gcm-output of GCMUtility not playable in Dolphin?

[hjiuizjjhghh]

I used GCMUtility on Mario Kart to create a much smaller gcm file from it. The resulting gcm (I created it twice and checked the sha1-checksums to be sure there was no error on disk or RAM) crashes when trying to load a specific course in the game. Is this an issue in dolphin with GCM? (afaik the gcm should not change the game data but only replase padding)

Thanks

If the goal is getting smaller files (e.g. without changing game data), it's probably easier to use Dolphin conversion features to compress the source file to GCZ, or preferably, RVZ. If you want to actually edit the ISO contents, I would suggest using WIT instead to do the modding, then optionally compress the final file via Dolphin...
