Today's WIP from git is wonderful.
Dragon 32 working and 64 on the way.
Loading tapes from OSD as well.

I like this core. Very nice work, thkx to alanswx and pcornier. Amazing.

Cool. I would like to test Dragon loading.
I have a CASdunio that I used with my Dragon64 for loading tapes.

Where was Dragon Core? Or is it a selection within Alice Core?
Thanks

Take a look at the new CoCo2 and Dragon32 core. Not sure why the Dragon 64 doesn't work. Any help with that would be appreciated. Just run the updater.

CoCo2 and Dragon32 works fine.
CoCo2 TAP Loading works well, Dragon32 some tapes still refuses lo load correctly.
Dragon64 keyboard does not work.
Reset is weird, doesn't matter if you reset with ALT-CTRL-ALTGRAPH, seems to work.

You're really close, what about disk controller ?

There are some parts and pieces for the disk controller. We need to work on that.

Is audio in connected? I tried loading some tapes via my tape loader and nothing seems to be read by the MiSTer.
After I type CLOADM"" I get a high pitched noise, which I can still hear now everything is switched off ;)

The tape loading only looks at the game folder on the SDCard at this time.
Maybe ADC support will come in future, but probably disk support will come before that (but it's not trivial, so no estimates on timeframe)

@dshadoff,

The ADC support has also another advantage, some cartridge need to have access to the audio in to work. The amazing Audio Spectrum Analyzer (cat. N°:26-3156) in one example. From my point of view (being moreover an user of this cartridge :-)) this feature is a quite important one to have as it will prevent to use a software, not to run it of course, but to use it.
Anyway thank you for your hard work on this beloved core

Thank you guys so much for this core!!!
The Dragon32 was my first computer and I've wanted a core for it ever since getting my MiSTer
I'll be spending quite a lot of time with this core.

Thanks again, it's very much appreciated

Just tried the latest core and more and more games are working fine.
However I notices a graphic issue with Speed-Racer, don't know if it is my dump or an issue with the core but it hang after the track selection.

I had the same problem. I think the tape didn't work on xroar, but the disk did.. maybe not until we get disk support working.

I have some issues with defining my gamepad buttons. it seems that only the horizontal axes from the analog stick are working, not up and down. will there be a digital pad support coming too?

Did you configure the Stick X: Tilt Right and Stick Y: Tilt Down when configuring your controller from the MiSter Main menu?
Here is a quick video configuring my PS controller.

It's something we'd like to do, but there is a lot of work involved in implementing any feature, most importantly obtaining good technical information about the machine. And there are lots of other important things to add (and fix) before we start on the CoCo3.

Perhaps it's better not to talk about CoCo3 until after CoCo2 has disk support (which will probably take a while).

Yes, this caused me problems too; I even ended up getting a new controller because I had thought it was my controller.

I don't know why the analog stick settings take place AFTER settings for mouse. (And especially after one has already tilted the stick in the early part.) There are a few points in that process where you might think that you are done, before even getting to the analog stuff.

But, I'm pretty sure that you just didn't set up the stick completely yet.

Regarding joysticks, when I had my Dragon I built a digital to analogue converter to use Atari standard joysticks.

I am sure there are Dragon games that play better with analogue but many are Spectrum ports, that I found worked better with normal digital controls, plus my Dragon joystick was like a stick in a bucket! Modern thumbsticks are a dream! :)

Hi Higgy !

I've got an analog joystick and works fine with this core. Original one is based on potentiometers, like Apple ][ and own CoCo.

Thanks dshadoff & NML32 for helping me out getting my gamepad mapped correctly. now all the analog axes of my controller (ps4) work fine. I own a Dragon 32 and the original controllers are indeed analog but non self-centered, a feature modern analog controllers unfortunately don't have.
I think not all users have gamepads with analog sticks so this core will get many questions how to map the directions. Maybe in future there will be some option to also set the dpad as the left analog stick, so you could use both ways.

Back to speed-racer, I found the Microdeal K7 version (Dragon 32) and the game works on the Coco2 core.
I've now serious doubts about the validity of the dump of the K7 game that I found for the coco2.
Great news then.

I am glad you tried the Dragon version. I noticed that the cassette I had wouldn't run on xroar. But the disk version would. I didn't try the Dragon version. I suspect the cassette might be bad.

Here are two nice add-ons to add to the Mister running with the Coco2 core for those who maybe want to put the Mister in a real Coco case

I'm just wondering if the real analogue joystick could work with the Coco2 core

And if you want a CoCo keyboard to go with that USB converter... look here (but he runs out of them quite frequently):

Higgy, if you have a CASduino, could you run a test for me ?
Please try playing the output into the ADCTest core, with the "3.3V" scale, and take a screenshot. (Please play CoCo format)

I am wondering whether that device is AC coupled or not (it should be), and whether the amplitude is within spec.
This will determine whether it can be used with the ADC as-is. In building my own CoCo-type virtual cassette player (different design), I have met issues like these, and adjusted my design accordingly.

If it's correct, the waveform should be roughly in the middle of the scale, without touching either edge.
If you see only half of the waveform, but centered on "zero", that would indicate DC coupling.

No problem. I will have a go.
Funny I was on their website yesterday and spotted that they had updated the CASdunio firmware. I will test before updating firmware and again after updating.
