y do you have 2 file replacement codes?
do you mean these two codes?
File Replacment: v2.1a[Phantom Wings]
File Patch Code v3.5.1 (NTSC-U) [Phantom Wings]
are they pretty much the same thing?
Yeah, it's been stated that using those two will cause some crashing.
Just a name change to the loader since it can play music now.
