Bugs (all of these looks BTANBs):
|

|

Sometimes if you attack an enemy when you're at the top of the screen they'll
|
||||
end up landing in an even higher position, and appear over the backgrounds!
|
||||
I think this is just a game bug..

The timer doesn't work (PIC?, RAM Mirror?)

- The timer doesn't work

// then calls setup data and drawing for the timer which is always 20 for whatever reason.
|

|
||||
There are some unmapped writes past the end of text ram too
|
||||
- There are some unmapped writes scattered across different areas (text ram, spriteram, 0xe0000 area etc.)
|
||||
|
||||
- flip screen doesn't work properly,
|
||||
game code explicitly sets flip screen off & the correlated work RAM buffer at 0xee2 no matter the dip setting
|
||||
|
||||
- some service mode items are buggy or not functioning properly;
