Who might need or want this batch file MOD?
If you are a manual mod installer, and you have already created full alternate Valheim
game directories or you plan to, then this little menu makes using them very
easy.

Features:
Batch file can be placed and ran from anywhere in your system, like your Desktop.
Runs Steam if its not already running, closes itself after launching steam & game.
Your choice of command line switches.
Does not change your Valheim directory in any way.

-----------------------------------------------------------------------
Why you might want to choose using FULL Game Directories over a multi mod single directory solution:

- Some mods change image asset files in the base game directory valheim_Data (HD Valhiem for ex.)
- Others change the base files in the BepInEx folder structure outside of the plugins and config folders
- Others add a patchers directory to BepInEx which support mods you may not want to run all the time

Using my game directories for example :

Fightclub: Only 15 mods trying to tackle FPS/nSyn issues; does not have High Def assets, or any deep level mods that change the game files. (Required by my team)

ValheimMod: This private server does not allow any mods that impact basic vanilla play, no god modes, no builder tools, minimum changes to available items other than stronger mobs and tools to fight them.

Superman: High Def is the standard, mods that change many of the BepInEx files and patchers along with extensive builder capability for private server/local world play. (Excess of 70+ mods)

The full directory solution is primarily for compatibility issues, or light versus heavy mods for different game play, (FPS/nSyn) issues. And finally, we have the Builder versus the Boss killer mod packs. Your mileage may vary!

-----------------------------------------------------------------------

If you know how to create full alternate Valheim game directories then you know how to use this!

All you really need to do is edit the names of your game
directories at line 29.

::Edit the following game directories or even add more!!!
if %M%==2 set gamedirectory=Fightclub
if %M%==3 set gamedirectory=ValheimMod
if %M%==4 set gamedirectory=Superman
if %M%==5 GOTO EOF

All other minor options are very visible in the comments of this very small batch file.
