The attached program will safely detach DragonDOS before jumping to the 64K mode bootstrap routine on a Dragon 64 or Dragon 200. Use the included BASIC program (MOVE-IT) to copy the program from $0E00-$0E4C to $0200-$024C and save to disk with SAVE"REMDOS64",&H200,&H24D,&H200 . It can then be quickl...

I have uploaded a small program to the Hints and Tips section that will allow you to safely enter 64 mode on a Dragon 64/200 when DragonDOS is present. Enter PCLEAR4 in 64 mode to restore the default 41241 BASIC bytes free.

I recently found the following statement about Eurohard's DragonDOS 4.0 in a review by the infamous Pam D'Arcy of an undisclosed version of SuperDOS on page 10 of the December 1986 issue of Dragon User magazine. Dragon-DOS 4.0 users will still be taking a giant step forward as 4.0 is still littered ...

There is an error in the currently included copies of DragonDOS versions 1.2 and 1.2a. Corrected copies can be downloaded from here.

Due to an error in the online copy of the article " Correcting the faults and problems with Dragondos by Philip G Scott " all previously uploaded versions of DragonDOS 1.2 are incorrectly patched. The error is at Problem 4, 3rd line down. The line reads "+179D 20 DD 12" but should be "+1795 20 E5 12...

The original game uses the address dependent speed poke (POKE65495,0) which can cause some Dragons to crash. Attached below is a copy of the game with the speed poke removed. I have also tweaked the BASIC code slightly to help optimize game speed and improve randomising of the RND() function.

I have uploaded a bug fix release to the Uploads section.

Fixed the bug mentioned here.

The game code is not corrupt, but the key input routines are very poor. Does this game work OK on a real Dragon?

I have just uploaded a fresh copy of this game in the Uploads section.
