MAMEWorld Forums - EmuChat - Re: Mario Walking...0.141u2

couriersud & Derrick Renaud,

Thank you very much for your replies. I truly appreciate it. I guess the only last thing I may 'bank' on is something else is discovered down the road which as a 'side-effect' will cause the other sounds to be louder or the walking sound to be lower/softer.

Something similar I believe transpired with Phoenix***, that long after after all the values were measured and tested from an actual board; something else was uncovered as a final tweak which did fix some still so-called 'outstanding' issue(s)...

...Or maybe not in this case. Either way, the love you and dedication you both show to this project is admirable. I'm grateful you're both on-board with this project, and also the consideration and time out you have taken to explain and reason with me. Thanks, again.

***After a check over the drivers history at MAWS, I believe what I am recalling is after these fixes:

0.104: Derrick Renaud changed R22 to 470 ohm per real board of the Phoenix discrete sounds. This should fix the remaining complaints with the discrete sound. The shot & explosion noise sounds still need discrete emulation.

0.103u5: Derrick Renaud tweaked Phoenix effect #2 sound to be more accurate matching oscilliscope data. Changed the Phoenix discrete clock rate to a fixed rate of 120000 allowing the simulation to be more accurate with less alaising noise at the cost of speed.

It was some time later until this:

0.122u7: Changed 8085A CPU1 clock speed to 5.5MHz.

0.122u6: Phoenix and clones [Couriersud]: Video timing from schematics, palette from schematics (resnet.h), no more colortable and added save state. Changed visible area to 208x256 and VSync to 61.035156 Hz.

EDIT: My only last question concerns this:

"Walking sound is mixed in via 22k resistors and the other sounds are mixed in via >= 100k."

'Other sounds' is definitely mixed in via >=100k and not 10k?

I ask for two reasons, and I do not mean to insult, but just checking, one, that it is not a typo. Or two, the color bands can be so close in intensity and pattern on the 10k and 100k resistor, that one may have been mistaken for the other.

Regardless, that's it...I promise to stop inquiring now
