NOTES:
The main 6502 CPU is a DECO CPU-16. Also, there was some protection
circuitry which is now emulated.
The background tiles had a very ugly encoding. It was so ugly that our
decode gfx routine will not be able to decode it without a little help.
So thats why gfx_expand() is there. Many thanks to Phil Stroffolino,
who figured out the encoding.
If the second player obtains a high score, the game always reads the 2P
inputs for entering initials, even on upright cabinets that lack these
inputs, making it impossible for the second player to enter their
initials. Data East released an update for the EEPROM at location 16A
on the top PCB (CZ00-6A) to fix this bug. They also suggested wiring
the 1P controls to the 2P inputs to work around the issue. The updated
EEPROM has not been dumped.
NOTES ON THE BOOTLEGS:
The bootleg version patched the ROM to get rid of the extra opcode
(bootlegs used a regular 6502), the vectors hard-coded in place, and
also had the protection cracked.
1st bootleg set expects to read vblank status from 0x3800, country
warning sign has been defaced by the bootleggers
2nd bootleg set expects to read vblank status from 0xFFC0, country
warning sign is intact, however Credit is spelt incorrectly.
Stephh's notes (based on the games M6502 code and some tests) :
1) 'exprrada'
- "@ 1986 DATA EAST CORPORATION" + no code to display the Warning screen (World)
- Same way to code number of enemies in "shoot" stages as in 'exprraidu'
(code at 5ce4) and same ingame bug :
5CF4: AD 03 18 lda $1803
5CF7: 49 FF eor #$FF
5CF9: 4A lsr a
5CFA: 4A lsr a
5CFB: 4A lsr a
5CFC: 29 06 and #$06
Correct code shall be :
5CFC: 29 03 and #$03
You'll notice by looking at the tables that there are sometimes
more enemies than in 'exprraidu'.
- Time for each wagon on "shoot" stage is determined by the level
(see code at 0x6834 where location 0x0e is level number-1).
This time is also supposed to be determined by "Difficulty"
settings (DSW1 bits 3 and 4).
There is however an ingame bug that reads DSW1 bits 4 and 5 :
683B: AD 03 18 lda $1803
683E: 49 FF eor #$FF
6840: 4A lsr a
6841: 4A lsr a
6842: 4A lsr a
6843: 4A lsr a
6844: 29 03 and #$03
So Time is also determined by "Demo Sound" setting because of
extra "lsr a" instruction at 0x6843 !
Correct code shall be :
6843: EA nop
Fortunately, table at 0x685f is filled with 0x30 so you'll
always have 30 seconds to "clear" the wagon (which is more
than the time you have in 'exprraid').
For the locomotive, time is always set to 0x20 = 20 seconds
(which is again more than the time you have in 'exprraid').
- "Bonus lives" routine starts at 0xe49b.
- Coinage related stuff starts at 0xe78e.
Coinage tables :
* 0xe7dc : COIN1 - 0xe7e4 : COIN2 (Mode 1)
* 0xe7ec : COIN1 - 0xe7f4 : COIN2 (Mode 2)
- At the beginning of each level, you have text in lower case
which doesn't give you any hints to pass the level nor advice.
- In this version, you always have 5 wagons for the "shoot" stages.
- Continue play is always available but score is reset to 0.
2) 'exprraidu'
- "@ 1986 DATA EAST USA, INC." (US)
- Number of enemies on "shoot" stages is determined by the level
(see code at 0x5d21 where location 0x0e is level number-1).
Note that time tables are coded backwards (locomotive first,
then 5th wagon, then 4th wagon ... up to 1st wagon).
This number of enemies is also supposed to be determined
by "Difficulty" settings (DSW1 bits 3 and 4).
There is however an ingame bug that reads DSW1 bits 4 and 5 :
5D2F: AD 03 18 lda $1803
5D32: 49 FF eor #$FF
5D34: 4A lsr a
5D35: 4A lsr a
5D36: 4A lsr a
5D37: 29 06 and #$06
So number of enemies is also determined by "Demo Sound" setting !
Correct code shall be :
5D37: 29 03 and #$03
- Time for each wagon on "shoot" stage is determined by the level
(see code at 0x6873 where location 0x0e is level number-1).
Note that time tables are coded backwards (locomotive first,
then 5th wagon, then 4th wagon ... up to 1st wagon).
- In the US manual, "bonus lives" settings are told be either
"Every 50000" or "50000/80000".
However, when you look at code at 0xe4a1, you'll notice that
settings shall be "50000 only" and "50000/80000".
- "Coin Mode" as well "Mode 2 Coinage" settings (DSW0 bits 0 to 4)
are undocumented in the US manual.
"Coin Mode" is tested though via code at 0xe7c5.
Coinage tables :
* 0xe7e2 : COIN1 - 0xe7ea : COIN2 (Mode 1)
* 0xe7f2 : COIN1 - 0xe7fa : COIN2 (Mode 2)
- "Force Coinage" (DSW1 bit 6) setting is undocumented in the US manual.
It is tested though via code at 0xe794.
When this Dip Switch is set to "On", pressing COIN1 or COIN2 always
adds 1 credit regardless of the "Coinage" and "Coin Mode" settings.
- At the beginning of each level, you have text in upper case
which gives you some hints to pass the level or some advice.
- In this version, due to extra code at 0xfd80, you only have 4 wagons
for the "shoot" stages instead of 5.
- Continue play is always available and score is NOT reset to 0.
3) 'wexpress'
- "@ 1986 DATA EAST CORPORATION" + extra code to display the Warning screen (Japan)
- This version is heavily based on 'exprrad'
so all comments also fit for this set. The main difference is
The other difference is that you can NOT continue a game.
- "Bonus lives" routine starts at 0xe4e5.
- Coinage related stuff starts at 0xe7d8.
- Coinage tables :
* 0xe826 : COIN1 - 0xe82e : COIN2 (Mode 1)
* 0xe836 : COIN1 - 0xe83e : COIN2 (Mode 2)
4) 'wexpressb1'
- "@ 1986 DATA EAST CORPORATION" + no code to display the Warning screen (World)
- This version is based on 'exprrad' so all comments also fit
for this set. The main difference is that reads from 0x2800
and 0x2801 (protection) are either discarded (jumps are noped
or patched) or changed to read what shall be the correct value
(reads from 0x2801 occur almost all the time).
So IMO this set looks like a World bootleg .
5) 'wexpressb2'
- "@ 1986 DATA EAST CORPORATION" + extra code to display the Warning screen (Japan)
- Modified Warning screen
- This version is based on 'wexpress'
so all comments also fit for this set. The main difference is
the way protection is bypassed (in a different way than 'wexpressb1'
as reads from 0x2801 only occur when a life is lost).
6) 'wexpressb3'
- "@ 1986 DATA EAST CORPORATION" + extra code to display the Warning screen (Japan)
- Original Warning screen
- "CREDIT" misspelled to "CRDDIT".
- This version is based on 'wexpress'
so all comments also fit for this set. The main difference is
the way protection is bypassed (in a different way than 'wexpressb1'
but also in a different way than 'wexpressb2' as reads from 0x2801
occur when you lose a life but also on "shoot" stages).
