The file you want to replace is 0000001.app. Just rename the 000000c.app to it and replace it. Wad unpackers will always call it 00000000.app, 00000001.app, ... no idea why. I personally used wadmii from the wii.cs tools for the job btw.
will try that out and post my results here, that was a fast reply. ü thanks FIX94.
