  Legendary Wings
  Section Z
  Trojan
  Avengers

  Driver provided by Paul Leaman

To Do:
-   sectionz does "false contacts" on the coin counters, causing them to
    increment twice per coin.
-   clean up Avengers protection; it currently checks against hard-coded program
    counter rather than behaving as a memory-mapped black box.
-   accurate music tempo (audiocpu irq freq)
-   accurate video timing, raw params


Change Log:

FEB-2003 (AT)

- bug fixes:

    avengers061gre: missing sound effects in Avengers
  avengers37b16gre: screen artifacts in Avengers
    lwingsc37b7gre: incorrect sprite clipping in all games

Notes:

  avengers061gre2: corrupted graphics in Avengers' ending not fixed.
  This bug is not in the Japanese set "Buraiken".
  It might just be a bug in the original: the tiles for the character
  image are just not present in the US version, replaced by more tiles
  for the title animation. The tile map ROM is the same between the two
  versions.

  trojan37b1gre: stage 2-1 boss x flip glitches not fixed.
  This could be a side effect of sprite RAM buffering. Suggest buffering
  on-screen content instead of sprite memory.

  Previous clock settings were too low. Sometimes Avengers and Trojan
  could not finish clearing VRAM before a new frame is drawn and left
  behind screen artifacts. Avengers' second CPU was forced to pre-empt
  during soundlatch operations, resulting in double or missing sound
  effects.

/* Avengers runs on hardware almost identical to Trojan, but with a protection
 * device and some small changes to the memory map and videohardware.
 *
 * Background colors are fetched 64 bytes at a time and copied to palette RAM.
 *
 * Another function takes as input 2 pairs of (x,y) coordinates, and returns
 * a code reflecting the direction (8 angles) from one point to the other.
