Funny Bubble ...

It's a Puzzloop (Lup Lup Puzzle) rip-off .. but with two Z80 CPUs

The program roms say omega 1997
  Omega made Super Lup Lup Puzzle/Lup Lup Puzzle/Puzzle Bang Bang see vamphalf.c
  These games copy the game play of Puzzloop but add adult picture backgrounds.

The gfx roms say 1999
Title screen has no date

( a z80 as the main cpu in 1999 ??! )

Did In Chang Electronic Co do the "original" version of Funny Bubble?
 Comad either hacked or licensed it.  As "In Chang Electronic" are
 spelled out in the default high score table ;-)
