    R-Type Irem M72 Cap Question for Jamma sound

    I need a little help from someone that has a Japanese R-type board. I would like to verify the values of a few of the caps around the amp.

    The Japanese version looks like this.



    Apparently there are two versions of the R-Type hardware. The American version licensed by Nintendo was not set up to use the on board amp to produce amplified sound to the JAMMA edge.

    Below you will see an American version of R-Type that is missing Caps at C101, C102 and C108 positions.



    Can someone that has the Japanese version verify what caps are needed at those three positions?

    Thanks!

    C101+ 102 : 2200uF 16V
    C108: 1uF 50v

    I have 5 M72 Japanese boards, including an original R-Type. They all use these same caps.

    I did not know you could do that, I thought different games required different PALs even on the same hardware....

    On some Irem boards the PALs don't even do anything. I think someone had one and removed the PAL and nothing different happened, pretty weird.
