Stephh's notes (based on the games M6502 code and some tests) :
1) 'exprraid'
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.
