Just for the hell of it i've made an Index File Reader (
http://quick.mixnmojo.com/files/IndexFileReader1.0.zip) based on Tomas' RNAM viewer, Khalek's index file specs, what I could comprehend at a glance from ScummVM and my own poking around.
While I was doing it I documented (
http://quick.mixnmojo.com/readmes/IndexFileSpecs.txt) the format of the various index files. I think its mostly right but the lfl stuff could well be wrong, someone who isnt C++ challenged like me will be able to confirm this from the ScummVM source.
Anyway, er its nothing special, I just wanted to see if I could do it. The reader, source and specs are there should anyone ever find them useful.
