Hi Tony, I would recommend the routine proposed by Tormod. If you have a 64k, the best way is go MAP1 and have the basic and the Orchestra copied to the same adresses but now in RAM, so you can modify anything if you need to. I assume you are planning to do that in XRoar and with the help of GDB, ar...

Hi Tony,
these are the cursors!
One for normal (uppercase) while the other is used to design you are working in lowercase ...
shift+Intro switches from lower-uppercase

Hi Ciaran, I think that nobody needs urgently a patch for that. We have the VDK file as well and it works without problems. But when people wants to use these files in the CoCo-SDC, they need to convert them into DSK because, by now, there you only can use VDK with headers exactly 12 bytes long. And...

Yes, Robert I think so ... These DSK files work with the CoCo-SDC because it seems that the firmware reads the length of the disc file and based on that information calculates the kind of disc, and so knows where the directory begins. If not done and assumed it will begin at sector number 321, it wi...

Hi Robert,
sorry I didn't attach it first time!
Here you will find a 720k disc in both formats:
VDK, this one loads and works flawlessly in XRoar
DSK, that gives IV ERROR when issuing a DIR command

Hi Ciaran, we cannot open DSK files converted from VDK files that are discs 720k long. The VDK work flawlessly in XRoar, but the DSK, that are exactly the same file without the header, always return IV ERROR when entering DIR Is there any constraint that doesnt' admit DSK files longer that 182k? che...

I attach here a small java app that will convert any VDK file into a plain DSK
That way you could use it in the CoCo-SDC for your Dragons

Doesn't seem to be sign related but simply absolute length limited. I have splitted it into two identical halves, then loaded the second to Optimize it and when I have tried to Append the first half it has given the ERROR 1, so it has detected that having half the score loaded, the other half doesn'...

Hi Tony, What you have done gives me a hint about the problem ... Maybe a too long file shows a length word that is taken as a negative one! Just have a look at the CAS converted file, this one has a length of $9381 bytes, you know what I mean ... being greater than $7FFF it becomes a negative value...

Could be an issue of how XRoar manages non standard disks? Maybe you need to run it in CoCo mode instead of Dragon? Hi Robert, great idea. I could, of course, load all of the CAS files into Orchestra in a CoCo Emulation with XRoar and then save them to disc, very good! I will copy the discs later o...
