METAL SLUG 3

[FIX] For those who can't launch the game anymore, READ IT !
Hey guys, my friend coudn't play the game anymore since the last update.
It seems that I could fix his game by telling him to delete ONE file.

You have to go into your AppData folder, and find the Mslug3 folder.
In it, you have a UserDefault.xml. This is the file where the game keeps your user parameters like resolution, scanlines etc.

Delete this file, and launch the game. Metal Slug 3 will launch in Windowed mode (by default).

Try it and tell me if this works for you as well.



For those who have freeze with the game, try this : http://steamcommunity.com/app/250180/discussions/0/540744935086577432/

Had this problem creep up again but editing the file itself didn't help this time, and your method got my game working once more, cheers!

That was nice to help you guys ! :)
Can someone on the moderation side put this thread on sticky to help other people with this issue ?

Weird. Are you sure you deleted the file ? And what's your issue ? (game's crashing at launch ?)

Are you sure you weren't in the Roaming Folder ?

If you're running on Windows Vista/7 (don't know about 8), you can find mslug3 folder in AppData/local, or AppData/Roaming.
Be sure you can see hidden files.

It's not working for me. I deleted "UserDefault.xml" already but the game just won't launch.

I tried everything from what the forum said:

- Open steam and the game by 'Run as Admin'
- Reinstall the game
- Verify the game cache
- Reinstall DirectX
- Repair al the vcredist
- Delete the UserDefault.xml

And I restarted my PC EVERY single time and the game still won't launch ever since I updated it!!!
