概 要修正の提出。
詳 細Not sure if this fix is going to be approved but I will submit it anyways. The audio driver for Spiders hasn't been touched since 2005. I found a video on youtube that shows the frequency in the emulator for certain sounds is too high and I was able to try and tune it by ear. The audio driver was created by someone else based on caps an resistor values and does not use netlist (uses DAC and discrete). I was able to get desired results without changing any resistor or caps values. The firing sound on the arcade board sounds like something from Space Invaders or Galaxian this part was I was not able to fix. Maybe someone can help on this. Been trying to get a boardset for years for my collection.

in src/audio/spiders.c

* CHANGED TO SPIDERS_SOUND_CLK/21*
