So some recent happenings over on Shmups Forum have brought up a question for me that doesn't appear to have a clear answer. As I'm sure you're all aware, vanilla MAME uses INP version 3.0, whereas WolfMAME uses INP version 3.5. My question is, what exactly are the differences between the two?

There's extra info stored in the header, but done in a way that should be backwards compatible to regular MAME. The difference in INP version number also makes it easier to determine which was used to make the INP.
