Some Halo 3 maps just don't work

[Chillstice]

This isn't exclusive to this script - exporting the map variants directly from a hard drive using Horizon yields the same result - but I was hoping to get some help with this. Also I don't really know who else to ask because this is such a niche thing.

Some Halo 3 .mvar files (when extracted from an old Xbox 360 HDD) and installed in the Halo The Master Chief Collection\halo3\map_variants folder just refuse to appear in-game. This seems to be random because it doesn't matter what combination of characters are in the filename or the file size. About half the old maps just don't work and idk why.

Has anyone else run into this issue? Does anyone know a work-around? I really need Neverland Ranch to work so I can share this relic with the world.

Here's where you can download the non-functioning .mvar: https://s.chillstice.com/T3H0i

Looked into it. Is this your map? https://imgur.com/a/5W7wqm5 I put it on a USB and saved a new copy named "BROKEN" with my 360. I was able to load that up fine. I wasn't able to see the original in the custom games lobby or forge. I tried renaming the map (the file name in windows and in the file itself since it spells the name it was saved as) and that didn't work. I'll continue to look into the issue.

Maybe the map file is corrupted somehow? It's meant to be for Foundry and it's a crazy 3-dimensional maze. Somehow I managed to find a video of the map and gametype being played: https://youtu.be/7ZY13cpWa8k?t=374

Also thanks for testing it out on 360. I would have done that myself if I still had a 360 xd

I have the file on a USB again but correctly this time. I think I screwed something up when using horizon to replace the file last time. I'm trying again now.

Ah, yeah Horizon is a bit clunky. Thanks for helping me with this, it's strange and frustrating.

Okay I have it working after putting it on a USB with horizon then resaving it on the 360 and extracting the new save with horizon. Neverland.zip Looking into why it didn't work in the first place now.

Holy hell, it works for me too. Thanks this is awesome.

Did you just have to re-save the map? Some of these maps were last saved over a decade ago.

I can provide you with more original map files that worked/ didn't work if you need them.

The original file you sent seems to not show up when placed in the built in directory. When I placed it into the private directory it seems to show up just fine. Try placing the files that don't work into the private directory and see if that solves your issue. The private directory should be located at: C:\Users{USERNAME}\AppData\LocalLow\MCC\LocalFiles{XUID}\Halo3\Map Remember to replace {USERNAME} and {XUID} with whatever your info is.

This works for the most part, but there are still a couple maps that just don't work, but they're random garbage ones so I'll cut my losses. Thanks for spending the time to figure this out. It might even be nice to put a note regarding this in the guide.

I'd like to try to find out why they don't work. If you don't mind sending the maps that don't work I'll look more into it in case others have this issue.

ah ok, here's the ones that refuse to work: https://s.chillstice.com/BhOv2 Keep in mind that I probably made these back in like 2008 and they're probably really dumb and or stupid.
