|

Note: Protection MCU is labelled "TS" without a number and without a coloured
|
||||
stripe. Maybe its code is not region dependant.
|
||||
Note: Euro rom labels (IE: "TSE") had a blue stripe, while those labeled
|
||||
as USA (TSU) had an red stripe on the sticker. The intermixing
|
||||
of TSE and TSU roms in the parent set is correct and verified.
|
||||
Note: Euro set simply states the game cannot be operated in Japan....
|
||||
Note: These issues have been verified on a real PCB and are not emulation bugs:
|
||||
- misplaced sprites ( see beginning of level 1 or 2 for example )
|
||||
- sprite / sprite priority ( see level 2 the reflectors )
|
||||
- sprite / background priority ( see level 1: birds walk through
|
||||
branches of different trees )
|
||||
- see the beginning of level 3: background screwed
|
||||
- gray tiles around the title in Top Secret
|
||||
BTANB [MT00209] (verified on real PCB):
|
||||
- misplaced sprites (see beginning of level 1 or 2 for example)
|
||||
- sprite / sprite priority (see level 2 the reflectors)
|

- sprite / background priority (see level 1: birds walk through

|
||||
- see the beginning of level 3: background screwed
|
||||
- gray tiles around the title in Top Secret
|
||||
|
||||
Note: The MCU rom contains the string
|
||||
"<for dealer-location test & USA show. 87/03/10 >"
|
||||
which indicates it could be from an earlier version, especially with it
|
||||
coming from a 'Top Secret' bootleg with identical program but unprotected
|
||||
MCU, however f1dream has a similar string, and is verified as being from
|
||||
a production board.

of TSE and TSU roms in the parent set is correct and verified.
|
||||
- Euro set simply states the game cannot be operated in Japan.
|
||||
- IRQ 4 is control related. On each interrupt, it reads 0xFE4000
|
||||
(coin/start), shift the bits around and move the resulting byte into a
|
||||
dword RAM location. The dword RAM location is rotated by 8 bits each time
|
||||
this happens. This is probably done to be pedantic about coin insertions
|
||||
(might be protection related).
|
||||
|
||||
ToDo:
|
||||
- Proper IRQ2 (should be LVBL) and IRQ4 (V256) hookup
|
||||
TODO:
|
||||
- Firing IRQ4 at line 16 causes the game to often miss coin inserts. Set
|
||||
to 128 currently to compensate.
|
||||
- The game doesn't set the coin lockout in service mode, so the coin inputs
|
||||
can't be tested there if you uncomment and enable it.
|
||||
|
||||
About IRQ:
|
||||
IRQ4 seems to be control related.
|
||||
On each interrupt, it reads 0xFE4000 (coin/start), shift the bits around
|
||||
and move the resulting byte into a dword RAM location. The dword RAM location
|
||||
is rotated by 8 bits each time this happens.
|
||||
This is probably done to be pedantic about coin insertions (might be protection
|
||||
related).

This board handles tile/tile and tile/sprite priority with a PROM. Its
|

working is complicated and hardcoded in the driver.
|
||||
|
||||
The PROM is a 256x4 chip, with address inputs wired as follows:
|
||||
|
||||
A0 bg opaque
|
||||
A1 \
|
||||
A2 | fg pen
|
||||
A3 |
|
||||
A4 /
|
||||
A5 fg has priority over sprites (bit 5 of tile attribute)
|
||||
A6 fg has not priority over bg (bits 6 & 7 of tile attribute both set)
|
||||
A7 sprite opaque
|
||||
|
||||
The output selects the active layer, it can be:
|
||||
0 bg
|
||||
1 fg
|
||||
2 sprite
