As mentioned before, it is better to have schematics to know what sounds are generated from the game. But since those are very hard to find, you would have to have a working pcb, set up in a test rig/unit, or if lucky find a cab....if even possible these days to make audio recordings of what audio sounds the game generates. There are others here that can provide exact audio recording tips...assuming you ever do find a working pcb sometime later.

Be familiar with self compiling of MAME debug builds and also be familiar with disassembly of 8080 or z80 instructions from the Tranquilizer Gun game roms in hopes to find when some unknown sound effect is activated. Really look over how Carnival or Depthcharge external audio sample support works since that is same hardware (Depthcharge uses 8080 while later games are z80 based).

Keep on searching for any Tranquilizer Gun pcbs parts such as a fully working boardset ....consists of two pcbs (main board and audio card iirc) or keep searching for any schematics paperwork that the game uses. The searching might take a couple years because it took that long to find Ramtek Trivia logic schematics for Ramtek Trivia.

As for Sega/Gremlin vic dual hardware games, Derrick Renaud mentioned that many sounds make use of resistors and capacitors. Each sound effect from any of those games might require a fair amount of time spent on testing to see if audio output matches as to what is described in the logic schematics of a manual or going by recordings of actual audio sound effects from a game, or lastly by comparing actual audio hardware from the pcb.

Tranquilizer Gun logic schematics has not yet been found. Those appear to be printed on separate blue print sheets because I do have a Japanese region Tranquilizer Gun service manual but do not have the logic schematics blue print sheets.

For the time spent searching over last several years, my guess is Tranquilizer Gun paperwork might have only been printed in Japan. I have yet to see any N. American region manual prints for Tranquilizer Gun.
