I wasnt aware that was possible? How does the mugen.exe reference which screen pack youre wanting to use?
in the data folder there's a file called mugen.cfg (same file you use to change the screen resolution, difficulty and game speed). Open it up and look for this:
; Set the motif to use.
; Motifs are themes that define the look and feel of MUGEN.
; This is not accessible in options screen.
; Note: If you install a motif that overwrites system files (not recommended)
; you may need to set the motif line to use data/system.def instead.
; motif = data/system.def ;Use this line if using a motif that overwrites system files.
motif = data/system.def
Next time you want to change a screenpack keep it its own folder instead of overwriting the files in data and change mugen.cfg to this
motif = data/whatever_you_call_your_new_screenpack_folder/system.def
alternatively
You make a batch (.bat) file for the specific screenpack.
- Open notepad or any other text editor
- type: mugen -r whatever_you_call_your_new_screenpack_folder
- Save it as whatever.bat in your mugen folder (it's very important it doesn't have another extension like .txt)
- Double click it and it'll launch your screenpack instantaneously
I don't mean to toot my own horn, but if you want an example of how to make this work, I tried to make this screenpack's (http://mugenguild.com/forum/topics/the-last-blade-2-screenpack-lifebars-171396.0.html) installation foolproof.
