    Is there any program that can check if a wii ISO or Gamecube GCM/ISO is completely fine, or any other way of checking them apart from burning them and putting them in your Wii.

    Thanks in advance.

    There is a program for checking, but im not sure if the checks work correctly after patching the ISOs

    That isn't a problem since I haven't patched them.

    If you managed to extract them they should be good (CRC32 (used by zip/rar/7z) may not be much good for detecting untampered files if a person has intent to deceive but it does detect corrupt files).
    The only thing is I know of no site that has CRC values for you to check against

    Pure isos have a set size too:

    See step 3 but modern tools should not have a problem.

    A couple of the early tools (pre trucha) could also detect whether the header had been messed with (brick block, early region free).
    I am not sure if there are any signature checking apps (we exploit a bug in the signature checking process rather than a true resigning) but that would be another way to detect tampering. Scrubbing should be easy enough to detect (does it compress?, only a few games compress without scrubbing).

    Well RegionFrii and Wii Update Manager can open the ISO and try to extract information from it. Such as name, publisher, region. I try that with every ISO before burning. If the application can open it, I assume all is OK.
    You can also use regionfrii to check whether an iso is really from the region it claims to be, or that they just region-patched it
