I know very little about the Cumana and Delta disk systems. My current basic knowledge of these systems is as follows: DragonDOS Controller + DragonDOS/SuperDOS (THE BEST) Cumana Controller + CumanaDOS = DragonDOS compatible (GOOD) Delta Controller + DeltaDOS = NOT DragonDOS compatible (JUNK) I woul...

Here are a couple of screen shots. The first screen shot shows the latest snapshot (xroar-snap-2014-05325-w32) with the Telewriter (.dmk) disk. The second screen shot shows the older snapshot (XRoar snap-20130309-w32) with the exact same copy of the Telewriter (.dmk) disk. The same thing happens whe...

Thanks.

You might have to restrict yourself to using DMK format disks, I don't know any way of signalling single density in the other formats. If I create a new disk test.dmk, I'm able to INIT A, save to it, etc. That doesn't work for me using the Win32 version under Windows XP Pro. The same test works per...

Most machine code programs (games) have an EXEC address which is different to the START address. A typical example is: START ADDRESS = $0C00, END ADDRESS = $7000, EXEC ADDRESS = $4000. The DeltaDOS manual states that the SAVEM command only accepts a START and END address (SAVEM"NAME",START,END). How...

DeltaDOS emulation is not working correctly. Trying to read or write to virtual disk results in DeltaDOS returning a NOT READY ERROR or SEEK ERROR.

I'm using the latest snapshot version (xroar-snap-2014-05325-w32.zip).

Here is an improved auto-running DOS compatible version. Follow the previous instructions for saving to disk.

Here is a DOS compatible auto-running machine code version.

Here in an alternative version of Steve Woolham's Speedkey routine. This updated version is also compatible with all known versions of CoCo and Dragon DOS (The original SpeedKey routine is not compatible with HDB-DOS). 10 GOSUB 10000 20 END 10000 ' ENABLE SPEEDKEY 10010 IF PEEK(269)+PEEK(270)<>1 THE...

Here is a further improved version of the game. Changes made to this version: * Size optimized the game code to help save memory and optimize game speed * Greatly improved keyboard response by adding Steve Woolham's Speedkey routine * Added X=RND(-TIMER) to make each new game as random as possible *...
