I developed my own tool a long time ago and it still serves me well (and I have no plans to release it, so no need to ask :) ). If you want to get into IFF editing but don't want to program your own editor, I highly recommend a good hex-editor like WinHex - it's way better than relying on a pre-made application you don't understand. None of the public editors are any good, either because they're no longer maintained, because they contain errors in the file layout or both.
Hello Tsukasa Wanna Know if you have any editor. IFF Thanks
