- Midway PCB sets: (cursory descripton)
* Midway Space Invaders Deluxe (and Deluxe Cocktail) use a special midway-made PCB set
which is significantly different from the taito ones.
* Midway Space Invaders II (only produced as a cocktail) is also significantly different hardware from the Taito SI hardware, but additionally has different (head to head) gameplya, as well has having two sound boards instead of one.
TODO: this needs to be emulated properly
* Both midway space invaders games' sound is different from the taito ones (particularly the shot sound) due to using slightly different components on the discrete section.
TODO: this needs to be emulated properly
NOTE: The discrete components, particularly for the shot sound, differ between Taito and Midway audio daughterboards.
TODO: figure out the difference between the Taito and Midway discrete boards and emulate them both properly. Figure out what the current discrete setup is trying to emulate.
* 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.
* [Space Invaders II] from Midway (only produced as a cocktail) uses an extra sound board for the simultaneous 2 player head-to-head sounds.
TODO: remove Space Invader 'invaders' set from mw8080bw.c, it does not belong there at all
- Taito-USA-made 'trimline' PCBS do not match the taito pcbs either.
