Donkey Kong Update

[Aspie]

I downloaded the latest update to Donkey Kong today. The official version works fine but now all the alternative versions don't work, they start but are just scrambled graphics. How can I get them back working?

Thanks

The default donkey kong mra has changed so the alternative mra's need to be update to work with the new cre.
I think it will be done soon.

Thanks for that Wark. I thought maybe I had done something wrong or something got corrupted.

Interesting. I didn’t pay attention to the alternates. I will see what we can do.

Thanks Alan !

Did the rom change at all either? I am having some visual rom corruption issues as well. Using the latest dkong rom from my merged mame set shows a different MD5.

[alanswx]

I changed the rom format. Same zip should work I think. The alternatives are still wrong I believe.

What was changed with the DK core?

Sounds are still not right.

Agreed - I just checked it out. I would pay to have the sounds fixed. I plays really close to my original PCB, but the sounds are bothersome.

[alanswx]

Did the sounds get worse or are they the same?

The core is still relying on audio samples, as did MAME prior to 2007. Open the .mra files and you'll see them encoded in there.

Till somebody figures out a way to simulate the analogue audio hardware like modern versions of MAME do, we're stuck with those inaccurate sound effects.

Thanks for the info. Does that include the music / tunes as well? It seems like the timing for the board beginning/end tunes is off. I don’t remember that being an issue in the early versions of MAME.

[jlancaster86]

No, it's mainly the running and jumping effects I was describing. You can download the old MAME samples here if you're curious.

I assume there are various timing issues in the core at the moment are cause for other wonkiness. Honestly, an accurate Donkey Kong core is what I'd love most for MiSTer right now, and I wish there a developer on Patreon I could support for it.

[alanswx]

The core uses a mix of samples and a digital sound board I think. I wonder if it is using the sample for running and jumping.

I agree. The music at the start/end is music is not right.

I'm new on the Mister scene and I'm going to get one when it's back in stock.

The thing is, me and my brother, are building a dedicated DK cab. I would love to see a DK core that has features such as mapping coin and start etc separately. And also I would love to have the sound effects as close as possible and that the highscore is saved!

Is it possible to support the development of the DK core via patreon or something to make it happen in an update?
I'm asking in all humility.

All the best!

Coin and Start seem to be separate:
"J1,Jump,Start 1P,Start 2P,Coin;",
We will get around to trying to add the highscore saving. it is on our list. We are tackling the games hardware with more games on each board first.

[mhartman]

Coin, P1 and P2 are all separate and work great on my cab.

[Robgus]

Thanks for the quick and kind reply! That was really great news (and forgive my ignorance)!

You are all doing amazing work, and if it is possible I would certainly like to contribute to the development of the DK core.

All the best!
