Hi, I've been reading modding tutorials and have downloaded the proper programs, but nothing seems to work. I even do things exactly the way videos show to, exactly the way tuts tell to, but it all ends up as not showing up in Halo 3, and as corrupt in the system memory. I've tried both films and maps, forge and Johnson, Hexes and Mirage, and I always rehash and resign. I saw something on here about an update that might prevent me from modding, and I was wondering if that might be it. Furthermore, if it is, how to delete the update, and if said deletion will harm the Halo 3 experience. Any suggestions/tips would be much appreciated. Thanks.
