You say "no biggie" like people helping you isn't a big deal... You should be grateful for all the help you're given dude :\
Coincidentally enough, these files ARE a biggie, as there looks to be a XapA compression header here, which is most likely a SEGA proprietary format. I certainly can't decompress them, for one.
I know... sorry about that.
Kinda tired.
Also, I know this shouldn't be brought up here, but,
there was a DS game that had all of it's data stored in an
SFS archive. Is there any way to decompress it?
I can't really post it because it won't compress, and
the file size is 89mb.
If anyone can pick up a copy of it, and be able to decompress
it, it would be a big help!
PS: The game II believe is Knights of the Nightmare (U).
