0.111u3 [Pierpaolo Prazzoli]


WIP:

- 0.145u6: hap added preliminary protection emulation to Monster Zero. Note: The initial protection routine is on the maincpu at $c591-$c676. It accesses the 8255, expects an irq, and reads $d800 256 times which is xored against data starting at $0100 to confirm a checksum stored in $0011-$0019. Then it reads the (presumably)same block to store it in RAM at $3800-$3fff. 9 blocks in total. It is presumed that this data comes from another ROM, and scrambled/encrypted a bit. The data(code) in the extra RAM is later jumped/called to in many parts of the game.

- 0.132: Tafoid and Fujix changed year to 1982 (Arcade TV Game List book).

- 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 ).
