    I was questioning myself ''Why can't the Rev C patch be used on the Rev C Dorasu Icon card?''
    So i searched google and found out that there is a difference in the PCB, but i didn't believe it.
    Today i was checking a thread on gbatemp and one of the guys posted a pic of the Rev C card

    so i opened mine to see where the difference is.... in the end i really found some differences!
    One of the thingies has different numbers on it.
    Mine card has 215 but the one in the pic has 512.

    Now i would like that someone who has a Rev C Dorasu icon card to check they PCB to see if they too got 215 too on the same thingies. It.could be that the R4ids.cn team made other revs but accidently put the C in the PCB(or maybe they just did it to make more money cause other revs didn't work on never updates??). And someone who has a Rev B or lower revision cards to check they PCBs too.

    512 means a 5.1k resistor. In fact, 215 is just a mirror of 512.
    They are the same.

    Ok but what about this one?

    A machine can't fail to make it like that, so it seems that humans make the cards but still how could someone put 1 resistor normally and the second one flip?
    It looks like the resistors are really different

    Depending on the type of machine, they do flip resistors and I do not see the problem. I checked my tapes and they are also alternating, flipped, non flipped.

    So if the resistors are not the problem then what is then?
    Online they say its cause the PCB is different and that's the only things what's different about the DORASU Card with the other Rev C.

    Different ICs? Bad code/detection? I wouldn't know.
    I have a unused DORASU card which cannot be upgraded to 1.45, personally I'd stay away from R4ids' many revisions and stick with the SC2.
