Hello,
Lately I have adapted 11 text adventures by Channel 8 Software for the Dragon to be used from Disk.
The origin have been the cas files we have in the archive. These are their names
N01 - Golden Baton
N02 - Arrow of Death - Part I
N03 - Arrow of Death - Part II
N04 - Escape from Pulsar 7
N05 - Feasibility Experiment
N06 - The Time machine
N07 - Circus
N08 - The Wizard of Akyrz
N09 - Perseus & Andromeda
N10 - Ten Little Indians
N11 - Waxworks

These adventures only support 'UPPERCASE'
These games were created to be loaded in a Dragon64 after issuing EXEC48000 so entering the mode BASIC64 with the ROM2 at $C000-$FEFF
Doing so, a third tape block was loaded partially in high ram ($8000-$BFFF). These versions do start printing some graphics in the upper half
of the screen. I do not like very much this solution because the graphics use the area where in 'text only' mode we would see the move options
and a room description. You can switch from the 'graphic' screen to the 'text only' back and forth just by pressing INTRO (without any command) To play these games we will issue
- For the CoCo: RUN"RUN ('Only Text' mode allowed)
- For the Dragon:
- text only: RUN"R32
- graphics: RUN"R64
The engine for these games was 'TAPE' oriented, so the save and restore positions are still directed to TAPE.
Keep this in mind if you play them on real hardware!
enjoy!

That's very nice! Thanks Pere!

Nice, if only there were a way to speed up the drawing of the pictures (short of pressing F12 in XRoar).

P.S. The obligatory message - if you need help or further information about these games see the Classic Adventure Solution Archive!

Thanks for the solution page.
I had put all my hopes in the graphics being drawn calling ROM functions, but debugging one of these games
shows that the drawing is done inside the code loaded to $6700 onwards, so still in std RAM where the
double speed POKE for ROM (&HFFD7) would have no effect, pity!
cheers!
