Okay, so, this year I have been shamelessly playing my own games, and when I was playing Onyx 2 yesterday, it crashed on me due to a missing "2003misc1" file. I'm not sure how many other people have had this issue, the game crashed when I was using a miss-able secret skill, but just incase it has happened to others, here is the file.
Just insert it in the game's "Battle" folder and you're good to go. =)
