Choppy singing games #3

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Singing games like "U-Sing 2" and "We Sing Deutsche Hits" (German PAL) have 
serious sync problems through USB.
However those games works great through DVD and SD card. Hermes cIOS 224[57] 
works great too.

The issue is systematical and easy to reproduce.
From my tests with U-Sing 2 the lag appears:
 - with rev19, rev20, rev21 and all d2x (can't test lower revs since base 57 is required)
 - through USB only
 - with any USB device
 - even if the watchdog is didabled

I suspect the lag appears in U-Sing 2 because the HDD is continuously accessed 
while singing (the led never stops blinking).

Pretty sure it's a EHCI module issue.
In fact with the new experimental EHCI module the lag has almost disapperared, 
but unfortunately that module is not stable yet.

Someone at usbloader googlecode has also pointed out that D2X only detects the 
usb microphone inputs at the load/start of the game, whereas the normal 
operation of the disc game, or if using hermes with usbloader, should detect 
the mic input even when plugged in during the running of the game.

Yeah I know already.
The new experimental EHCI module can detect mics in game but as I said it's not 
stable yet due to random crash.
I really tried to fix it but no luck. :(
I think I'll release it as a svn branch in the hope that someone can contribute 
with a fix.

Sounds great. My birthday is coming, maybe the best present is yours. ;)
I only understand a few of hardware programming, so I can't follow your 
technical explanation, but it doesn't matter. YOU are doing a great job for us, 
the results are excellent! I really love your way of transparent information.
