Custom MarioKart Wii mods #553

Closed calvinhendriks closed 2 years ago

calvinhendriks commented 3 years ago

Nice work on the custom WFC server! I got it to work on a vanilla version of Mario Kart WII. However, I try to use some custom distribution (custom maps) and it gives me error 23404. Now I know these patchers that belong to these custom distros change the url to wiimmfi.de, but I have setup a web server which forwards these urls to the custom WFC server (this project). If i patch the normal ISO to not use SSL and use the wiimmfi.de domain, it works. I know that these mods use something called LE-CODE and I was wondering if this makes it incompatible with the custom server.

LE-CODE in its default form is incompatible with servers other than Wiimmfi. You would need to patch the lecode-XXX.bin binary in the game image to disable the built-in Wiimmfi patch, and then run a normal Wiimmfi patcher over the ISO. Assuming these mods are running on the latest version of LE-CODE, all you'd need to do is open that binary file in a hex editor, search for 48 00 00 6d 80 01 00 0c and replace that with 60 00 00 00 80 01 00 0c which will disable the builtin Wiimmfi patch and makes LE-CODE packs behave like normal Mario Kart Wii with regards to server connections.

We aren't actively testing if LE-CODE still works properly on non-Wiimmfi servers, but I don't think it has that much special code that would break on AltWFC. Still, we can't give any support for running LE-CODE packs on non-Wiimmfi servers, so if you run into any issues please don't report them to Wiimm, me, or the CT pack author; instead, report them to the custom server creators.

Hey,

Thx for the reply!. So i changed the hex code in the lecode-PAL.bin (i use a pal iso) inside the distros ISO patcher (Variety Pack) and patched a vanilla ISO. I still get the 23404 error :( Can you tell me what the wiimmfi patcher does exactly? does it only change the domain names? And what does changing the hex code do exactly? should I still patch with a wiimmfi patcher after changing the hex code? if so ? why? Thx a lot for your help!!

Patching that code removes all Wiimmfi patches from the LE-CODE. This means you still need to apply normal patches for a custom server - changing HTTPS to HTTP and changing nintendowifi.net to your server's domain.

I wanted to let you know that I got it to work (using the binary swap you suggested). Thx for the help! My friends will also thank you when we have an epic LAN party in a few weeks. Keep up the great work on wiimmfi and mario kart modding in general :)

Hi! So I'm trying to do the hex edit, but can't seem to find any results. I already have my server set up, but 23404 is haunting me. Can anybody give me a step by step reference of what should I do? Thank you! (Also I'm editing lecode-USA.bin with HxD).
