E-Types launched

Posted by SpiceWare, in Draconian 30 July 2017 · 362 views

  • Revised station open/close core logic.  Stations will now launch E-Type missiles on later levels (never on Kids, which always has the core open).  There are 2 open/close speeds.
  • Revised Γ (gamma) Levels 
  • Revised Level Data to use less ROM (saved 608 bytes!)
  • Cores now animated at 60fps (used to be 30)
  • Holding down fire at end of game would result in a new game starting up right away.  You must now release fire before you can start a new game.
For the open/close core logic I use sector * difficulty to decide when things will occur. Sector is 0-255 (displayed as 1-256) while difficulty is 0-3 (0=kids, 1=easy, 2=normal, 3=hard):
  // level  KIDS  EASY  NORMAL  HARD
  //  1     0     0     0       0 <- always open for all difficulty levels
  //  2     0     1     2       3 <- start to open/close for Easy, Normal, and Hard
  //  3     0     2     4       6 <- start E-Type on Hard
  //  4     0     3     6       9 <- start E-Type on Normal
  //  5     0     4     8       12 <- faster open/close on Hard
  //  6     0     5     10      15 <- start E-Type on Easy
  //  7     0     6     12      18 <- faster open/close on Normal
  //  ...
  //  12    0     11    22      33 <- faster open/close on Easy

Dropping the attract mode to fit in more samples seems like a good compromise to me. Chris

Have you optimised the sprites with D00d yet - I'm interested to see how much space that saves?

Not yet, been playing in MAME to get a better handle on the spy ship. Also Nathan might be revising the core images due to the 60fps change.
