Dip locations verified with manual

||||

||||
|

Stephh's notes (based on the games Z80 code and some tests) :
|
||||
|
||||
1) 'dambustr'
|
||||
|
||||
- This seems to be a bugfixed version as only the 3 "fire" buttons are
|
||||
tested while entering the initials (code at 0x1e59).
|
||||
- The "Initials Reset" button only affects the initials, not the scores !
|
||||
- The "Disable Background Collision" Dip Switch only prevents you to lose
|
||||
"lives" if you touch the background : you can still be hit by enemies'
|
||||
bullets and be stalled if speed is too low.
|
||||
- There is a setting which is only available in the "test mode", it's the
|
||||
maximum game time. If you don't set it, the game considers it's illimited
|
||||
time (full doesn't decrease). But once you set it to a value, it is not
|
||||
possible to turn the value back to 0 even by reseting the game.
|
||||
- If you go too far without dying, background becomes complete garbage,
|
||||
but it then appears again correctly. Is there a bad dumped ROM or is
|
||||
emulation bugged somewhere ? Verification against real PCB is needed !
|
||||
|
||||
2) 'dambustra'
|
||||
|
||||
- There is sort of bug at 0x1e59 : you can't enter a letter in the
|
||||
initials screen while pressing one of the system buttons (SERVICE,
|
||||
"Initials Reset", START1 or START2), and even COIN2.
|
||||
This is because 8 bytes are checked instead of 3 in 'dambustr'.
|
||||
- Same as 'dambustr' otherwise.
|
||||
|
||||
3) 'dambustruk'
|
||||
|
||||
- This set is based on 'dambustr' as there is no initials bug (code at 0x1e0f).
|
||||
- The differences with 'dambustr' are :
|
||||
* coinage for 2nd slot
|
||||
* currency and price (but it's still 2 credits to start a game)
|
||||
* score is divided by 10
