The Hobbit ported to CoCo2 and CoCo3 - DW4 - ENDED!
Posted: Sat Aug 20, 2016 3:08 pm
Hi,
finally I can share with you the 'probably' final version of the port of the game "The Hobbit" from Spectrum48 to 6809-CoCo2
Fortunately, I have worked out a source file that when compiled, produces a binary file that works in a Dragon and in a CoCo2 as well.
It has been a long project, almost two years with a nine months stop gap, so some 15 working months.
You can find all of the info about the project on this web

Note: The web is in spanish language.
The great amount of images uploaded by jltursan has been a nice present, but a pain for this CoCo version too.
The RS-DOS is a bit restrictive and accepts 160k (35 sectors) disk by default.
I have found info that allows patching the RS-DOS versions 1.1, 1.2 and 1.2a so that they work well with 40 tracks allowing for 182k disks as the Dragon DOS.
Despite that, 52 images each 4k requires 208k, so the only way to go is using a compressor. I have chosen Exomizer2 and that way all images fit inside one
disk of that kind (40 tracks)
The program and associated files live in another, standard, disk 160k.
The program has been tested with these Disk Operating Systems (DOS)
RS-DOS1.1, RS-DOS1.2, RS-DOS1.2A
To play, one must use this procedure:
Enter: RUN"PRSD" to make RS-DOS accept 40 tracks
Enter: LOADM"H1":EXEC
And, MOST IMPORTANT, STOP when you get to the Smaug screen. In this moment you have to change the disk in drive 0 and put there the
one with the images (40 tracks disk). The program disk can be used in drive 1 to save games or use another disk.
Only then we should press a key to go on. Obviously, if you want to play text only mode you don't need that disk change procedure.
To see the images collection
Put the program disk in drive 0 and the images disk in drive 1
Enter: RUN"DEMOGFX" and follow instructions
As a reminder, these commands-combinations can make life easier to players
- QUIT and then Break returns to the BASIC Interpreter
- Shift+Left Arrow erases the written command
- the @ sign repeats last command
The program disk has 43 free granules, as each SAVGAM requires 2 granules, we will be able to store TWENTY-ONE snapshots!
cheers
