Stephh's notes (based on the games Z80 code and some tests) :
- DSW1 bits 0 and 1 determine the "Bonus life" value (1 OFF - 0 ON) :
* ......11 : 10000 points
* ......10 : 20000 points
* ......01 : 30000 points
* ......00 : 40000 points
- DSW1 bit 2 determines the "Bonus life" occurence (1 OFF - 0 ON) :
* .....1.. : many extra lives can be awarded every "value" points
* .....0.. : only one extra life can be awarded at "value" points
- When DSW1 bit 3 is OFF, you can't get any extra lives (code at 0x3368).
- I've decided to merge these 4 bits in a single choice for the end-user.
- Credits are coded on 1 byte (0xc6bd) then are divided by 2 for display
so it can display 1/2 credits when coinage is set to 2C_1C or 2C_3C.
Surprisingly, due to code at 0x2f77, credits are limited to 15 when
coinage is set to 1C_1C or 1C_2C and to 14 1/2 is set to 2C_1C or 2C_3C.
- Level is stored 1 byte (0xc70c), range 0x00-0x07 (code at 0x071d and 0x072c).
This means that if you complete level 8, you'll restart from level 1
with its initial difficulty (based on the Dip Switch settings).
