A problem in LF2

You can use LF2 2.0a exe for your mod instead.

And how do I do this?

I downloaded XLF-Omega at ur Page.

I think you're out of luck,  XLF-Omega is for v1.9c only AFAIK. Though you can try to copy and paste data files and sprites (with each sprite having a mirror) to v2.0a (you can download v2.0a here).

So I'm copying just all files from XLF to the Little Fighter 2 v2.0a and overwrite the files?
I mean why should I search for each sprites, for a mirror file, when I could probably just copy all files instead.
