@ -33,21 +33,19 @@ Stephh's notes (based on the games M68000 code and some tests) :
- Each high-score name is made up of 3 chars.
- There is a "debug mode" ! To activate it, you need to have cheats ON.
- There is a "debug mode" !
Set "Debug Mode" Dip Switch to ON and be sure that "Cabinet" Dip Switch
is set to "Upright". Its features (see below) only affect player 1 !
Features :
* invulnerability and infinite time :
. insert a coin
. press FAKE button 3 and START1 (player 1 buttons 1 and 2 must NOT be pressed !)
. press player 2 button 1 and 2 and START1 (player 1 buttons 1 and 2 must NOT be pressed !)
* level select (there are 32 levels) :
. insert a coin
. press FAKE button 3 ("00" will be displayed - this is an hex. display)
. press FAKE button 3 and player 1 button 1 to increase level
. press FAKE button 3 and player 1 button 2 to decrease level
. press player 2 button 1 and 2 ("00" will be displayed - this is an hex. display)
. press player 2 button 1 and 2 and player 1 button 1 to increase level
. press player 2 button 1 and 2 and player 1 button 2 to decrease level
. press START1 to start a game with the selected level
FAKE button 3 is in fact the same as pressing simultaneously player 2 buttons 1 and 2.
(I've code this that way because my keyboard doesn't accept too many keys pressed)
