New New Toy

Posted by SpiceWare, 24 September 2017 · 450 views

A little over 8 years ago I'd picked up an Acer Aspire One netbook to replace an old Thinkpad T22.  I set it up with Ubuntu and it worked quite well, though the battery had worn out over the years and needed to be plugged in all the time.
At the start of September I'd moved it, then gently tossed the barrel plug of the power adaptor towards t...

Bonus Lives

Posted by SpiceWare, in Draconian 23 September 2017 · 398 views

Bonus Lives at 20,000 then every 70,000
Jingle added to AtariAge Splash Screen
Disabled collision routines if player is dead as Nathan twice saw the mysterious destruction of station during player's death sequence
Revised formation appearances
* Sector 1  = I-Type only
* Sector 2  = 50% I-Type, 50% P-Type
* Sector 3+ = 37.5%...

Less Chatty

Posted by SpiceWare, in Draconian 20 September 2017 · 448 views

reduced chattiness ("Alert! Alert!" said less frequently)
new gamma level
tightened up formations
don't spawn spy ship, formations, or say "Alert! Alert!" if player is dead (was causing issues when returning to main menu after game over)
Station explosions are now deadly to enemy ships
Revisions to Difficulty Ramp Up
Updates to address screen jitter...

Game Over

Posted by SpiceWare, in Draconian 18 September 2017 · 426 views

additional optimizations by cd-w, saved 600 bytes
Revised P and I type usage:
Kids = max 1 P-Type at a time, zero I-type
Easy = max 1 of each at a time
Normal = max 2 of each at a time
Hard = max 3 of each at a time
Reduced max sprites from 171 to 159, should speed up a number of routines & help reduce the chance of jitter
Revised spy ship routines


Posted by SpiceWare, in Draconian 16 September 2017 · 379 views

applied optimizations from cd-w, which freed up 596 bytes
rewrote enemy spawn routines to use timers instead of random chance.  Still need to work out what the min-max times should be.

Currently at 972 bytes free in the ROM.
For Harmony or Stella (requires Stella 5.0.2 or newer)


Sector Editor

Posted by SpiceWare, in Draconian 13 September 2017 · 549 views

applied Reposition Kernel optimizations from Omegamatrix which freed up 105 bytes
created a sector editor for user submitted Delta levels.
revised the pause screen to show the blinking starfield instead of a black screen with text

At the moment there's 408 bytes free of ROM.
I'd originally planned to try to write the Sector Editor as a w...

Alert! Alert!

Posted by SpiceWare, in Draconian 10 September 2017 · 477 views

Things are getting back to normal after Harvey.  I still need to put my office back together , but decided that can wait until after PRGE if need be.
bunch of optimizations to free up ROM space (about 500 bytes)
cd-w made a slight revision to the CDF driver's 2600/7800 detection logic
added PAUSE support, toggle TV TYPE (2600) or hit PAUSE (7800)....

Logo revised

Posted by SpiceWare, in Draconian 28 August 2017 · 765 views

I'd hoped to get a few more things in place for this build, but my neighborhood's now in the voluntary evacuation zone :
 so I thought it best to make an offsite backup of the current source.
revised logo
menu font revisions
vertical core graphic revised
score luma reduced

For Harmony or Stella (requires Stella 5.0.2 or newer)


Logo downsized

Posted by SpiceWare, in Draconian 21 August 2017 · 536 views

To free up some space for the samples, the logo's been reverted  back to a 48 pixel image.  Replacing the image alone freed up 876 bytes.  The logic and kernel to show 96 pixels was removed for another 714, for a total of 1590 bytes. I also ran the image data through Thomas' DOOD for a savings of 313 bytes.
Besides saving some ROM,...

Spy Ship Sighted

Posted by SpiceWare, in Draconian 20 August 2017 · 452 views

Early support for the spy ship. When it appears "Spy" will be said (I need to free up some space!).
Spy ship will make a number of passes; if it's not destroyed by you, or by something else, the Red-Alert Scenario will be triggered and both I and P type missiles will swarm after your ship. The number of passes is based on the difficulty level:
4 -...
