Hello Ciaran, one and only one time of the many tests I have done, the POKE&HFF7F,0 has started Orchestra90, by luck for sure. The other times it has just hanged, but calling a hard reset Orchestra90 is started OK. Clearly that software was developped for the CoCo as the keyboard map must be changed...

Hi Ciaran, that's interesting ... I have made the POKE&HFF7F,&H33 to select bank 3 and then DIR works flawlessly, good! But then if I want to start the Orchestra cartridge, I cannot enter POKE&HFF7F,0 to select bank 0 because then the Dragon hangs. Fortunately, while developping my extender, I made ...

Hello, this one loads the DOS and reads the discs as it should, but it doesn't load the cartridge "orch90" xroar -machine dragon64 -extbas d64_1.rom -altbas d64_2.rom -mpi-load-cart 0=orch90 -mpi-load-cart 3=dosPlus -force-crc-match -tape-fast -joy-left 0,0:1:0 -kbd-translate -lp-file ..\XRoar\sorti...

Hi all, I am trying to get XRoar loading a DOS into slot 3 and Orchestra90cc into slot 0, but any other combination would be acceptable as well. I simply don't know what should I do to accomplish that. The longer command I have tried is this one xroar -machine dragon64 -extbas d64_1.rom -altbas d64_...

in fact any key jumped from the orange text to the first working screen.
Couldn't put two 0's at the beginning because the ROM is exactly 8192 bytes long and I have not dared to cut the last two bytes ...

Pressing 'S' after the wrong initiated program, goes to the first screen but the stack has not been moved.
I don't know the possible side-effects of this, but I would prefer to add two $00.
I am going to make this test

Hi Stew, I have added these lines as a new cart in the XRoar config and when I tried it it hangs because it seems to call $C002. The only way to start it right is calling $C000 instead. The first 4 bytes of the program modify the stack: $10 $CE $00 $FA --> LDS $00FA So, skiping two bytes crashes the...

pleased to know you have got it working too ... The way it is programmed seems a bit complicated, but probably we could find hundreds of tunes already made by people in the CoCo arena. Next step is making it work with a DOS cartridge connected (in XRoar) so that we could save our great compositions,...

I didn't look at the two first bytes on the cartridge image. This one has no 'mark' to ask for auto-starting. Basic looks at this 2 bytes and if there is a "DK" then calls &HC002 ant there you go. In this case the program begins right in the first byte, so &HC000 must be called instead. Hope you enj...

Hi,
got it working!

you must enter
EXEC&HC000 instead
The be sure that XRoar is emulating the CoCo Keyboard (or you will be fooled)
Select: Hardware / Keyboard Map / CoCo layout
Then press S, enter and wait for a while
Finally press P and enter to listen to the WillTell overture

cheers
