Funky Bee/Sky Lancer memory map (preliminary)

driver by Zsolt Vasvari

MAIN CPU:

0000-4fff ROM
8000-87ff RAM
a000-bfff video RAM (only 0x20 bytes of each 0x100 byte block is used)
                    (also contains sprite RAM)
c000-dfff color RAM (only 0x20 bytes of each 0x100 byte block is used)
                    (also contains sprite RAM)

read:
f000      interrupt ACK
f800      IN0/watchdog
f801      IN1
f802      IN2

write:
e000      row scroll
e800      flip screen
e802-e803 coin counter
e804      ???
e805      gfx bank select
e806      ???
f800      watchdog


I/0 ports:
write
00        8910  control
01        8910  write

AY8910 Port A = DSW


Stephh's notes (based on the games Z80 code and some tests) :

1) 'funkybee' and clones

1a) 'funkybee'

  - Possible "Lives" settings : 3, 4, 5 or 6 (code at 0x0501)
  - Bonus life routine at 0x2d03 (test on DSW bit 6)

1b) 'funkybeeb'

  - Removal of ORCA copyright on title screen (text at 0x0e9a).
    However, high scores table remains unchanged.
  - Bypass ROM check (code at 0x3ee3)
  - Possible "Lives" settings : 1, 2, 3 or 4 (code at 0x0501)
  - Bonus life routine at 0x2d03 (test on DSW bit 6)

2) 'skylancr' and clones

2a) 'skylancr'

  - Possible "Lives" settings : 1, 2, 3 or 4 (code at 0x0601)
  - Bonus life routine at 0x1ef6 (test on DSW bit 5 !)
    I can't tell if it's an ingame bug or if this was done on purpose,
    but "Bonus Life" settings depend on the starting number of lives.
    DSW bit 6 has no effect because of this.

2a) 'skylancre'

  - Possible "Lives" settings : 3, 4, 5 or 6 (code at 0x0601)
  - Bonus life routine at 0x1f28 (test on DSW bit 6)
