Some mods i really want involve messing with your minecraft jar file. Such as single player commands, x-ray mod, and some more. whenever it involves messing with your jar file it either involves completely deleting META-INF or deleting everything in META-INF except Manifest.mf. whenever i do so (and i follow every step the install instructions say) minecraft either crashes with an error or just wont boot up. (i press play, then the launcher closes, then one second later the launcher re-opens and has no error message. i have to use my backup jar file to get it to launch)
Can you explain why editing META-INF the ways those mods say CRASHES my game instead of working like it says it should.
