@Rolf Michelsen Hi Rolf, I wanted to use your utility DragonDos to add some 60 files to a VDK image In fact I will have to do that more that 25 times with different files! I wanted to avoid writting the full name of all of the files, so I tried Dragondos -v write PACK.VDK *.BIN but it doesn't work, ...

Hi Tony, I think that if you fill these system variables on entry ($23,$25,$27) it should work as long as you set the new stack under the new reserved string space and then go back to basic by jumping to $8371 Ideally you should disable interrupts before changing variables and then enable them befor...

glad to know,
you are welcome!

Hello Tony, I wrote the header and trailer that are the CoCo standard. XRoar loads them into a Dragon emulation with no problems. But if you wanted to add the Dragon std Header (no trailer) It has this structure: Byte 0 -> always $55 byte 1 -> $02 for Binary files bytes 2-3 - Load Address bytes 4-5 ...

Hi Tony, it needs a 5 bytes header and a 5 bytes trailer at the end The Header is: - byte 0 -> always $00 - bytes 1-2 -> The Length of the file - bytes 3-4 -> The Load address And the trailer: - byte 0 -> always $FF - bytes 1-2 -> by now $0000 (maybe intended for Stack value before execution ...) - ...

Hi Tony, thanks a lot for your kind words. honestly if you don't have a four drives setup ... you don't need to worry about this last update. It is just a consistency bug correction. In fact it just involved moving 3 'control code lines' so that they take effect at the right moment. So don't expect ...

Hello, along this time (a bit more than a month) no feedback received, so it is not used by nobody or it seems to be enough stable. I know that Ed Snider (Zippster) is including this ROM in a bank of the CoCo-SDCs he is selling. There are some users that show up in FaceBook ... 137 members now and g...

Hi Ciaran, I explained it wrongly. Both Dragon and CoCo start alright, without problems with the -gdb option. What surprised me was that, if I used any of these machines without the option -machine-cpu 63909 then GDB shows the message "Register 9 is not available" and the two windows I wanted to see...

One more comment. The first try, I had everything correct using these commands: start xroar -gdb -machine cocous -bas bas14.rom -extbas extbas11.rom -machine-cart mpi -mpi-load-cart 3=rsdos -mpi-load-cart 0=or90S1T0 -mpi-slot 3 -force-crc-match -tape-fast -joy-left 0,0:1:0 -kbd-translate -lp-file .....

Hi Tormod,
I have added the -gdb in the xroar command and then sent the m6809-gbd
It works or seems to work now ... I will make som tests

Strangely with Dragon emulation I have never put this -gdb in the xroar command and it
works perfect for me.

thanks a lot for the advice!

cheers
