I guess people do NOT read krikzz comments on first page

Quote from: krikzz
Mega-ed v1 support stopped few years ago
and i have no any plans to work over updates for v1.

Also this update will not fit in mega-v1,

At the moment FPGA used on 96% on mega-v2

X3 and X5 not supports FPGA core update.
and they even don't have audio outputs,
so, this update possible only for v2/x7 users.

I would still really like to know about the volume imbalance issues and if that is hardware related or not and if it could be fixed in a future update?

Hello all,

I have prepared a new test FPGA core for you:

http://s000.tinyupload.com/?file_id=41594430196977865685

It fixes a serious bug in the rhythm note trigger function (which, obviously, has been missed by most people  :P ;) ).

The ryhthm tracks of most games should now sound correctly. Most notorious example is Out Run.

Please note that this is a test core wil limited feature set. Only krikzz can do fully feratured cores.

BR,

Necronomfive

Has testing on this one gone OK, and if so, any word on when this fix will be integrated into a fully featured core? I see 3.04 was officially released on the 12th, so presumably doesn't include this.

Keen to start an FM Phantasy Star playthrough on an official core, but don't want to do so while there are still known bugs in the FM driver.

Cheers again for all your work!

I did notice the buzzing in Outrun (and a similar thing happened with games with the Namco sound chip on Everdrive N8) in 3.04, but was afraid to mention it due to my stupid outburst. I also feel it was rude to imply that I don't know how to hook my console correctly. I have the system hooked up via the SEGA CD stereo for the games that use it and usually switch to the native audio for non-CD games. People make mistakes!

Yes so did I.  As you start a race and as you enter the next level also. The noise disappears when you drive off road. Strange....

Not strange at all, even Tim SMS FM boards pre 2.2 have the same issue (and that's all HW):

http://etim.net.au/smsfm/smsfm.html

"In late 2014 there was some extra details discovered about the Japanese SMS sound hardware on detailed in this thread. The benefit is there are no longer 'extra' sound effects playing in Outrun at the start of a race."

http://www.smspower.org/forums/14998-SonicFMHackEnablingPSGFMMixing

Basically non Jap SMS need to be timed carefully wrt Outrun and its use of mixed FM/PSG, Tim made a fix on board v2.2 so I suppose it's possible to fix the necronomicom core as well if he has the time/energy .... but it is really only one game and to be fair the MD version is much much much better.

So then, how come my findings and issues are considered unimportant/insignificant and met with resistance, yet a tiny sound imperfection in Outrun was found to be significant enough to be worth addressing?  According to you, this was just a labor of love and that you are under no obligation to do any improvements.....

In all seriousness, I am just wondering why my concerns/findings aren't met with the same response as others?  What did I say or do that was so different from anyone else?  I simply wanted to know what the story was on the volume imbalance between FM and PSG...

Addressed?

Where did you get that from?

Also I doubt your bickering helps your cause. If necronomicom says he's fine then the core is done as far as he is concerned, given it was done for free I'd say enjoy it and move on.

Bump - @Krikzz, any plans to put this bugfixed core into a Mega Everdrive OS 3.05 update?

I started the Phantasy Star playthrough anyway ;D Absolutely loving the FM!

I just uploaded test build of new os v3.05rc1.  http://krikzz.com/pub/support/var/rc/mega-ed/MEGAOS-V3.05-RC1.zip
Features list:
1)Fixed YM2413. Latest update from Necronomfive
2)Changed controllers detection code
3)Fixed possible micro freeze when exit from Options menu.
4)File sorting option. Folders with more than 256 files will not be sorted
This OS version will resets setting to default, so backup your saves from last played game

Sweet!
Now we just need that built-in X7 DAC to be activated so we can listen to those sweet tunes on Genesis 2 / Mega Drive 2 without that nasty distorsion!  ;D
