| 60 | 1) 'exprrada' |
| 61 | 61 | |
| 62 | | - "@ 1986 DATA EAST USA, INC." (US) |
| 63 | | - Number of enemies on "shoot" stages is determined by the level |
| 64 | | (see code at 0x5d21 where location 0x0e is level number-1). |
| 65 | | Note that time tables are coded backwards (locomotive first, |
| 66 | | then 5th wagon, then 4th wagon ... up to 1st wagon). |
| 67 | | This number of enemies is also supposed to be determined |
| 68 | | by "Difficulty" settings (DSW1 bits 3 and 4). |
| 69 | | There is however an ingame bug that reads DSW1 bits 4 and 5 : |
| 70 | | |
| 71 | | 5D2F: AD 03 18 lda $1803 |
| 72 | | 5D32: 49 FF eor #$FF |
| 73 | | 5D34: 4A lsr a |

| 75 | | 5D36: 4A lsr a |
| 76 | | 5D37: 29 06 and #$06 |
| 77 | | |
| 78 | | So number of enemies is also determined by "Demo Sound" setting ! |
| 79 | | Correct code shall be : |
| 80 | | |
| 81 | | 5D37: 29 03 and #$03 |
| 82 | | |
| 83 | | - Time for each wagon on "shoot" stage is determined by the level |
| 84 | | (see code at 0x6873 where location 0x0e is level number-1). |
| 85 | | Note that time tables are coded backwards (locomotive first, |
| 86 | | then 5th wagon, then 4th wagon ... up to 1st wagon). |
| 87 | | - In the US manual, "bonus lives" settings are told be either |
| 88 | | "Every 50000" or "50000/80000". |
| 89 | | However, when you look at code at 0xe4a1, you'll notice that |
| 90 | | settings shall be "50000 only" and "50000/80000". |
| 91 | | - "Coin Mode" as well "Mode 2 Coinage" settings (DSW0 bits 0 to 4) |
| 92 | | are undocumented in the US manual. |
| 93 | | "Coin Mode" is tested though via code at 0xe7c5. |
| 94 | | Coinage tables : |
| 95 | | * 0xe7e2 : COIN1 - 0xe7ea : COIN2 (Mode 1) |
| 96 | | * 0xe7f2 : COIN1 - 0xe7fa : COIN2 (Mode 2) |
| 97 | | - "Force Coinage" (DSW1 bit 6) setting is undocumented in the US manual. |
| 98 | | It is tested though via code at 0xe794. |
| 99 | | When this Dip Switch is set to "On", pressing COIN1 or COIN2 always |
| 100 | | adds 1 credit regardless of the "Coinage" and "Coin Mode" settings. |
| 101 | | - At the beginning of each level, you have text in upper case |
| 102 | | which gives you some hints to pass the level or some advice. |
| 103 | | - In this version, due to extra code at 0xfd80, you only have 4 wagons |
| 104 | | for the "shoot" stages instead of 5. |
| 105 | | - Continue play is always available and score is NOT reset to 0. |
| 106 | | |
| 107 | | 2) 'exprrada' |
| 108 | | |
| 109 | 62 | - "@ 1986 DATA EAST CORPORATION" + no code to display the Warning screen (World) |
| 110 | | - Same way to code number of enemies in "shoot" stages as in 'exprraid' |
| 63 | - Same way to code number of enemies in "shoot" stages as in 'exprraidu' |

| 125 | | more enemies than in 'exprraid'. |
| 78 | more enemies than in 'exprraidu'. |
