The Organized Assetsfb.wad
I didn't know where to actually post this but this will serve as an important piece for anyone modding the Gamecube version of X-Men Legends II: Rise of Apocalypse
. I went through the assetsfb.wad and did a little clean up in removing a bunch of unused files that the developers left in the final build (ex: empty character and enemy files, unused character files of heroes that share the same ID with another hero, and maps specifically). And believe me, there was a damn ton of unused files that took a load of space.
The image below is a comparison of the original assetsfb and the organized one I did the clean up for:
That's a lot of space saved!
With that said, image below will direct you to the download containing the updated assetsfb.wad for your X-Men Legends II GCN needs, in freeing up much more space, and allowing you to install/create more mods than what your original assetsfb could handle. If you previously have any mods installed, just simply copy the character files, herostat.engb, etc. over to their respectful locations.
I still strongly recommend you keep a backup of your old assetsfb, in case you end up missing any files.
