SPECIAL ITEMS
-------------
The game maintains a bunch of counters which keep a record of how many
times you have done various things. Once a counter reaches its
threshold, it is reset to zero and you get the item which that counter
is associated with. Counters are only checked at the beginning of
each round. If two or more counters reach their thresholds in the
same round, the one which is associated with the highest numbered item
is used. The other(s) will keep their value for the next screen. The
counters aren't reset at the beginning of each game, which is why on
the arcade game there is generally a special item on the first screen,
but in the emulation the first game you play doesn't offer a special
item, since the counters are all reset when the machine is first
switched on.
In the following, the ITEM_DATA line contains:
XXXX ( AA BB CC DD ) EE
XXXX is the address of the counter which is used
AA BB CC and DD are the 4 possible thresholds which the counter must
reach before you get the item. Which one of the 4 values is used
depends on the 'difficulty' setting that the game is currently running
at:
CC for difficulty 00-04
DD for difficulty 05-07
BB for difficulty 08-0B
AA for difficulty 0C-1E
initial difficulties are: 0D (v.hard), 0A (hard), 04 (easy) and 07
(normal) for the 4 dip-switch settings. The difficulty changes
throughout the game, going higher when you gain extra lives, lower
when you die, and other things affect it, too, which I don't know
about.
EE is non-zero if the bell should warn us that the item is around
The ITEM_ACTION sections (where I've put them in) are useful for
'cheating' in MAME. Where it's like 'IX+$31', the address is E691+31
for P1 and E6C3+31 for P2. So, for example, a cheat would be:
boblbobl:0:e6f4:80:0:Long Range Bubbles (P2)
because e6c3+31 is e6f4.

19-or-more times for the different types of potions
If bubble'n jumps on the top step, he appears from the bottom for a

not)

FIREBALL BUBBLE
---------------
The fireball bubble appears from an air vent of top (or bottom) of the
screen. You get 100,000 pts. when you break it.
The bubble has same effect as red cross, but the effect of this item
continues for 5 rounds! Namely, bubble'n can blow 16 fireballs in
each round.
It appears that the fireball bubble is randomly created. Whenever a
bubble floats onto the screen, there is a 1 in 4096 chance that it is
incarnated as a fireball bubble. It looks as if at some point in the
design of the game it was intended for this kind of randomness to
happen more, since there is a routine which implements randomness with
a whole bunch of preset odds:
ID odds ID odds
01 1 in 1
03 1 in 2 19 1 in 64
05 1 in 3 1B 1 in 128
07 1 in 4 1D 1 in 256
09 1 in 5 1F 1 in 512
0B 1 in 6 21 1 in 1024
0D 1 in 7 23 1 in 2048
0F 1 in 8 25 1 in 4096 (default)
11 1 in 9 27 1 in 8192
13 1 in 10 29 1 in 16384
15 1 in 16 2B 1 in 32768
17 1 in 32 2D 1 in 65535
the odd thing is, though, that the routine is only ever used with an
ID of 25, and only for the fireball bubble. This table can be used to
'tune' the rarity of the fireball bubble, by altering the content of
location 6e30 of CPU 0. MAME provides a convenient way of doing this,
with its 'cheat' mechanism.
MAME BOBLBOBL CHEATS
--------------------
First edit the 'cheat.dat' file, and add lines like this:
boblbobl:0:6e30:01:0:fireball bubble - always!
boblbobl:0:6e30:07:0:fireball bubble - 1 in 4
boblbobl:0:6e30:15:0:fireball bubble - 1 in 16
boblbobl:0:6e30:1d:0:fireball bubble - 1 in 256
then run MAME using a command line like this:
mame boblbobl -cheat
then you'll find there's a new menu entry on the gui, called 'cheat',
from which you can select the frequency you want!
Here's a bunch of other cheats that I've played with - just a random
selection that happen to be in my cheat.dat file - some are more
useful than others, and most of the spoil the fun of the game...
