Hacking 00000005.app U8 Packing parameters?

[madmikeuk]

Hi,

I'm making a custom VC WAD, and I'm injecting a new emanual.arc into 00000005.app. But packing it with IMD5 + no LZ77 just gives me "System memory is damaged" when I launch the channel in the System Menu. Anyone know what header I should be using for this archive?

Most likely just a regular U8 archive, but I don't know.
