reboot delayed

Posted by SpiceWare, in Draconian 02 April 2017 · 370 views

Last time around cd-w made a comment that led me to doing a test rewrite of one of the ball reposition kernels:

resizable ball

Posted by SpiceWare, in Draconian 29 March 2017 · 235 views

Kernel revisions panned out - the ball object can now be resized and recolored.
The draw missile routines haven't been updated yet to use the ball as a last resort, so to test the resizing I've temporarily modified the stars to have different widths.  I also added some missiles that fly around in a formation just below the enemy formation...

The ball reposition kernels have been rewritten, the starfield has been reimplemented, and you can fly around the sectors.

ROM requires Harmony or Stella 5.0.0-pre6 or newer.

missile engine back in play

Both missiles are being used to draw all the objects. You can move one of them around with the joystick. Position within the world will be shown using the score as well as in the radar.

Like the sprites, I had to add an extra scanline of delay after the reposition occurred else the top scanline of the missile would disappear when it was po...

sprite engine back in play

Both players are being used to draw all the sprites.  At the initial position there will not be any flicker.

The blue test sprite can be moved around with your joystick, the score is used to show your X and Y position.  Hold fire to slow down the movement.

During tests I did discover a minor issue, which was most likely present...

Progress on game screen

Posted by SpiceWare, in Draconian 18 March 2017 · 235 views

Player0 and Player1 reposition kernels have been rewritten, but are not yet being tested so the test pattern goes straight down.  Still need to redo the reposition kernels for the missiles and ball.
The score/radar/lives/formation routines are functional.  If you change the QUADRANT and/or SECTOR in the menu the correct station layout wil...

menu's back in place

Joystick up/down selects menu option, joystick left/right/fire changes value.  
We've figured out a way to do NTSC vs PAL detection , so I've set it up so TV-TYPE will be automatically set.
The START option is currently overwritten to display detected console on the left, and timer value on the right.  The timer value is used for t...

The development of Bus Stuffing took far longer than I expected. While the results are awesome:

Two million pounds of ice on a subtropical island!

My sister likes to bring my nephew and a few other kids for an extended weekend to do some holiday sightseeing in Houston. I try to find something different to do every year, and this year was no exception!
They got here on Saturday, the 17th, and we started them off making Melted Snowman Cookies: 
bake sugar cookies

extra hardware!

Received a question via Messager that I'm going to reply to here as others may find it interesting as well:
Long story short, extra hardware in the cartridge.  
Short story long, one or more of the following are added into the cartridge:

Extra ROM
When the Atari was designed ROM was expensive so they only...
