Super Comboy Sound Module

[pxlbluejay]

I recently got a Super Comboy(Korean SNES) Whick is basically a PAL SNES That says 슈퍼컴보이 on top of it and has Korean labels on the buttons and everything, and when I opened it up, I found out that it does not have a sound module. Since I don't have a regular PAL SNES, I have no way of knowing if this was Korean exclusive or not. Is it only the Super Famicom that has the sound module or is it the Comboy that doesn't have the sound module?

The Super Comboy is ntsc,same as the super famicom and US snes.

As for the sound module(apu) that was in first revision sfc and US snes,the super comboy didn't release until 92 from what I found online.
