    Adding bitmask to adx.

    Hello all, I'm new to the forum and was hoping someone could help me out, I'm working on a 6E adx and I would like to add a flag so I can see if its in AE or not, looking at the hack location 0x0039 bit 3 & 7 are what I need to add, the only problem is I have no idea how, I thought that the packet offset was where I would put 0x0039 but that must be wrong and I also have no idea how to setup the operation, well I believe its an AND logical bit operation but how do I know what to put in for the operand and result? If anyone can help out I would really appreciate it.

    First you have to find it in the hack/disassembly, which I can't? Not sure it is in MAF? Then replace something in Data Stream like Prom ID with it and make a new Value in TunerPro RT for it.

    Have you looked at the ALDL.ds files? IIRC A58.ds is 89 and A100.ds is 90 models?

    Index doc at bottom to look them up.

    Thanks Mark, I looked at all the ALDL.ds files but didn't see what i'm looking for, I have a copy of the APYP and ARAP hac but they are not well commented, anyways this is what I did find.
