-Notes:
-
-- a lower interleave causes some sounds to miss, different interleave values
- change random elements eg position of falling logs, it may be enough to
- synchronise the cpus on read/writes to the 0xdd00/0f range
-
-- it's possible that the two score rows shouldn't be overlaid or shouldn't be
- drawn at all times, the only time there is anything underneath is the colour
- bars on the startup screen
-
-- on odd/bonus levels the chars are not aligned with the sprites when the pylons
- are initially drawn (too low) resulting in the top 3 pylons being black, as
- the pylons move up the screen the chars go out of alignment again (this time
- too high) for a single frame to show another glitch
-
-- front to back ordering of object/enemy sprites appears wrong
-
-- on even levels the front most balloon carrying new enemies swaps between the
- left and middle one, clipping to 16 pixel strips solves this but causes other
- obvious sprite drawing errors
-
-- balloon sprites not displayed on high score entry due to the way videoram is
- being drawn, possibly trying to create a stencil effect
-
-- bursting a balloon on bonus levels just before dying from a log causes a
- sprite glitch for a few frames and then a 9999 point bonus
-
-- reads from 0xffff appear to be a harmless bug in the code that initialises
- memory blocks for enemies on odd levels, it goes on to read from 0x001f,
- 0x003f, 0x005f, 0x007f in the rom before giving up
-
-- a reset while a game is in progress or with credits inserted shows a
- "sorry!! over run" message instead of the test screen during startup,
- looks like the game assumes the reset was caused by the watchdog after a
- hang/crash and is apologising to the player for the loss of their game
-
-- title screen sprite colour glitch in lower right corner of the large pylon
- when an even level was shown before, caused by the game trying to colour
- the top of the pylon in the same way as for odd levels
-
-- enemies stop moving on even levels on rare occasions
-
-- enemy sprites entering from the bridges on odd levels are clipped by a
- few pixels at the top, this would happen even without the overlay as the
- first few rows of videoram are high priority solid chars most of the time
-
-- unknown 0xe002 writes, on for title and level 2 off for all else, looks
- to be graphic related
-
-- bottom of screen is scrappy on odd levels, amongst other things the sprites
- leave early, screen size could be clipped tighter or there could be some
- special handling needed, possibly tied to the 0xe002 writes
-
-- the game freezes in much the same way as the stop dip switch when the coin
- inputs are high (a short PORT_IMPULSE duration will still cause a hitch),
- so potentially there's a coin lockout mechanism
