additional information
info 0.111u3 [Pierpaolo Prazzoli]

WIP:
  • 0.124u1: Added Discrete sound. Changed visible area to 224x768 and palettesize to 32 colors.
  • 0.111u3: Pierpaolo Prazzoli added Monster Zero (Nihon 198?).
  • 23rd May 2005: Pierpaolo Prazzoli - Monster Zero (Nihon Game 1982) has a weird protection which seems to test some values from program code, but it also seems to provide extra code to extra ram which will probably need a trojan to extract it.
  • 10th April 2005: Tomasz Slanina - First look at Monster Zero (Scramble hardware with few additions like extra RAM ).
