if you have any questions about the Acorn Atom, please post them here so that I can see them.
You can find a disassembly of the #Fxxx rom here: http://www.acornatom.nl/atom_handleidin ... m/f000.txt
$FE71 reads a key from the keyboard matrix from bottom left upwards and then the next column upwards, if nothing is pressed then 255 is returned.
So SPACE returns 0, RETURN returns 13, etc.
thanks a bunch!
I have downloaded the whole unasembled ROM for the Atom Acorn and have seen these subroutines, great!
I saw that the comments here seemed to point to the new (and better) version for Windows (v0.7), but as a Dragon user, I would
prefer to convert the 150 games already created with the old version. Once done, we will see how easy it would be to 'add' the new
By now, I an converting the whole FOGGY.ASM that way I will end up with a 'new' game for CoCo-Dragon and as a side effect we will have
the engine almost converted (the functions used in FOGGY), so the more games we can convert, the more finished will be the engine ...
With the friends of Retrowiki, we have a thread opened there to comment about it
Anyway, I am attaching here three images that show the FOGGY menu on the Speccy4.8 emulator and then the images in PMODE4 on XRoar for
the Dragon and the CoCo too.
One of the Retrowiki colleagues is going to work to convert text and sprites to PMODE3 ...
