| 12 | - Space Invaders Deluxe still says Space Invaders Part II, |
| 13 | because according to KLOV, Midway was only allowed to make minor |
| 14 | modifications of the Taito code. |
| 15 | |
| 16 | - DIP settings/locations verified from manual for: |
| 17 | sitv, sicv, invadpt2, lrescue, invasion, invrvnge |
| 18 | |
| 19 | - The Taito Space invaders hardware comes on at least five board types; |
| 24 | 20 | The Taito manufactured ones are: |
| 25 | 21 | * The "L-shaped" PCB set, Upright, B&W only |
| 26 | 22 | * Three pcbs in a stack, often called the '3 layer pcb set' (most common) |

| 110 | | * All Midway Space Invaders games ([Space Invader Upright], [Space Invader Cocktail], [Deluxe Space Invaders Upright], [Deluxe Space Invaders Cocktail], and [Space Invaders II]) use the same 8080 mainboard, with no emulation-relevant differences between revisions. |
| 111 | | * [Space Invaders II] from Midway (only produced as a cocktail) uses an extra sound board for the simultaneous 2 player head-to-head sounds. |
| 112 | | TODO: remove Space Invader 'invaders' set from mw8080bw.c, it does not belong there at all |

| 110 | - Taito-USA-made 'trimline' PCBS do not match the taito pcbs either. |
| 182 | 111 | |
| 112 | |
| 113 | To Do: |
| 114 | ----- |
| 115 | |
| 116 | - Midway PCB sets |
| 117 | * The discrete components, particularly for the shot sound, differ |
| 118 | between Taito and Midway audio daughterboards. |
| 119 | + Figure out the difference between the Taito and Midway discrete |
| 120 | boards and emulate them both properly. |
| 121 | + Figure out what the current discrete setup is trying to emulate. |
| 122 | * Remove Space Invaders 'invaders' set from mw8080bw.c, it does not belong |
| 123 | there at all |
| 124 | |
| 125 | - Space Chaser (schaser) |
| 126 | 1. The "missile" sound is incorrect. This is how it should be: |
| 127 | It should be a constant "klunkity-klunk", and should only be |
| 128 | heard while missiles are seen to be moving. When the red |
| 129 | missiles speed up, there should be more "klunks per second" |
| 130 | with the pitch staying constant. |
| 131 | 8/8/8 D.R. - Who says? According to the schematic the sounds are |
| 132 | correct. Make a video showing otherwise or trace SX0 & SX1 on |
| 133 | a real PCB to find the difference. |
| 134 | Currently it beeps every time a player eats a dot. Seems right. |
| 135 | 2. If "Hard" mode is selected, numerous bugs appear which |
| 136 | could be either an emulation fault or a bad rom. Some |
| 137 | bugs are: |
| 138 | a. Graphic error halfway up the left side |
| 139 | b. Score adds or subtracts random amounts |
| 140 | c. Score not cleared when starting a new game |
| 141 | d. Game begins on the wrong level |
| 142 | |
| 143 | - Space War (Sanritsu) |
| 144 | * I seem to recall that the flashing ufo had its own sample |
| 145 | sound, a sort of rattling noise. Unable to find evidence |
| 146 | of this (so far). |
