17 ToDo:
18 - sidepcktj: Intermission screen's background for player 2 is completely screwed (Cause is currently unknown)
19 
20 
21 Stephh's notes (based on the games M6809 code and some tests) :
22 
23 1) 'sidepckt'
24 
25   - World version.
26   - Credits are BCD coded on 1 byte (range 0x00-0x99) at location 0x0007.
27   - Bonus lives settings don't match the Dip Switches page : even if the table at 0x40af (4 * 2 words) is good,
28     there's a ingame bug in code at 0x4062 :
29 
30       4062: CE 40 AF         LDU   #$40AF         U = 40AF
31       4065: F6 30 03         LDB   $3003
32       4068: 53               COMB
33       4069: 54               LSRB
34       406A: 54               LSRB
35       406B: C4 0C            ANDB  #$0C
36       406D: EC C5            LDD   B,U            U still = 40AF
37       406F: 33 42            LEAU  $2,U           U ALWAYS = 40B1
38 
39     So 2nd and next extra lives are ALWAYS set to 50k+ regardless of the Dip Switches settings !
40   - Player 2 controls are never used ingame for player 2 due to extra code at 0x5a35 :
41 
42       5A2E: 96 1A            LDA   $1A
43       5A30: 84 01            ANDA  #$01           A = 00 for player 1 and 01 for player 2
44       5A32: 8E 30 00         LDX   #$3000
45       5A35: D6 CA            LDB   $CA            B ALWAYS = 01 due to initialisation of $CA at 0x43f4
46       5A37: C5 01            BITB  #$01
47       5A39: 26 02            BNE   $5A3D          always jumps to 0x53ad
48       5A3B: 30 86            LEAX  A,X            this instruction is NEVER executed
49       5A3D: A6 84            LDA   ,X
50 
51   - Player 2 controls are also never used for player 2 when entering initials due to extra code at 0x8baf :
52 
53       8BAF: 96 1A            LDA   $1A
54       8BB1: 84 01            ANDA  #$01           A = 00 for player 1 and 01 for player 2
55       8BB3: D6 CA            LDB   $CA            B ALWAYS = 01 due to initialisation of $CA at 0x43f4
56       8BB5: 27 02            BEQ   $8BB9          never jumps to 0x8bb9
57       8BB7: 86 00            LDA   #$00
58       8BB9: 8E 30 00         LDX   #$3000
59       8BBC: A6 86            LDA   A,X
60 
61   - Screen never flips ingame or in "continue" screen for player 2 due to code at 0x662f :
62 
63       662F: 0F 0A            CLR   $0A            $CA = 0
64       6631: D6 1A            LDB   $1A
65       6633: 27 00            BEQ   $6635          continue regardless of player
66       6635: CC 00 00         LDD   #$0000
67 
68       75DF: D6 0A            LDB   $0A
69       75E1: F7 30 0C         STB   $300C
70 
71     Surprinsingly, the screen might flip for player 2 after GAME OVER due to original code at 0x4de8 :
72 
73       4DE8: D6 1A            LDB   $1A            A = 00 for player 1 and 01 for player 2
74       4DEA: 27 03            BEQ   $4DEF
75       4DEC: F7 30 0C         STB   $300C
76       4DEF: C6 20            LDB   #$20
77 
78 
79 2) 'sidepcktj'
80 
81   - Japan version.
82   - Credits are coded on 1 byte (range 0x00-0xff) at location 0x0007, but their display is limited to 9.
83   - Same bonus lives ingame bug as in 'sidepckt'.
84   - Player 2 controls are always used ingame for player 2 due to code at 0x58ab :
85 
86       58AB: 96 1A            LDA   $1A
87       58AD: 84 01            ANDA  #$01           A = 00 for player 1 and 01 for player 2
88       58AF: 8E 30 00         LDX   #$3000
89       58B2: A6 86            LDA   A,X
90 
91   - Player 2 controls are also always used for player 2 when entering initials due to extra code at 0x8b9f :
92 
93       8B9F: 96 1A            LDA   $1A
94       8BA1: 84 01            ANDA  #$01           A = 00 for player 1 and 01 for player 2
95       8BA3: 8E 30 00         LDX   #$3000
96       8BA6: A6 86            LDA   A,X
97 
98   - Screen always flips ingame or in "continue" screen for player 2 due to code at 0x662f :
99 
100       6473: 0F 0A            CLR   $0A            $CA = 0
101       6475: D6 1A            LDB   $1A            A = 00 for player 1 and 01 for player 2
102       6477: 27 04            BEQ   $647D          jumps if player 1
103       6479: 86 20            LDA   #$20
104       647B: 97 0A            STA   $0A            $CA = 0x20
105       647D: CC 00 00         LDD   #$0000
106 
107       75A0: D6 0A            LDB   $0A
108       75A2: F7 30 0C         STB   $300C
109 
110     After GAME OVER, code at 0x4d16 is slightly different than in 'sidepckt' :
111 
112       4D16: D6 1A            LDB   $1A            A = 00 for player 1 and 01 for player 2
113       4D18: 27 07            BEQ   $4D21          jumps if player 1
114       4D1A: C6 20            LDB   #$20
115       4D1C: D7 0A            STB   $0A            $CA = 0x20
116       4D1E: F7 30 0C         STB   $300C          flip screen
117       4D21: C6 20            LDB   #$20
118 
119 3) 'sidepcktb'
120 
121   - Bootleg heavily based on the World version, so ingame bugs about bonus lives, player 2 inputs and screen flipping are still there.
122   - 2 little differences :
123       * Lives settings (table at 0x4696) : 06 03 02 instead of 06 03 09
124       * Timer settings (table at 0x9d99) : 30 20 18 instead of 40 30 20, so the timer is faster
125 
126 Additional notes:
127 ----------------
128 - sidepckt and sidepcktb don't have cocktail mode at all, while sidepcktj has a 'cooperative' cocktail mode; when it's the p2 turn,
129   the screen scrolls and a 'flipped score area' is shown on the other side, so the 2nd player just continues the same game.
130   Note that the screen never flips in any case.
