Josh W at 12:40 AM EST on November 6, 2017
- And the Final verdict
I reripped a track of it that I was using above, with enableFIFOfull set and the timing was pretty much spot on.
Though the full delays didn't affect it at all.

- I guess that answers that.
On something else, I decided to check if a Mario Party track was ever fixed. A long time ago, I noticed the "64 Board Outro" was playing the wrong track, it was playing the Turtle Village theme instead. The problem I found was it was looking at the "NUS-CLBE-USA-2" usflib for the data instead of "NUS-CLBE-USA-1". I submitted a fix somewhere here a long time ago, but it never got added, so currently one of the tracks is a duplicate causing one song to be missing.

- And now a full re-rip of Mario Kart 64
And by popular demand, Lego Racers
