F-Zero HX - A F-Zero GX Save Exploit

Post by FIX94 » Mon Jul 02, 2018 12:02 am

So, here we are yet again, with a new exploit ready to try.

Make sure to first read the README of the project.
Then, grab yourself the current release and install it with a softmodded Wii and GCMM.
The exploit loads a boot.dol installed on your memory card converted with dol2gci (as found in Home Bros) so make sure to also install one with GCMM, it will just crash otherwise.

If you are interested in the source its included on the github page.

See it in action right here loading swiss gc here:

Thanks, another game we can exploit *insert thumbs up emoticon*

Sad that we can't exploit the inital loading of the save file ... or can we?

quite honestly I'm already very happy that this was possible at all, without all the recent documentation of the replay save files it would not have been so easily doable to be honest as f-zero save files are rather special. also, this exploit just *barely* works out as it is because of some leftover data on the stack that we can modify in the situation of the replay list being created so I'm not too sure if really any of the other save file types would offer anything similar to that.

Impressive! Thanks a lot. :D
Very interesting to learn from these exploits as well.

just pushed up a new version that adds a workaround for loading dollz compressed files, it was related to a small bug in dollz.
