Re: Loading files into Xroar....

Just use File->Load or File->Run. XRoar recognises initial $55 (in a file with ".bin" extension) as DragonDOS and parses the header. You should then find it in memory... (FWIW, if it sees an initial $00, it tries it as a CoCo RS-DOS binary instead) Oh, and BASIC files not supported yet... Should pr...

Re: Dragon MMC and AGD games

As your board has a 'special' DOS that uses some code from $E000 on to talk to the AVR, I am sure that we could reduce some 'not needed' DOS commands and fill this area with the code made to send/receive data via AVR. I would like to work on that 'mini-DOS' if you don't mind. Just will need the asm...
