Hello Stew,

- With your one LEAS per line, I think there's enough time to copy 160 lines.

In fact I am using 4 x LEAS for every screen line because I am moving that pointer

thanks in advance

Hi Stew and Steve, Thanks a bunch for your ideas, they are really great! As I have said, I have no problems moving the main character and it changes location very often and, by now, Dragon DOS seems to be fast enough loading every screen. I was thinking that maybe the last screen should appear one-s...

Hi, thanks a lot for these ideas, Steve. In fact I have no problems updating the screen while moving the main character, I was just trying to load a whole screen from disk and show it the next frame.

I have been tinkering with the idea of copying a graphic screen while the RAM is not accesible to the VDG (after the end of each frame) and so, I have coded this small routine, but the cycle counting that I get is far too big to do that ...

Just one question, How did you make the DOS calls? If you correctly used the jump table at the beginning of the DOS ROM, then this should work on the DragonMMC's DOS emulation. Cheers. Phill. Hi Phill There are quite a lot of calls due to the program compatibility with CoCo2-3 and Dragon64 IIRC onl...

Something must be wrong. I've an ordinary CoCoSDC and not only one normal sd card fits into the slot. Only the thin MMC SD fits and make "click". What da hell? Crap ... There's a normal "SD Card Module" on this CoCoSDC ... i'm really confused. The seller bought this one from Ed. It is very strange ...
