Sorry for no recent updates on Gravity Ball. I got distracted by the
possibility of a 13 character display routine. It displays 13 characters
with no flicker! Unfortunately, there is either a bug in my code or a
bug in the Stella emulator for Macintosh because it is not rendering
Specifically this routine requires that what a write is made to RESBL, the
ball is drawn immediately at the new position (+4 pixels). Based on the
TIA description posted to this list, that is supposed to be the case.
Stella for Mac, however, does not draw the ball immediately but rather
waits to the next line.
Could someone please try the attached binary in the Z26 emulator? Or
better yet, could someone load it into a cuttle cart and see if it
works? It should display the string "13-CHARACTERS" across the top of
the screen followed by a rainbow down the rest of the screen.
I will be happy to share the source code once I get this beast working. I
want to put together a demo program highlighting the display mode before I
release the source.
